Troubleshooting
Common pitfalls
xargs: illegal option -- I
Solution: Ensure you're using valid options compatible with the installed version of xargs.
xargs: command not found
Solution: Verity command specified is installed and accessible in the PATH.
xargs: input line too long
Solution: Check the maximum line length in the input; potentially split it.
