Bug#904414: lintian: check for Perl scripts with a shebang not using /usr/bin/perl (Policy 10.4)



Package: lintian
Version: 2.5.93
Severity: wishlist

Debian Policy 10.4 states:

   All command scripts, including the package maintainer scripts inside
   the package and used by dpkg, should have a #! line naming the shell
   to be used to interpret them.

   In the case of Perl scripts this must be #!/usr/bin/perl.

It would be nice if lintian could detect scripts that are Perl scripts
(text/x-perl MIME type or "Perl script text executable" file type) but
do not use the /usr/bin/perl binary in the shebang. While arguments in
shebangs are usually a bad idea, lintian should accept them here:

Debian Policy 10.4 compliant:

#!/usr/bin/perl
#!/usr/bin/perl -T
#! /usr/bin/perl
#! /usr/bin/perl -T

Not Debian Policy 10.4 compliant:

#!/usr/bin/env perl
#!/usr/local/bin/perl
