# rargs
> Execute a command for each line of standard input.
> Like `xargs`, but with pattern matching support.
> More information: <https://github.com/lotabout/rargs>.
- Execute a command for every line of input, just like `xargs` (`{0}` indicates where to substitute in the text):
`{{command}} | rargs {{command}} {0}`
- Do a dry run, which prints the commands that would be run instead of executing them:
`{{command}} | rargs -e {{command}} {0}`
- Remove the `.bak` extension from every file in a list:
`{{command}} | rargs -p '(.*).bak mv {0} {1}`
- Execute commands in parallel:
`{{command}} | rargs -w {{max-procs}}`
- Consider each line of input to be separated by a NUL character (`\0`) instead of a newline (`\n`):
`{{command}} | rargs -0 {{command}} {0}`
