Incompatibility with sed Command on macOS

[552020]

The codebase contains a sed command that doesn't work uniformly across different operating systems, specifically GNU/Linux and macOS. The incompatibility leads to an error message:

sed: 1: "tmp/errorBash.tmp": undefined label 'mp/errorBash.tmp'

The line in question is in src/test.c, line 108

system("sed -i 's/bash/pipex/g' tmp/errorBash.tmp");

On macOS, the syntax for in-place editing with sed requires an additional argument to specify the file extension for backups.

I fixed it with

system("sed -i '' 's/bash/pipex/g' tmp/errorBash.tmp");

A possible fix would to use preprocessor directives to detect the operating system at compile time and choose the correct syntax accordingly. If I run the test in francinette everything works smoothly.
