I second that with AWK false positives:
$ cat test.pl
#!/usr/bin/perl -w
BEGIN { print hai }
$ file test.pl
test.pl: awk script, ASCII text
$ head -1 test.pl | file -
/dev/stdin: a /usr/bin/perl -w script, ASCII text executable
$
I have attached the gzip'd output of file -d test.pl.

How can these clearly perl scripts marked as C++ source, ASCII text? Because the C++ patterns override any she-bang detection. And that's a bug. And the she-bang detection for Perl is broken, too *sigh* FWIW, /usr/sbin/grml2usb from your followup is now detected as | a /usr/bin/env python script executable (binary data) Yes, there is binary data in that file: | ^O17^L^X/boot/syslinux/logo.16 Christoph signature.asc Description: Digital signature

Hi, As I checked more for executables on Debian, I found more of the strange file results: /usr/bin/gvfs-less: Palm OS dynamic library data #!/bin/sh $ head -1 /usr/bin/gvfs-less #!/bin/sh /usr/sbin/grml2usb: data $ head -1 /usr/sbin/grml2usb #!/usr/bin/env python /usr/bin/musixtex: LaTeX 2e document, ASCII text $ head -1 /usr/bin/musixtex #!/usr/bin/perl -w /usr/bin/latexmk:TeX document, ASCII text $ head -1 /usr/bin/latexmk #!/usr/bin/env perl All these strange results comes from #!/ started files. The logic to decide should put more values to these #!/, I think... Osamu -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
