  • bash output is inserted into the clipboard, then mousepad is started and the clipboard content is pasted. xsel and xdotool needs to be installed. Instead of the mousepad any other editor can be used. I've successfully tested the Sublime Text Editor and it opens a new tab for each new paste. Check Sample output for a usage example. This command is originated from here - Show Sample Output

    alias 2edit='xsel -b;n=pipe$RANDOM;xdotool exec --terminator -- mousepad $n -- search --sync --onlyvisible --name $n key --window %1 ctrl+v'

  • This command is suitable to use as application launching command for a desktop shortcut. It checks if the application is already running by pgrepping its process ID, and offer user to kill the old process before starting a new one. It is useful for a few x11 application that, if re-run, is more likely a mistake. In my example, x2vnc is an x11 app that does not quit when its connection is broken, and would not work well when a second process establish a second connection after the first broken one. The LC_ALL=C for xmesseng is necessary for OpenSUSE systems to avoid a bug. If you don't find needing it, remove the "env LC_ALL=C" part

    sh -c 'if pgrep x2vnc && env LC_ALL=C xmessage -button "Kill it:0,Ignore it:1" "Another connection is already running. Should I kill it instead of ignoring it?"; then killall x2vnc; fi; x2vnc -passwd /home/Ariel/.vnc/passwd -east emerson:0'

What's this? 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.

Check These Out

Copy sparse files
This causes cp to detect and omit large blocks of nulls. Sparse files are useful for implying a lot of disk space without actually having to write it all out. You can use it in a pipe too: $ dd if=/dev/zero bs=1M count=5 |cp --sparse=always /dev/stdin SPARSE_FILE

Find the package that installed a command

A command's package details
In Debian based distros, this command will list 'binutils' package details which contains 'nm' command. You can replace 'nm' to any other command.

clear MyDNS-ng cache
Occasionally, to force zone updating, cache flush is necessary. This command is better than restart the mydns daemon.

Send multiple attachments using mailx
If you're users have ever asked your script to email their reports in separate attachments instead of tar'ring them into one file, then you can use this. You'll need the mailx package of course. In Unix you'd want to add an additional parameter "-m" (uuencode foo.txt foo.txt; uuencode /etc/passwd passwd.txt)|mailx -m -s "Hooosa!" [email protected]

Factorial With Case
Computes factorials.

Run a file system check on your next boot.
The empty file /forcefsck causes the file system check fsck to be run next time you boot up, after which it will be removed. This works too: $sudo >/forcefsck

backup local MySQL database into a folder and removes older then 5 days backups

Wait for an already launched program to stop before starting a new command.
Referring to the original post, if you are using $! then that means the process is a child of the current shell, so you can just use `wait $!`. If you are trying to wait for a process created outside of the current shell, then the loop on `kill -0 $PID` is good; although, you can't get the exit status of the process.

Watch active calls on an Asterisk PBX
This handles when you have a single call or channel. Other commands will strip out the result if there is a single channel or call active because the output changes the noun to be singular instead of plural.

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.
