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.

pretend to be busy in office to enjoy a cup of coffee

Dialog's gauge widget accepts progress updates on stdin. This version runs dialog once and updates it every second. There's no need to use timeout which causes screen flicker since it restarts dialog for each update.

Live stream a remote audio device over ssh using only ffmpeg

Change parameter 'plughw:0,0' in accordance with your audio device. To learn 'plughw' option, type the command aplay -l.

Create a new file

resize all JPG images in folder and create new images (w/o overwriting)

Convert all jpegs in the current directory into ~1024*768 pixels and ~ 150 KBytes jpegs

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Delay execution until load average falls under 1.5

If shell escaping of the command is problematic, you can write the command to a file first: $ batch

Show (only) list of files changed by commit

Lists ONLY the files changed by the given HASH/HEAD/list of hashes, etc. The message, commit ID, author, etc. is not included

read manpage of a unix command as pdf in preview (Os X)

Benchmark SQL Query

Benchmark a SQL query against MySQL Server. The example runs the query 10 times, and you get the average runtime in the output. To ensure that the query does not get cached, use `RESET QUERY CACHE;` on top in the query file.

Adding Prefix to File name

Good old bracket expansion :-) For large numbers of files, "rename" will spare you the for-loop, or the find/exec...
