Description Petr Pisar 2016-01-27 12:40:43 UTC
Created attachment 1118761 [details]
Affected file

Attached Perl script is misrecognized as Minix filesystem:

$ file affected 
affected: Minix filesystem, V2 (big endian), 27749 zones

The script is a new form of a script that was stripped of unneeded "eval 'exec /usr/bin/perl" lines:

--- good        2016-01-27 13:17:41.534000000 +0100
+++ affected    2016-01-27 13:19:44.374000000 +0100

 #!/usr/bin/perl -w
 
-eval 'exec /usr/bin/perl -w -S $0 ${1+"$@"}'
-    if 0; # not running under some shell

 # ----------------------------------------------------------------------
 # urifind - find URIs in a document and dump them to STDOUT.

The longer script is recognized properly:

$ file good affected 
good:     Perl script, ASCII text
affected: Minix filesystem, V2 (big endian)

I have installed file-5.22-6.fc23.x86_64.

Please note that this issue will become a problem because the new form is an output of perl-URI-Find rebuilt in rawhide.

According to Petr, fix for rawhide should be enough:

Feel free to reopen if you find out you need a fix in other Fedora versions too.
