Unlikely, Apache doesn't think that at all, sh thinks that. sh is invoked by your scripts, not by Apache. The error message from sh means sh encountered the end of an input when it was trying to parse a script: > $ echo -e 'a="hello\n' | sh sh: line 1: unexpected EOF while looking for matching `"' sh: line 2: syntax error: unexpected end of file BTW, I say 'sh', this is only 'sh' on linux boxes, the error message is really from 'bash'. On boxes where 'sh' != 'bash', the error message would be this: > $ echo -e 'a="hello\n' | sh Syntax error: Unterminated quoted string > > What puzzles me is: What is looking for quotes in the first place?

Computer programs, given the same inputs, will generally produce the same outputs. Probably you are not invoking the script with the same environment - if you are invoking as a CGI, that includes all headers, cookies, user agent strings etc. As you could see from my example, this is not an uncommon programming error, it simply comes from non Apache components invoking the shell, and not properly escaping the arguments that they pass to the shell.
