Execute MySQL query send results from stdout to CSV
You can, of course, tell MySQL to output results to a file and dictate how to terminate lines, etc. But sometimes you don't have access to the file system MySQL is running on, complicating outputting your results to a CSV, necessitating either annoying hacks or this simple command :D

Video thumbnail
Faster thumbnail creation than '-itsoffset' $ffmpeg -itsoffset -4 -i test.avi -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 test.jpg

Get the size of all the directories in current directory
OSX's BSD version of the du command uses the -d argument instead of --max-depth.

Fetch the Gateway Ip Address
Better use iproute2 !

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"

switch case of a text file

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" }

Copy all documents PDF in disk for your home directory
I used this to copy all PDFs recursively to a selected dir

grep compressed log files without extracting
accomplishes the same thing without unzipping the whole file, and while i have never seen a log.tar.gz file that was a binary, i will concede that it might happen, so add the -a in there: $zgrep -ia "string" log.tar.gz it's still shorter/easier to type...
