Note that next jumps to the continue block at the end of the foreach loop. Right at the start of the foreach loop, an undefined parameter is treated like an empty string and simply returns ''. The very first explaining comment is this: Did you notice something? There is also a commented version of that script at. There is a script that tries to find the version of your bourne compatible shell. With that out of the way, let's assume some bourne shell.Ī 7th edition Bourne shell surely is a bourne shell, right? So, as stated by the author, you should not expect the result values of the various functions to be compatible with anything but bourne shells. The Almquist shell variants are very similar to bourne, but not exactly: The korn shells obviously aren't bourne shells, either. Quite obviously, neither from DOS and Windows nor cmd.exe from Windows are even vaguely similar to a bourne shell. Also, not every default shell is a bourne shell. īourne is a large family of shells, but not every shell is a bourne shell. The module clearly states in "Bugs" that. So, let's have a look at the source code of String::ShellQuote version 1.04, dated. While true, that's not a problem with shell_quote. The all seemed centered around the idea of avoiding the shell is better. You seem to allege some problem with shell_quote, but none of the linked post identify one. This bash script is later used by users (this means that I don't want to actually run those commands when my utility runs, rather just to generate the script).Īnd, in an answer to a previous bashing, ikegami stated: My Perl utility generates a bash script that consists of mkdir/rsync/cp commands. The problem boils down to generate a shell script from perl that will be run by different a user, perhaps on a different computer: Now, ovedpo15 came up with a problem that looks like a good reason to have a module like String::ShellQuote, and choroba proposed String::ShellQuote. Most times, it was because the module promises to solve a problem that simply disappears completely if you avoid the shell. Re^2: Passing values from Perl script to shell script.Re^2: preserve quotes after $0 interpolation.I have bashed String::ShellQuote several times:
