# xargs > Execute a command with piped arguments coming from another command, a file, etc. > The input is treated as a single block of text and split into separate arguments on spaces, tabs, newlines and end-of-file. - Main usage pattern: `{{arguments_source}} | xargs {{command}}` - Delete all files with a `.backup` extension: `find . -name '*.backup' | xargs rm -v` - Convert newlines in the input into NUL (`\0`) characters, and split on those only (useful if the input to xargs contains spaces): `{{arguments_source}} | tr '\n' '\0' | xargs -0 {{command}}` - Execute the command once for each input line, replacing any occurrences of the placeholder (here marked as `_`) with the input line: `{{arguments_source}} | xargs -I _ {{command}} _ {{optional_extra_arguments}}`
