# 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 (` `) instead of a newline (`
|
||
`):
|
||
|
||
`{{command}} | rargs -0 {{command}} {0}`
