Few tricks I found useful when tinkering with some of my media files. Works under Linux and macOS. (Bash, zsh, etc)
Extract filename from a path, for example
MyFilename="/path/to/my/some_file.mp4"
echo "${MyFilename##*/}"
Results in:
some_file.mp4
The magic is to be found in "##*/"
Extract file extension
MyFilename="/path/to/my/some_file.mp4"
echo "${MyFilename#*.}"
Results in:
mp4
and here the magic is in "#*."
