nextname

Generates a unique filename by counting up a number if the given name already exists

Usage

nextname PATTERN

Prints the next available filename by counting up a number. The first # in the PATTERN will be replaced by the number that is counted up. If there is no # in the pattern, (#) is automatically inserted at the end of the PATTERN (but before any filename extension).

Examples:

nextname file.txt

Prints file (1).txt, or file (2).txt if the first one already exists.

nextname file-#.txt

Prints file-1.txt, or file-2.txt if the first one already exists.

TODO

• Make it possible to escape #s in the PATTERN (so that I can write nextname "file\#\#-#" which becomes file##-1).
• Add the option to have multiple #s next to each other in the PATTERN in order to have the generated number be preceded by zeroes.
