| What are the detriments of not setting MSFTDATA flag when making a exFAT partition? Posted: 13 Jun 2022 02:03 AM PDT I have several external HDDs that I backup data to and occasionally plugin internally when I need access to the data. I erased all partitions by making a new GPT partition table on the disk. I made a primary partition of type NTFS and then formatted as an exFAT partition: Now, I can plug this HDD into both my Unix desktop and Windows desktop and can access the files without issue. However, I noticed that my Windows partitions have MSFTDATA flag set when viewed in parted ( I haven't set this flag - will this become an issue later and will setting the flag cause issues accessing the data from Unix? What exactly does Windows (or Unix) use this flag for? |

| Extending LVM partition with unallocated space on CentOS guest system Posted: 13 Jun 2022 01:06 AM PDT I believe this is an easy question for people in the know. I have ~100 GB unallocated hard disk space that I want to use to extend my home partition. What commands do I need to run? What I want is the centos-home size to increase to the maximum possible (from 243G to about 340G) Thanks! More info: This CentOS7 is running as a VM guest on a Windows 10 Host I've found many guides online, but none were specifically answering my issue. One increased the centos-root partition instead of centos-home, so I reset the whole VM. Another guide was for moving space from root to home, so not what I need. It can't be difficult I'm just a noob. Thanks! |

| How to disable Wifi Power Save on Kali Linux Posted: 13 Jun 2022 02:04 AM PDT I am running kali with virtualbox and my wifi receiver is a usb adapter which is Asus N10 Nano. I made the settings on virtualbox for making the vb recognize my usb wifi adapter. It works but after like 5min my internet drops. Especially during the updates. I figured it out its because the "Wifi Power Save" option is on. I turned it off and tried again. When i turned it off my wifi turned off at the same time. I tried to turn my wifi on but the Wifi Power Save option turned on itself automatically. The usb icon on bottom is like red-green. It needs to be blinking green to work correctly. If i can turn off the Wifi Power Save mod permamently hopefully its gonna be blinking green. I searched for it, I did almost everything like creating directory as Then i gave the permission lspci output: It didn't work. In the end |
| Concatenate multiple files with same header Posted: 13 Jun 2022 02:11 AM PDT I have multiple files with the same header and different vectors below that.

| Why does awk do full buffering when reading from a pipe Posted: 13 Jun 2022 03:01 AM PDT I'm reading from a serial port connected to a gps device sending nmea strings. A simplified invocation to illustrate my point: If I instead try to read from a pipe, awk buffers the input before sending it to stdout. How can I avoid the buffering? Edit: Kyle Jones suggested that cat is buffering it's output but that doesn't appear to be happening: When I think about it: I thought that a program used line buffering when writing to a terminal and "regular buffering" for all other cases. Then, why is cat not buffering more? Is the serial port signaling EOF? Then why is cat not terminated? |
