mmv

mmv [options] from to

mmv performs mass file moves, copies, appends, and links using shell-like wildcard patterns. It matches source files with a from pattern containing wildcards, then constructs target names using a to pattern where #1, #2, etc. refer to the text matched by each wildcard in the source pattern.Special substitutions in the target pattern include #l and #u for lowercase and uppercase conversion. The tool plans all operations before executing, detecting and resolving collisions and cycles.

Pattern syntax differs from standard shell globbing. Always preview with -n before executing. Quoting patterns is essential to prevent shell expansion.
