  • Add this to a fiend's .bashrc. PROMPT_COMMAND will run just before a prompt is drawn. RANDOM will be between 0 and 32768; in this case, it'll run about 1/10th of the time. \033 is the escape character. I'll call it \e for short. \e7 -- save cursor position. \e[%d;%dH -- move cursor to absolute position \e[4%dm \e[m -- draw a random color at that point \e8 -- restore position.

    PROMPT_COMMAND='if [ $RANDOM -le 3200 ]; then printf "\0337\033[%d;%dH\033[4%dm \033[m\0338" $((RANDOM%LINES+1)) $((RANDOM%COLUMNS+1)) $((RANDOM%8)); fi'

Check These Out

Show Directories in the PATH Which does NOT Exist
I often need to know of my directory in the PATH, which one DOES NOT exist. This command answers that question * This command uses only bash's built-in commands * The parentheses spawn a new sub shell to prevent the modification of the IFS (input field separator) variable in the current shell

Backup with versioning
Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by the excellent EVACopy http://evacopy.sourceforge.net

Find files with lines that do not match a pattern
This one would be much faster, as it's only one executed command.

Open screen on the previous command
I often find myself wanting to open screen on whatever command I'm currently running. Unfortunately, opening a fresh screen session spawns a new bash session, which doesn't keep my history, so calling screen directly with the previous command is the only way to go.

Check a server is up. If it isn't mail me.
This version uses netcat to check a particular service.

Remount root in read-write mode.
Saved my day, when my harddrive got stuck in read-only mode.

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)
Friday is the 5th day of the week, monday is the 1st. Output may be affected by locale.

Automator Bash script to create Clean zips in MacOS Finder without __MACOSX metadata
Finder compresses to ZIP but always includes extraneous metadata files (__MACOSX and .DS_Store) files and folders that may confuse other programs. One alternative is creating them and then editing the ZIP. This can work standalone or in an automator script accepting multiple selections (files or folders) and creating one zip per argument/selected file without that metada.
