Check These Out

Convert files from DOS line endings to UNIX line endings
Here "^M" is NOT "SHIFT+6" and "M". Type CTRL+V+M to get it instead. Its shortest and easy. And its sed!, which is available by default in all linux flavours.. no need to install extra tools like fromdos.

Check syntax of all Perl modules or scripts underneath the current directory
Finds all *.p[ml]-files and runs a perl -c on them, checking whether Perl thinks they are syntactically correct

Get video information with ffmpeg
ffprobe is specially intended to get video information

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

delete all trailing whitespace from each line in file

route output as next command's parameters

A sorted summary of disk usage including hidden files and folders

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" }

Change prompt to MS-DOS one (joke)
This one eliminates the additional backslash at the end (which is not necessary)
