| EFI logs for logging Posted: 24 Jun 2021 12:06 PM PDT Is it possible to get some logs about (U)EFI boot?

So I need to know what blocks the computer from booting that entry  |
| Nohup output is scrambled Posted: 24 Jun 2021 12:03 PM PDT I ran/made a pooled/multithreaded python script that outputs a bunch of stuff in an order in which it operates. When I run the regular python command in my terminal I then see as expected some markers corresponding to places in the program execution (e.g. loaded, written parameters, progress, written output, etc.). I am experimenting with nohup for a remote server and when I run it both on the local computer and remote server, the output it writes to the nohup.out file is scrambled in a random order. It looks like the lines I expect are there. I am not sure if this has to do with the way it is handling the threaded process or something else. In my remote server it seems to throw an error where it does not recognize that I am in a conda environment, and throws an error when importing a package in that environment. Does anyone has any thoughts on either of these issues?  |
| Why does this KDE keyboard shortcut command not work? Posted: 24 Jun 2021 11:55 AM PDT After some digging, I managed to find that to get the name of the user's preferred terminal emulator, as set in the 'Default Applications' section of KDE5's settings, one can run this command: kreadconfig5 --file kdeglobals --group General --key TerminalApplication
In my case (running Manjaro with KDE Plasma 5), this returns the string 'alacritty'. Thus, wrapping this in $(...) and typing the resulting command inside a terminal launches the user's preferred terminal emulator (I have tested that this work). Yet, when I create a custom keyboard shortcut for KDE to run this command with Meta+Return, nothing happens. I also tried putting exec in front of it in case it was necessary, but it changed nothing. If i just set up the shortcut to run the command alacritty (which is what is returned by the first command I mentioned), then it works, but of course I want to be able to run whatever is the user's preferred terminal, not a specific one. Can anyone explain to me why it is not working? Am I doing something wrong?  |

| Unable to install gmake command on FreeBSD Posted: 24 Jun 2021 11:45 AM PDT I am trying to install gmake on FreeBSD-9.3 machine but I am getting only errors. The things I tried: Installing it via make command (make config-recursive, make install clean) with no success. "/usr/ports/Mk/bsd.port.mk", line 1014: Unknown directive Unknown modifier 't Variable .CURDIR is recursive.
Next attempt was with pkg (pkg install gmake, pkg install devel/gmake) Both of those commands provide the same error: pkg: http://pkg.FreeBSD.org/freebsd:9:x86:32/latest/digests.txz: Not Found pkg: Unable to find catalogs
Everything so far returns those Errors and I am pretty new to the world of Unix so anything will be pretty much appriciated. Thanks in advance.  |
| How to find the URI and repository name from which the package was installed? Posted: 24 Jun 2021 11:51 AM PDT I have a package installed locally and I want to find the zypper URI and the repository name from which the package was installed from. I could search for the package and find it: zypper info $PKG_NAME
but it does give me the URI or the repository name: > zypper info tcsh Information for package tcsh: Repository: @System Name: tcsh Version: 6.18.01-9.7.1 Arch: x86_64 Vendor: SUSE LINUX Products GmbH, Nuernberg, Germany Support Level: unknown Installed: Yes Status: up-to-date Installed Size: 1.0 MiB Summary: The C SHell Description: Tcsh is an enhanced, but completely compatible, version of the Berkeley UNIX C shell, csh(1). It is a command language interpreter usable as an interactive login shell and a shell script command processor. It includes a command-line editor, programmable word completion, spelling correction, a history mechanism, job control, and a C-like syntax.
How can I get the URI and repository name from which the package was installed? I'm also familiar with the zypper repos -u command to list all the repositories and URIs. But it does not help here. I want to make it automatic at some point. So if there is a way, could it be a way so it will be easy to parse the output? Like with the rpm -qf --queryformat "[%{NAME}]" command which returns the just the package name.  |

| Utilizing unique passwords for scp based on user and program Posted: 24 Jun 2021 11:00 AM PDT I am running a python Flask endpoint on an Ubuntu 20.04 remote server. The script is launched by a user on the machine. The script exposes an endpoint which another end user would visit and interact with. After interacting with the endpoint, a file will be created in a shared drive on the Ubuntu 20.04 remote server. I wish to scp that file over to another server. In particular, the problem I am trying to solve is that based on the user who spins the python process, that their credentials would need to be entered for the scp call. I am not sure about best methods to store these passwords for different users. For example, consider two users: user1 and user2: /home/user1 /home/user2 user1 decides to spin the process up end user interacts with process in the code for the script there is a line somewhere which initiates the scp scp /path/to/file.txt user1@other.remote.server:/path/to/write/file.txt this would prompt for the user password credentials ... I thought that perhaps the password could be stored in /home/user1/secret_folder and /home/user2/secret_folder and then those folder's could be queried accordingly. Apologies for the ignorance on these various issues, I am still a novice Linux user and spend most of my time doing ML work. Thank you.  |
| How to set spacing[tab] in bash correctly automatically?

| How can I su to a user with no login shell? Posted: 24 Jun 2021 10:59 AM PDT Problem In Debian 10 I want to create a user who cannot log in directly. One should only be able to access the user by using the su binary. In my Ubuntu 18.04 setup, I did exactly this and it worked like charm, but in Debian 10 I am not able to do so. Hint The user that is able to login will not have the permission to use sudo. What I've done I've setup a user with the default shell /usr/sbin/nologin. But when trying to access this user by su --shell=/bin/bash user I am not able to do so. Minimal example # useradd --shell /usr/sbin/nologin locked # passwd locked Enter new UNIX password: *secret* Retype new UNIX password: *secret* passwd: password updated successfully $ su --shell /bin/bash locked Password: *secret* This account is currently not available.

| AWS libcrypto resolve messages seen when using a boto3 library, apparently after an update Posted: 24 Jun 2021 11:44 AM PDT I'm using the s4cmd package in Python which in turn uses boto3 to communicate with a (non Amazon) S3 service. I've started seeing these warning messages on stderr. I believe this happened after an auto update to OpenSSL, but that's just my best guess. AWS libcrypto resolve: searching process and loaded modules AWS libcrypto resolve: found static aws-lc HMAC symbols AWS libcrypto resolve: found static aws-lc libcrypto 1.1.1 EVP_MD symbols

Does anyone know what these messages are, if they're ignorable, and if they are how to suppress them? The onset of these messages correlates with a lot of random SSL failures. Both in Firefox and when using boto3. I commonly see errors like [Exception] Connection was closed before we received a valid response from endpoint URL now, but when I ssh into another server I have no problem. An hour later the problems will be gone, only to reappear some apparently random time later. Additional info: I recently noticed that inside a docker container on my laptop my boto3 & s4cmd commands work while they fail on my base OS. I checked openssl version on both: # Base OS, failing openssl version OpenSSL 1.1.1g 21 Apr 2020 # Inside docker container, working openssl version OpenSSL 1.1.1 11 Sep 2018

| Evaluate multi-line output (with comments) of another command. (pip-completion) Posted: 24 Jun 2021 11:02 AM PDT In trying to make my .zshrc neater, I stumbled over the following problem/question: "How can I run the output of another command?". While I'm sure this is a simple problem, I just don't understand what I'm doing wrong. I want to add pip-completion to my config. For this, I need to add the output of $ pip completion --zsh to .zshrc: $ pip completion --zsh # pip zsh completion start function _pip_completion { local words cword read -Ac words read -cn cword reply=( $( COMP_WORDS="$words[*]" \ COMP_CWORD=$(( cword-1 )) \ PIP_AUTO_COMPLETE=1 $words[1] 2>/dev/null )) } compctl -K _pip_completion pip # pip zsh completion end
Now, the lines above simply don't look nice. Instead I tried adding the following line to .zshrc: eval $(pip completion --zshrc)
However, pip completion is not being "installed" (as opposed to when I add the lines themselves in .zshrc), but I also don't get any errors. I have a feeling zsh doesn't evaluate the # lines properly, but I'm not sure how to test it. when I run $ eval $(pip completion --zshrc) no errors pop out. Where am I going wrong? Is there a similar alternative to evaluating the output of $ pip completion --zsh in my .zshrc?  |

Excerpt about the key mentioned in the error: <key name='show-type-column' type='b'> <default>true</default> <summary>Show file types</summary> <description> Controls whether the file chooser shows a column with file types. </description> </key>
How do I fix this problem?  |
| Are interrupts used to signify that output is ready or input has completed? Posted: 24 Jun 2021 10:36 AM PDT Operating System Concepts says: During I/O, the various device controllers raise interrupts when they are ready for service. These interrupts signify - that output has completed, or
- that input data are available, or
- that a failure has been detected.
Are interrupts used to signify that output is ready or input has completed? If not, do they need to be signified by some other way?  |
| How do I get rid of underline when typing commands in zsh? Posted: 24 Jun 2021 11:01 AM PDT I use zsh with oh-my-zsh and it almost suits my needs. However, there is one thing I cannot figure out, namely how do I get rid of an underline of some parts of commands I type? Please have a look at the following screenshot to get an idea of what I'm talking about.

| How can a systemd service flag that it is ready, so that other services can wait for it to be ready before they start? Posted: 24 Jun 2021 09:55 AM PDT I have a bunch of services (say C0, C1, … C9) that should only start after a service S has completed its initialization and is fully running and ready for the other services. How do I arrange that with systemd? In Ordering services with path activation and target in systemd it is assumed that service S has a mechanism for writing out some sort of flag file. Assume here, in contrast, that I have full control over the program that service S runs, and can add systemd mechanisms into it if needs be.  |
| Check whether text contains non-ASCII characters in a shell script Posted: 24 Jun 2021 09:35 AM PDT I have a file, I want to determine if it contains only English ASCII characters. I thought this is a very common question, but when I googled it, there is no direct answer or related. According to some other questions, this is what I got so far, but this doesn't work. No matter ASCII or Non-ASCII chars, it will always determine as non-ascii. if (LC_ALL=C; [[ $TEXT = *[[:ascii:]]* ]]) then echo "Contain Non-ASCII" fi
BTW, This is a shell script.  |
