vi a remote file
notice the double slash

kill all foo process
Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command. Works on almost every Linux/Unix platform I have tried.

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" }

Who invoked me? / Get parent command
Get the name of the parent command. This might be helpful, if you need to react on that information. E. g. a script called directly via ssh has got sshd as parent, manually invoked the parent process will probably be bash

Search some text from all files inside a directory

Get Shellcode from ARM Binaries
Getting shellcode from ARM binaries - @OsandaMalith

Get current Xorg resolution via xrandr
Not sure if it works the same on any shell.

Convert PDF to JPEG using Ghostscript
Converting your PDF file to JPEG images. You can set resolution by -r option (default: 72dpi).

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"

Grep colorized
Highlights the search pattern in red.
