xe

Execute a command once for each line piped from another command or file. More information: https://github.com/leahneukirchen/xe.

• 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 -N2 -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
