| # Wrapper script to help parallelize batches of ffmpeg conversions to a single output format | |
| # For example, it can convert all your mp4 files to mp3 format in parallel (or any other formats ffmpeg supports) | |
| # By Nicolas Chan (MIT Licensed) | |
| # Usage: ./convert.sh FORMAT [INPUT_FILES...] | |
| # Example usage: ./convert.sh mp3 *.mp4 | |
| # Dependencies: |
| setuid (s) | setgid (s) | sticky (t) | |
|---|---|---|---|
| Directory | ignored | New subfiles inherit group | Only owner of subfile can (re)move it* |
| File | Executes as file owner | Executes as group | ignored |
Sticky bit can be set with chmod as the first of four digits, or using {+,-}s (for setuid/setgid) and {+,-}t (for sticky). For example, to enable setuid,
chmod u+s $FILE # Add setuid to a file
chmod 4755 $FILE # Possible permissions of /bin/ping
