| Move Files and Change Extension Posted: 27 Oct 2021 10:27 AM PDT I have a script I've been using for a couple years perfectly to find file names within a directory and adding a CR to each line as well as renaming the extension via MV. I've always had to execute this when the files are in their final directory but now I need to do it and actually move the file to a different directory (which I've added a constant labeled DESTINATION for). I don't use Linux a lot and had a lot of trial and error getting this original code so wanted to see if there was an easy way to do this with minimal changes to my existing code if possible, just not sure how to approach it since I'm feeding the directory/filename into a variable. Any suggestions are greatly appreciated! #!/bin/bash #Declare Constants: DATESTAMP=$(date) SOURCE=/folder1/ DESTINATION=/folder2/ #Find all .pux files in the source directory. Feed those files to a while read do to be processed find "$SOURCE" -mindepth 1 -maxdepth 1 -type f -name "*.pux" -print0 | while IFS= read -r -d '' file; do #Add carriage return to all lines in found files where there isn't a CR already sed -i '/\r/! s/$/\r/' "${file}" && #Change .pux extension to .pun mv "${file}" "${file/%pux/pun}" && #echo append actions performed with date stamp to a .x2n file in folder where pux/puns files sit echo "$DATESTAMP" sed -i '/\r/! s/$/\r/' "${file}" >> "${file/%pux/x2n}" && echo "$DATESTAMP" mv "${file}" "${file/%pux/pun}" >> "${file/%pux/x2n}" done

| udev rule for connecting external display not working Posted: 27 Oct 2021 10:16 AM PDT I have created my very first udev rule to automatically setup my external display when I plug in my laptop to docking station. As things turn out it's not working (what a suprise). First things first I checked what events are being sent when I unplug and plug in my external display to docking station (the same events happen when I connect and disconnect docking station itself from the laptop with external display connected to it). Here is the output from *udevadm monitor: ### CONNECTING EXTERNAL DISPLAY ### KERNEL[12586.516063] change /devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card1 (drm) UDEV [12586.520032] change /devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card1 (drm) KERNEL[12588.090123] change /devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card1 (drm) UDEV [12588.094088] change /devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card1 (drm)

Here is my udev rule: KERNEL=="card1", SUBSYSTEM=="drm", ACTION=="change", RUN+="su vllblvck -c /usr/bin/setup-ext-display.sh"
And here is the script that it is supposed to run: #!/bin/sh # PLACE THIS SCRIPT INSIDE /usr/bin # Automatically setup external monitor xrandr_command="/usr/bin/xrandr" sed_command="/bin/sed" is_hdmi_connected=`DISPLAY=:0 $xrandr_command | $sed_command -n '/DP-1-2.3 connected/p'` echo is_hdmi_connected: $is_hdmi_connected if [ -n "$is_hdmi_connected" ]; then DISPLAY=:0 xrandr --output DP-1-2.3 --auto --right-of eDP-1 echo connecting else DISPLAY=:0 $xrandr_command --output DP-1-2.3 --off echo disconnecting fi
The script itself works just fine and does what I want it to do. I have even switched to the root user to check if su vllblvck -c part is working correctly and yes it is. I've run below command to check if the rule would even execute and supposedly it would but in reality it does not or malfunctions in some way and my external display is never set up . udevadm test --action="change" /devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card1
I would appreciate any tips on how to fix this or debug this further as udev rules topic is new to me and I've run out of ideas and google searches. And If that matters here I'm running ArcoLinux with 5.14.14-arch1-1 kernel.  |

| Linux without bash Posted: 27 Oct 2021 10:10 AM PDT I'm not new in Linux world but I never liked Bash. Generally for me programming is an art and I'm very sensitive to the language syntax. When I have to work with bash, it feels like I'm writing in Stone Age people language. Maybe Fish is not perfect shell, but it is a way better than Bash and I want to switch to it completely, but something tells me that removing Bash from the system is not a great idea. So I decided to ask this crazy question, even though I have little faith that anyone will have an answer - is there existed some usable Linux distro that have no bash out of the box?  |
| Allied Vision camera V4L2 drivers for linux Posted: 27 Oct 2021 07:42 AM PDT I've got USB camera (Allied Vision Mako Mako U-130B). lsusb -v output (abbrev.): idVendor 0x1ab2 Allied Vision idProduct 0x0001 Vision device iProduct 3 Mako Mako U-130B
But when I connect this camera I can't see any /dev/video* files. Normal Web camera works, but not this above. I found some driver for it, but this driver is not V4L2 compliant (Vimba) and doesn't create /dev/video* files, because it uses own api. I want to have /dev/video* files, because I wrote application which uses v4l2 to access USB cameras and I don't want to change my code. Do you know if exist such driver which will make that camera work like normal USB camera and creates /dev/video0 file?  |
| Do I need to unbind driver on embedded device? Posted: 27 Oct 2021 07:28 AM PDT I've been having an issue reading from gpio devices on an embedded device(usrp n310). I2cdetect gives "UU" for the particular devices that I'm trying to reach indicating that the devices are already being occupied by a chip. /sys/bus/i2c/drivers shows that the driver linked to these devices is the pca953x. Previously, I was able to read and write from a gpio device(tca6416)on the zc706 platform, however, when doing a comparison of /sys/bus/i2c/drivers, I don't see any drivers associated with that chip. The code that I'm using is the following #include "i2c_dev.hpp" int main() { int i2cfd; __s32 num; //Opening i2c adapter 6 printf("Opening bus adapter\n"); i2cfd = open("/dev/i2c-6", O_RDWR); if ( i2cfd <0 ) { printf("Failed to open /dev/i2c-6: %s\n",strerror( errno )); return (1); } //Instatiating three objects of IO_Expander class IO_Expander dba; //Reading data from the IO Expander printf("Setting slave address of device\n"); if (ioctl(i2cfd, I2C_SLAVE, 0x20) < 0) { printf("Error setting slave address:%s\n",strerror(errno)); return(1); } printf("Reading data from the IO Expander for DB-A Object\n"); num =dba.read_data(i2cfd, 0x00); if (num<0){ printf("Error reading data: %s\n",strerror(errno)); } else { printf("The input value is %d: \n", num); } printf("Leaving DB-A Object \n\n\n"); //Closing the adapter close(i2cfd); }
So, am I unable to read from the gpio devices on the n310 platform because of this pca953x driver? If so, would a correct approach be to "unbind" the pca953x driver the from the devices in order to read values from them?  |
| Use a domain in a Plesk server for mail only Posted: 27 Oct 2021 07:08 AM PDT I have a server with Plesk Obsidian 18.0.35.

| Ignoring the SED encrypted drives until after booting is completed Posted: 27 Oct 2021 06:53 AM PDT I have an Ubuntu system which boots from a small NVME disk using software encryption, TPM, etc. to mitigate against data loss in case of theft. The system is interfaced with customised PCIe hardware to record data (possibly very large quantities of data). The end-user interacts with the system via a web-interface and they are not intended to use any user accounts on the system or interact directly with it on keyboard/mouse/monitor. The system has several large drives which are intended to contain the data recorded by the system. These disks are able to be encrypted (or not) at the whim of the end-user. The large disks are SED capable (not OPAL compliant). When the SED password is set (hdparm --user-master u --security-set-pass "$password" /dev/...) we see that the disks are not accessible without password (hdparm --user-master u --security-unlock "$password" /dev/...) after they are removed and re-inserted to the host system. Excellent, the encryption is working - our data is safe (OK, safer). However, on power cycle the system pauses during the POST to prompt for a password for each drive (there are 12 of them!). This blocks the boot process. Obviously this is less than ideal for us as we have to connect a monitor and keyboard and tap in the authentication key for each disk. We don't need these disks to be unlocked at boot time. We can unlock them later (with the above unlock command) when the system is up and running and the system user asks for them to be mounted. Does anyone have any ideas about how we can prevent the password prompt from blocking the boot process?  |
| Scaling default xterm font to "Large" Posted: 27 Oct 2021 06:45 AM PDT In xterm, I would like to increase the default font size to the font5/Font5/"Large" option. I've managed to do this manually with my mouse via the control menu so far, which is brilliant, but it can become quite a burden whenever I open a new xterm window. Hence, I would like to achieve the same by setting it as my default in my .Xresources file, so that every new xterm window opens in the Large font size instead of using the manual control menu. Reading the man page and doing some further research online, I tried, in separate attempts: xterm*font: font5, xterm*font: *-fixed-*-*-*-18-* and xterm*faceSize: 12.0 to achieve a similar outcome. Whilst the first try didn't work at all, in the latter two, the font is indeed increased but rather blurred when compared with what I can achieve through the control menu option. Surely, there must be a way!  |
| Hardware accelerated lossless recording on a 6700 XT using ffmpeg Posted: 27 Oct 2021 08:24 AM PDT I'm trying to record my screen losslessly (or at near lossless quality) with hardware acceleration on a 6700 XT with ffmpeg. I'm running Linux Mint with the 5.14.14-051414-generic kernel. I've tried: ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 2560x1440 -i :0 -r 60 -vf 'hwupload,scale_vaapi=format=nv12' -c:v h264_vaapi -qp 0 output.mp4
ffmpeg says it's recording at 60 fps, but the recording is choppy and slightly miscolored. I'm assuming the color issue is from the color format nv12, but rgb or rgb8 gives an error.
I've also tried using kmsgrab: ffmpeg -device /dev/dri/card0 -f kmsgrab -i - -vf 'hwmap=derive_device=vaapi,scale_vaapi=w=2560:h=1440:format=nv12' -c:v h264_vaapi -qp 0 output.mp4
But it gives the error: [kmsgrab @ 0x558f001c8d80] Using plane 65 to locate framebuffers. [kmsgrab @ 0x558f001c8d80] Failed to get framebuffer 127: Invalid argument. pipe:: Invalid argument
The number after Failed to get framebuffer is usually 127 or somewhere from 134 to 136. I got these commands here.  |
| New keyboard layout variant not detected after reboot Posted: 27 Oct 2021 06:38 AM PDT I have added a new section to the /usr/share/X11/xkb/symbols/il file.

The potsatzi section of the /usr/share/X11/xkb/symbols/il file is a copy-paste (well, a yank-paste in VIM) of the previous section, with the following changes: - The name was changed in two places from
lyx to potsatzi. - Whitespace cleanup
- I added three Unicode codepoints in the shift-char locations, those lines have the comment
ADDED by potsatzi with the name of the character added. Other than adding the alias to /usr/share/X11/xkb/rules/base.lst, removing cache files from /var/lib/xkb/, and rebooting the system, what else must I do to get the system to recognize the new layout variant?  |

| Find: Use regex to get all files with specific directory name in path, but without another specific directory name in path Posted: 27 Oct 2021 09:06 AM PDT I'm trying to use find to return all file names that have a specific directory in their path, but don't have another specific directory anywhere in the file path. Something like: myRegex= <regex> targetDir= <source directory> find $targetDir -regex $myRegex -print
I know I might also be able to do this by piping one find command into another, but I would like to know how to do this with a single regular expression. For example, I want every file that has the directory "good" in it's path, but doesn't have the directory "bad" anywhere in its path no matter the combination. Some examples: /good/file_I_want.txt #Captured /good/bad/file_I_dont_want.txt #Not captured /dir1/good/file_I_want.txt #Captured /dir2/good/bad/file_I_dont_want.txt #Not captured /dir1/good/dir2/file_I_want.txt #Captured /dir1/good/dir2/bad/file_I_want.txt #Not captured /bad/dir1/good/file_I_dont_want.txt #Not captured
Keep in mind some file names might contain "good" or "bad", but I only want to account for directory names. /good/bad.txt #Captured /bad/good.txt #Not captured
My research suggests I should use a Negative Lookahead and a Negative Lookbehind. However, nothing I have tried has worked so far. Some help would be appreciated. Thanks.  |

| Why this 'useless use of cat' with `detex` is 10x faster than the alternative? Posted: 27 Oct 2021 07:01 AM PDT I'm counting words in LaTeX files and intuitively used the command: $ cat *tex | detex | wc -w
I then immediately noticed he useless use of cat, and did the task again with: $ detex *tex | wc -w
Being proud of myself for avoiding an extra process, I wanted to check how many precious milliseconds I saved by not using cat. I was then very surprised to see that the version with cat was literally 10 times faster: $ time cat *tex | detex | wc -w 5000 real 0m0.013s user 0m0.005s sys 0m0.007s
$ time detex *tex | wc -w 5000 real 0m0.144s user 0m0.124s sys 0m0.014s
What is the reason for this massive speed difference? Is cat just so much faster in reading files from a disk than detex?
I generated 5 example "LaTeX" files for benchmarking with: $ for i in {1..5}; do shuf -n 1000 /usr/share/dict/words > "file${i}.tex"; done

After the update the driver manager marks the NVIDIA driver as installed, but the Intel graphic card has the following sentence written below "This device is not working" and the only option possible is "Do not use this device".
Both xserver-xorg-video-intel, mesa-utils and nvidia-settings are still installed (I've also tried to reinstall them) and I have SeureBoot disabled. When I try to run nvidia-settings it return an empty page and the following error is displayed: ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system
How can I fix this situation? Thanks!

| Running multiple emulators with the same AVD is an experimental feature Posted: 27 Oct 2021 10:06 AM PDT I was able to get a remote viewer set up on my mac to remote view a Fedora server desktop. I run ~/android-studio/bin/studio.sh to launch Android Studio. I open AVD manager and try to boot up an emulator, but I get message AVD is allready runing ... 
and when I try to boot emulator device1 from command line emulator -avd device1
I get message emulator: ERROR: Running multiple emulators with the same AVD is an experimental feature. Please use -read-only flag to enable this feature. so overwhelming evidence is that device1 emulator is already running, and yet when I run command adb devices I get messages List of devices attached indicating no running devices ... so whats up? edit I delete all *.lock files, and press play; the dialog did not appear, however, the emulator also did not appear, but when I ran adb devices, no devices were shown, and then I pressed play again, I got the same dialog. edit I create new device and booted from command line and got $ emulator -avd device3 Warning: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled ((null):0, (null)) emulator: INFO: QtLogger.cpp:66: Warning: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled ((null):0, (null)) failed to create drawable failed to create drawable failed to create drawable failed to create drawable failed to create drawable failed to create drawable failed to create drawable failed to create drawable getGLES2ExtensionString: Could not make GLES 2.x context current!

| Is there a way to make the local command work portably to dash ksh bash and zsh? Posted: 27 Oct 2021 10:23 AM PDT In dash (and in bash zsh and some other shells) the command local works to make a variable scope limited to that function (and descendants in some cases). That enable the possibility of making a variable limited to that function internals only (and descendant function calls in some cases). For example: testlocal(){ local IFS IFS=123 echo "internal IFS = $IFS" testdescend } testdescend(){ echo "descended IFS = $IFS" } IFS=abc testlocal echo "external IFS = $IFS"
Produce this output on execution in dash (and bash and zsh): $ dash ./script internal IFS = 123 descended IFS = 123 external IFS = abc
Which means that the IFS remains local to the function (and descendants). However, ksh is different, doesn't accept local: $ ksh ./script ./mt2[3]: local: not found [No such file or directory]
Changing the word 'local' to 'typeset' makes the script (almost) work in ksh but dash doesn't recognize typeset. And, to make the scope dynamic (descend to called functions) in ksh, the word function must be used to define functions: function testlocal { typeset IFS IFS=123 echo "internal IFS = $IFS" testdescend }
Which further complicates portability to dash. The question is: How to make the original script work also in ksh ? Is it possible to avoid a test for which shell is running the script?  |
| MDADM - Stop Resync and Force Clean - Possible and/or Safe? Posted: 27 Oct 2021 09:01 AM PDT I have been having issues with my FileServer recently. See "rcu_sched detected stalls on CPUs/tasks" - jiffies - ESXi Ubuntu 16 FileServer Guest I just rebuilt it since I couldn't get any guidance on the issue. Unfortunatley, its resyncing my array again. Seeing how this has been done multiple time in the last few days, I'm fairly confident that its "in sync". I have a few questions to that regard. - When it resync's what is happening, is it just doing read operations on every piece of data? I feel i'm really abusing my HDD's at the moment
- Can I cancel resync? (I still want to be able to use the MDADM Though!)
- So Can I force it to "clean" state and remount?
- Is resync automatic when you mount a new MDADM (This is a new VM), or is there an error in the metadata that is forcing a resync and I NEED to let it finish. (It takes about 24 Hours and my server is extremely slow during that time)
Thanks! Update: There are 4x 5tb HDDs in raid5 passed through via mapped raw lun to a VM guest which then exports nfs and smb. This question is mostly about if the commands i want exist for mdadm and what sync does.  |

| How to send a file using xmodem protocol from the command line Posted: 27 Oct 2021 10:22 AM PDT I have a scope attached to RX and TX lines of the serial port. If I do: cat /dev/ttyS0
I get a steady stream of 'C' characters so the remote side is up and sending. If I do: cat {filename} > /dev/ttyS0
I get a burst on TX line w/o any protocol. If I do the following: /usr/bin/sx -vv -k -X -b -c send {filename}
TX line remains inactive. File is binary and expecting xmodem 1K protocol. What am I doing wrong?  |
