zargs

A rewrite of xargs in Rust, for fun and science

Todo list

Parameters implemented from xargs:

• "Args file" ie. "Read items from file instead of standard input."
• "Delimiter" ie. "Input items are terminated by the specified character."
• "Replace" ie. "Replace occurrences of a string in the initial-arguments with names read from standard input."
• "max-procs" ie. "Run up to max-procs processes at a time; the default is 1." uses Rayon for parallelization

Not sure if I can about other parameters! Maybe I can be convinced otherwise.

Installation

cargo install zargs

Example Usage

Replacing strings, in the target command, with piped arguments

echo Vasilios | zargs -r name echo "Hello, name!"
Hello, Vasilios!

Should work on Windows!

echo "write-output 'hello world :)'" | zargs powershell
hello world :)
