[Libguestfs] [PATCH] Fix shebang in perl scripts
Pino Toscano
ptoscano at redhat.com
Mon Oct 5 14:10:48 UTC 2015
Instead of hardcoding the location of perl (assuming it is installed in
/usr), use /usr/bin/env to run it, and thus picking it from $PATH.
This makes it possible to run these scripts also on installations with
perl in a different prefix than /usr.
Also, given that we want enable warnings on scripts, turn the -w
previously in shebang to explicit "use warnings;" in scripts which
didn't have it before.
