Show drive names next to their full serial number (and disk info)
Scrap everything and use `gawk` to do all the magic, since it's like the future or something. $ gawk 'match($11, /[a-z]{3}$/) && match($9, /^ata-/) { gsub("../", ""); print $11,"\t",$9 }' Yank out only ata- lines that have a drive letter (ignore lines with partitions). Then strip ../../ and print the output. Yay awk. Be sure to see the alternatives as my initial command is listed there. This one is a revision of the original.

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" }

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Combines an arbitrary number of transparent png files into one file
This one liner; combines all sequentially numbered files; in this example IMG_0001.png to IMG_1121.png by generating the shell script, making the shell script executable and then running the shell script to combine the 1121 png into a single png file named _final.png tested on Mac OS X 10.6.3 with ImageMagick 6.5.8-0 2009-11-22 Q16 http://www.imagemagick.org

know the current running shell (the true)
Return the current shell. It is better than print $SHELL which can sometimes return a false value.

Stripping ^M at end of each line for files

this command example converts to 25 fps subtitles that were originally created for 24 fps movie

sort lines by length

Save man pages to pdf
