in reply to Not equal, regular expressions

Right.

Assume the parameter is "mike.txt". Then the regex will match for .txt, but fail for .htm and .html, so the error will get printed twice.

If the parameter doesn't match any of those patterns, the error gets printed 3 times.

You're also not checking to make sure the extension is at the end of the filename, so that would match "miketxt.exe" as well, since /.txt/ is "any character, followed by 'txt'".

Please check out this discouraging webpage to get some other ideas of ways your script could possibly be abused...

[Corion]: ... entering the data
[Corion]: Discipulus: I don't know whether I could really do that, but the init process itself mostly launches other processes, and the whole startup is just following a path of dependencies and making sure they are all running. Which basically is what ...
[Discipulus]: when at work my time is (temporarly) owned by the firm, so i do not care (coworkers whatch movies.. I code Perl)
[Corion]: ... make already does, except for files instead of programs. But maybe with some /proc hackery, that could be eliminated and one could use plain make :-D
[choroba]: systemd just makes is asynchronous
[choroba]: so, make -j
[Corion]: Discipulus: Yeah - but when writing Perl to save time (instead of having fun), it helps to look whether you're actually saving time ;) Why spend 5 minutes doing manually what you can spend three years automating? ;)
[Corion]: choroba: Oh, yeah :-D
