note IlyaM Either that's a recent feature (and therefore not portable), or hasn't been documented. I think it was there at least since 5.005. There is some mentions of this feature in [cpan://ExtUtils::MM_Unix] (search for fixin) but it seems it is not documented anywhere properly. Where did you find out about this? From personal experience. I just noticed that [ExtUtils::MakeMaker] always replaces my shebang with something else :) For example on my Linux system it replaces existing shebang with <code> #!/usr/bin/perl -w eval 'exec /usr/bin/perl -w -S $0 ${1+"$@"}' if 0; # not running under some shell </code> On Win32 I noticed that [ExtUtils::MakeMaker] does another magic. It creates .bat file which wraps perl script and adds .pl extenstion to perl script when doing its installation. I found that at least on Unix, Unix-like systems and on Win32 systems [ExtUtils::MakeMaker] does the right thing. -- Ilya Martynov, <a href="mailto:ilya@iponweb.net">ilya@iponweb.net</a> CTO IPonWEB (UK) Ltd Quality Perl Programming and Unix Support UK managed @ offshore prices - <a href="http://www.iponweb.net">http://www.iponweb.net</a> Personal website - <a href="http://martynov.org/">http://martynov.org</a> 222457 222586
