According to the keyboard layout wiki, keyboard configurations (for both the console and Xorg) can be conveniently set using the localectl command. In order to set a second keyboard layout, we hav...
From man xxd, the section on the -r flag (emphasis added): -r | -revert reverse operation: convert (or patch) hexdump into binary. If not writing to stdout, xxd writes into its output file with...
For most users, in $HOME/.config/gtk-3.0/bookmarks. Otherwise, if you set the XDG_CONFIG_HOME environment variable (which you can inspect with env), in $XDG_CONFIG_HOME/gtk-3.0/bookmarks. From the...
What you describe is a typical mixed authoritative/recursive resolver setup. Such a DNS server setup will respond from its own data about zones for which it has explicit configuration, and will per...
Where can I find documentation on double asterisk in glob expansion? It is discussed in the .gitignore section of Pro Git. It works in ls **/* to list all terminal files. It is supported by py...
I would consider your own tools as the central use case. Seriously, do you want to litter every while read (or your language's equivalent) with this pesky corner case handling? while read -r line ...
There are many GUI apps on my computer that show up as eg. items in the start menu. When I launch these, what if I want to control how exactly they are launched, such as setting environment variabl...
The simple and obvious solution: sed 's/^ *//;s/ *$//' Many recipes you find online will erroneously add a g flag, but these regular expressions can only match once per line anyway. (In some m...
I'd like to debug NetworkManager by stepping through it using GDB. I assume I'll have to compile NetworkManager from source to get debug symbols since file /usr/bin/NetworkManager indicates that th...
If I just used find to generate a list of files, then find's -exec argument is usually the way to run some other program on each file found. If you pipe the command to xargs, note that -P n wi...
When running sed through fish, I often encounter a problem with regexes. Many commonly used regex control characters like []{}().+ need to be escaped, even if I type the regex in a single quoted st...
The usual way is to specify an installation location with ./configure --prefix="$HOME/python" ... and then make install after make. If you don't specify a --prefix argument to configure, it ty...
Suppose I have a list of files on standard input. These may be the output of find, cat filelist.txt or something else. How can I run a command on each file in turn?
I'm not sure which exact fragment, functionality or aspect is problematic to you. Here I will make points (paragraphs) about what I used to struggle to understand, or about what I suspect may be no...
The best method is to navigate to the folder containing your Flac audio files and use the following 'for' loop: for j in *.flac do ffmpeg -i "$j" -c:a libmp3lame -b:a 128k mp3/"${j%.flac}.mp3" ...
SIGUSR1 and SIGUSR2 are user-defined signals. Imagine there is a tool designed to do something useful upon receiving one or the other. The problem is the default action for these signals is Term (...
How can I convert PDF to docx using the terminal or a Linux app? The output docx must be formatted with editable text. Some alternative solutions I've seen online using soffice and abiword output...
This isn't an answer so much as some information related to your question. We have an open GitHub issue to add searching on reactions. We can already search by post type, category, user, score, a...
To increase the activity of the site (one of the main concerns related to making Codidact grow), I suggested merging Linux Systems with Power Users on Meta. Do you agree or disagree with merging?
The reason why you don't find this in man ls is that the GNU project (that developed Coreutils) usually provides the complete documentation of its components not in classic manual pages, but in so ...
GNU Screen and Tmux allow you to run command-line programs on a server, and 'disconnect' from them but let them keep running remotely. This is great if your primary computer is a laptop and it has...
Have a look at Xpra. I only use it locally but it's intended to forward from remote hosts as well.
Technically, you don't need an /etc/hosts file at all if you have some other form of name resolution available - i.e. DNS. In practice, what you have will work nicely, and could be cut down to jus...
I noticed in winetricks that it can install windows dlls to the wine folder. It even gives an option to install almost all of them at once. When should someone install these instead of staying with...
You can edit the file you see in less by pressing v. From the man page: v Invokes an editor to edit the current file being viewed. The editor is taken from the envir...
