warnpkg: tell what files a package is going to overwrite

Simple enough: it looks at the files in the tarball and sees what will be overwritten when you installpkg the thing. It also digs around in install/doinst.sh to see what links are going to be removed, like installpkg -warn does.

(Of course, the doinst.sh script could do some crazy stuff that this script won't detect. You'll have to take your chances.)


Run it with a given package name and it'll tell you what will be overwritten:

$ warnpkg fvwm-2.5.23-i686-1beej.tgz
Existing files that will be affected are (*** means rm -rf!):
   /usr/bin/fvwm2 [***]
   /usr/bin/xpmroot [***]
   /usr/man/man1/fvwm2.1.gz [***]
   /usr/man/man1/xpmroot.1.gz [***]
   /usr/libexec/fvwm/2.5.23/FvwmAudio [***]
   /usr/lib/X11/fvwm2 [***]

$ warnpkg wxgtk-2.6.3-i686-1beej.tgz
No existing files will be overwritten.

Then stick it in your PATH someplace. :)
