Rust parallel tries to execute even if regex doesnt match

[Quackdoc]

I send the below list into rust-parallel and execute this command;

rust-parallel.exe -j 4 -r '(.*)\\(.*).(png)' echo `{0`} `|`| `{1`} `|`| `{2`}.jxl

and the output is given below that. It would be nice if the input lines could be sent to a log file or stderr instead

Agree this is a bug, will fix this. Thanks for reporting this!

This is fixed in version 1.13.0

rust-parallel now emits WARN log for input lines that do not match provided regular expression. It will not attempt to run commands for these lines.

Example on macos unix shell where file test contains your file list above:

cat test | rust-parallel -j 4 -r '(.*)\\(.*).(png)' echo '{0} || {1} || {2}.jxl'
