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.
