Ahhh. Hence the other bit I remembered but couldn't find. There is some trick to put the word perl on the first line in a way it will be ignored. I couldn't remember what it was or why so I left it out and just changed /usr/bin/perl to /bin/sh (the script I quoted from was #!/usr/bin/perl originally) :-(
It is something which people typically put -*- perl -*- or something in but I don't know if that's just because it looks nice, and I can't find any examples around :-(
try something like
#!/bin/sh -f - -- perl and the above
Another alternative - see /usr/bin/texi2html
This program is valid nroff input, etc, but is really a perl script:
=== eval '(exit $?0)' && eval 'exec perl -S $0 ${1+"$@"}' && eval 'exec perl -S $0 $ argv:q' if 0;
'di '; 'ig 00 '; ===
Anyway. There is a userspace solution. Or many of them. And they're portable.
David.
