I'm trying to run this script on Mac OS 10.7 (Lion) and I'm getting the error:
$ bbcolors
-bash: /usr/local/bin/bbcolors: /usr/bin/env: bad interpreter: Operation not permitted
I've successfully run this script on other Macs of mine. It's just this script downloaded and unmodified from Daring Fireball.
I found this person with a very similar problem but the accepted answer was that the filesystem had a 'noexe' option on mount. I'm pretty sure that's not the case for me because I've just got it in /usr/local/bin/ and other stuff in there works fine (it also doesn't run from other places or as other users including root).
$ which bbcolors
/usr/local/bin/bbcolors
$ ls -l /usr/local/bin/bbcolors
-rwxr-xr-x@ 1 nick staff 9751 Mar 30 19:09 /usr/local/bin/bbcolors
It's a Perl script not a compiled binary, not that that should matter. Here's some extra info for what it's worth:
$ cat /usr/local/bin/bbcolors |head -n 1
#!/usr/bin/env perl
$ which perl
/usr/bin/perl
$ env | grep PATH
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
Did you happen to open/save the file in TextEdit?
That can introduce filesystem metadata (quarantine attribute) leading to the symptom you describe.
Try:
xattr -l /usr/local/bin/bbcolors
and
xattr -d com.apple.quarantine /usr/local/bin/bbcolors
if you see the quarantine attribute.
