What does BSD sed currently do? I am assuming it leaves a backup file(s) but can you clarify the numbers and names of these?
On Mac OS X (Man page is from FreeBSD, so I believe it would be the same there): sed -i -e 's/foo/bar/' filename will create a backup file named filename-e sed -i -e 's/foo/bar' -e '/asd/dsa/' filename will give an error message because sed -i 's/foo/bar' filename will give an error message sed -i '' 's/foo/bar/' filename will work without creating a backup file, but fails on GNU/sed It's really annoying that BSD sed doesn't like sed -i'' and GNU/sed doesn't like sed -i '' This patch changes the way that sed inplace is run in makepkg when running in versionpkg mode. Previous, sed would run with no backup file, called in the GNU way. It seems there is no cross platform method of calling sed inplace with no backup (BSD/sed uses sed -i '', GNU/sed uses sed -i'' or simply sed -i). Instead, this patch creates a backup file (.pkgsave) and removes it after the succesful completion of the sed operation. This means the user should not see the backup file, unless something went run (full hard drive?) in which case they don't lose the PKGBUILD as they would have before.
