I know that perlrun states this : If the C<#!> line does not contain the word "perl", the program named after the C<#!> is executed instead of the Perl interpreter. This is slightly bizarre, but it helps people on machines that don't do C<#!>, because they can tell a program that their SHELL is F</usr/bin/perl>, and Perl will then dispatch the program to the correct interpreter for them. That feature can be questioned, esp. for Unix-like platforms, but it's not my point there; if I look at the code that execs the program specified on the #! line, I see that it also looks for the characters "indir" there. And indeed, that disables the exec : ~§ cat sb.pl #!/bin/cat print "version $]\n"; ~§ perl sb.pl #!/bin/cat print "version $]\n"; ~§ cat sb2.pl #!/bin/cat indir print "version $]\n"; ~§ perl sb2.pl version 5.014001 According to git-blame, this has been this way forever, and it's not documented. Any idea why this could have been included there by Larry ? Personally I wouldn't object to the removal of this exec feature. But at the very least shouldn't we document that "indir" thing ?Thread Next
