[php-src] Issue #8240: Misleading error message on popen() when /bin/sh is missing

Issue: https://github.com/php/php-src/issues/8240 Comment Author: arnaud-lb Yes, this could be a way to fix this. I want to hear from the glibc people before taking a decision. Agreed that the documentation doesn't emphasize enough that popen() actually invokes a shell. As to changing the behavior I don't think it would be a good idea: it could break people's code. I think that currently all exec() variants invoke a shell, except pcntl_exec().
