# xe
> Execute a command once for each line piped from another command or file.

- Run a command once for each line of input data as arguments:
`{{arguments_source}} | xe {{command}}`
- Execute the commands, replacing any occurrence of the placeholder (marked as `{}`) with the input line:
`{{arguments_source}} | xe {{command}} {} {{optional_extra_arguments}}`
- Execute a shellscript, joining every `N` lines into a single call:
`echo -e 'a\nb' | xe -N{{2}} -s 'echo $2 $1'`
- Delete all files with a `.backup` extension:
`find . -name {{'*.backup'}} | xe rm -v`
- Run up to `max-jobs` processes in parallel; the default is 1. If `max-jobs` is 0, xe will run as many processes as cpu cores:
`{{arguments_source}} | xe -j {{max-jobs}} {{command}}`
