[pacman-dev] Shabang in scripts

This maybe a futile question, but not much to lose here so I'm still asking:
should we let the autotools change the path of the interpreter in the shabang of
the different scripts? (See makepkg and so on.)

Actually, according to


it is said that the interpreter should be /bin/bash, not /usr/bin/bash. The
latter being far less common. Note that the source files are properly set to
/bin/*, only the autotools change them to the realpath of the build system.

This is really a minor issue, but I believe that switching it back to /bin/bash
would remove one portability problem for most systems. For instance, to run
makepkg on a non-Arch system, we download the 'pacman' binary package first,
from which we extract the 'makepkg' and the 'makepkg.conf' files. Since the
package was built on an Arch system, the shabang is set to /usr/bin/bash. On
non-Arch system, we usually need to make to change the shabang back to

What do you think?

Oh, get ahold of yourself.  Nobody's proposing that we parse English.
