Check These Out

Show directories in the PATH, one per line
quoteless

Convert CSV to JSON

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)

Bork, bork, bork! To keep it short, the first terminal line doesn't show a prompt.

Rename files in batch

Renaming a file without overwiting an existing file name
Sometimes in a hurry you may move or copy a file using an already existent file name. If you aliased the cp and mv command with the -i option you are prompted for a confirmation before overwriting but if your aliases aren't there you will loose the target file! The -b option will force the mv command to check if the destination file already exists and if it is already there a backup copy with an ending ~ is created.
