Here's some more code to chew on:
#! /bin/sh
eval '(exit $?0)' && eval 'PERL_BADLANG=x;export PERL_BADLANG;: \
;exec perl -x -S -- "$0" ${1+"$@"};#'if 0;
eval 'setenv PERL_BADLANG x;exec perl -x -S -- "$0" $argv:q;#'.q+
#!perl -w
package Htex::a2ping; $0=~/(.*)/s;[EMAIL PROTECTED],'.';do($1);[EMAIL
PROTECTED]@;__END__+if !1;
# This Perl script was generated by JustLib2 at Wed Apr 23 09:14:13 2003.
# Don't touch/remove any lines above; http://www.inf.bme.hu/~pts/justlib
lintian complains:
E: tetex-bin: shell-script-fails-syntax-check ./usr/bin/a2ping
The script in fact starts fine.
Regards, Frank
