![]() ![]() You can list active tmux sessions with tmux ls: $ tmux lsĠ: 1 windows (created Sat Aug 27 20:54:58 2022) You're no longer attached to the session, but your long-running command executes safely in the background. After that, press D to detach from the current session. Tmux operates using a series of keybindings (keyboard shortcuts) triggered by pressing the "prefix" combination. You can detach from your tmux session by pressing Ctrl+B then D. ![]() $ while true do echo "Hello $c" let c=c+1 sleep 1 done For example, to simulate a long-running process: $ c=1 Now that you're connected to tmux, you can run any commands or programs as you normally would. Here's an example of a customized tmux session: Scriptability, which allows me to create custom tmux sessions for different purposes.Some of tmux's features that help me and increase my productivity include: I've been using tmux on my laptops for over eight years. In addition to its benefits with remote connections, tmux's speed and flexibility make it a fantastic tool to manage multiple terminals on your local machine, similar to a window manager. Later, you can reattach tmux to the same or a different terminal. You can detach tmux from the current terminal, and all your programs will continue to run safely in the background. Tmux also decouples your programs from the main terminal, protecting them from accidentally disconnecting. How well do you know Linux?

The third and fourth columns are the user who owns the file and the Unix group of users to which the file belongs.Generally an ordinary file will only have one link, but a directory will have more, because you can refer to it as ``dirname'', ``dirname/.'' where the dot means ``current directory'', and if it has a subdirectory named ``subdir'', ``dirname/subdir/.'' (the ``.'' means ``parent directory''). The second column is the number of links to the file i.e., (more or less) the number of names there are for the file.The first column gives the type of the file ( e.g., directory or ordinary file) and the file permissions.Here is an example section of the output of ls -l :ĭrwxr-xr-x 6 eva users 1024 Jun 8 16:46 sabon ls -l gives a long listing of all files.ls -F gives a full listing, indicating what type files are by putting a slash after directories and a star after executable files (programs you can run).ls -a will list all files including hidden files (files with names beginning with a dot).Options can be combined (this is a general principle of Unix commands) - for example "ls -la" gives a long listing of all files. There are a large number of options here are some of the most useful. "ls *.tex" lists only those files ending in ".tex". "ls" on its own lists all files in the current directory except for hidden files. ![]()
