Re-emerge all ebuilds with missing files (Gentoo Linux)

Revised approach to and3k's version, using pipes and read rather than command substitution. This does not require fiddling with IFS when paths have whitespace, and does not risk hitting command-line size limits. It's less verbose on the missing files, but it stops iterating at the first file that's missing, so it should be definitely faster. I expanded all the qlist options to be more self-describing.
This is sample output - yours may be different.

emerge -av1 `qlist --installed --nocolor | uniq | while read cp; do qlist --exact $cp | while read file; do test -e $file || { echo $cp; echo "$cp: missing $file (and maybe more)" 1>&2; break; }; done; done`

Re-emerge all ebuilds with missing files (Gentoo Linux)

This loops through all installed ebuilds and checks if every file that should be installed is still there and if not adds it to emerge. It includes a verbose output to stderr too. If you have packages installed that have whitespace in their filenames you have to change the IFS to "newline".
This is sample output - yours may be different.

emerge -av1 $(for e in `qlist -I --nocolor | uniq`; do for f in `qlist -e $e`; do if test ! -e $f; then echo $e; echo $e: missing $f 1>&2; fi; done; done)

Losslessly rotate videos from your phone by 90 degrees.

Takes all the .3gp files in the directory, rotates them by 90 degrees, and saves them in the lossless ffv1 encoding. If this rotates in the wrong direction, you may want transponse=1 Re-encoding to ffv1 may result in a significant increase in file size, as it is a lossless format. Other applications may not recognize ffv1 if they don't use ffmpeg code. "huffyuv" might be another option for lossless saving of your transformations. The audio may be re-encoded as well, if the encoding used by your 3gp file doesn't work in a avi container.

Random unsigned integer

display systemd log entries for sshd using "no-pager" (a bit like in pre-systemd: grep sshd /var/log/messages)

In pre-systemd systems, something like: "# grep sshd /var/log/messages" would display log events in /var/log/messages containing "sshd". # journalctl -u sshd --no-pager The above command displays similar results for systemd systems. (Note that this needs to be run with root permissions to access the log data.)

Get absolut path to your bash-script

Another way of doing it that's a bit clearer. I'm a fan of readable code.

This function will encrypt a bash script and will only execute it after providing the passphrase. Requires mcrypt to be installed on the system.

Verify/edit bash history command before executing it

Bash history commands are those that begin with the character ! (eg. the most popular 'sudo !!' Explained here => http://www.commandlinefu.com/commands/view/13). By default bash immediately executes the history command. Setting this shell option will make bash first allow you to verify/edit an history command before executing it. To set this option permanently, put this command in ~/.profile or ~/.bashrc file. To unset this option issue following command. $shopt -u histverify
