Find out my Linux distribution name and version

find duplicate messages in a Maildir

# find assumes email files start with a number 1-9 # sed joins the lines starting with " " to the previous line # gawk print the received and from lines # sort according to the second field (received+from) # uniq print the duplicated filename # a message is viewed as duplicate if it is received at the same time as another message, and from the same person. The command was intended to be run under cron. If run in a terminal, mutt can be used: mutt -e "push otD~=xq" -f $folder

Resize photos without changing exif

To resize photos without changing exif datas, pretty cool for gps tagging. (Require ImageMagick)

Show linux kernel modules dependencies

Use modprobe to list all the dependencies of a certain kernel module. Handy when debugging system issues.

grep -v with multiple patterns.

Use multiple patterns with grep -v. So you can print all lines in a file except those containing the multiple patterns you specify.

Cut flv video from minute 19 to minute 20 using flvtool2

We should calculate the video duration to milliseconds, 1 minute = 60000 milliseconds

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Recursively unrar into dir containing archive

From the cwd, recursively find all rar files, extracting each rar into the directory where it was found, rather than cwd. A nice time saver if you've used wget or similar to mirror something, where each sub dir contains an rar archive. Its likely this can be tuned to work with multi-part archives where all parts use ambiguous .rar extensions but I didn't test this. Perhaps unrar would handle this gracefully anyway?

re-assign line numbers

LIST FILENAMES OF FILES CREATED TODAY IN CURRENT DIRECTORY

Then pipe to 'xargs ls' for a familiar listing, possibly using find's -print0 and xarg's -0 options.
