Check if it's OK to spawn tmux. Bool's Rools.

The command cechks if we are connected to a X11 console, if the $TERM var noct yet contains a "screen" derivat, and only then attachs to tmux. You could add a test for interactive shell [[ $- == *i* ]] but your .bashrc has that already, I bet.
This is sample output - yours may be different.

[[ $DISPLAY != "" ]] && [[ ${TERM%screen*} != "" ]] && tmux attach

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Share Your Commands

Check These Out

reduce mp3 bitrate (and size, of course)

Useful if you have to put some mp3 files into mobile devices (ie mobile phones with no much memory)

execute a shell with netcat without -e

Shorter version with proper stderr redirection .

Simple complete system backup excluding files or directories

You can exclude more system folders or individual files which are not necessary for the backup and can be recreated after the restore procedure, like /lost+found, /mnt, /media, /tmp, /usr ... Restoring the above backup procedure is as simple as becoming root and typing: $ tar zxpf backup.tgz -C / You can extract any file or directory out of the backup.tgz file for recovery, for instance, if you have a corrupt or mis-configured fstab file, you could simply issue the command: $ tar zxpf backup.tgz /ect/fstab -C / Other options: v add verbose option to see files processed A far safer solution is to restore the desired files under a different directory, and then compare, move, or update the files to their original locations afterward.

Find files of two different extensions and copy them to a directory

List processes sorted by CPU usage

zsh suffix to inform you about long command ending

make, find and a lot of other programs can take a lot of time. And can do not. Supppose you write a long, complicated command and wonder if it will be done in 3 seconds or 20 minutes. Just add "R" (without quotes) suffix to it and you can do other things: zsh will inform you when you can see the results. You can replace zenity with other X Window dialogs program.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Concatenate (join) video files

Use mencoder to concatenate (join) multiple video files together.

Open files in a split windowed Vim

-o acts like :spit. Use -O (capital o) for side-by-side like :vsplit. Use vim -d or vimdiff if you need a diff(1) comparison. To split gnu Screen instead of vim, use ^A S for horizontal, ^A | for vertical.

cd into another dir to run a one-liner, but implicitly drop back to your $OLD_PWD after

Obviously the example given is necessarily simple, but this command not only saves time on the command line (saves you using "cd -" or, worse, having to type a fully qualified path if your command cd's more than once), but is vital in scripts, where I've found the behaviour of "cd -" to be a little broken at times.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
