Hi guys and gals. Anyone got an idea for a quick script to split up a
regular LFS style (-Naur) diff file? Ideally, just dump each to it's
own numbered file...trying to save time on OOo-1.1.5.
Hmm, for some reason 'quilt' (http://savannah.nongnu.org/projects/quilt)
comes to mind, though I think that's more of a multiple patch management
tool. You might be able to get away with a shell script that grep's for
the first 'diff -Naur' line, grep's for the second 'diff -Naur' line,
then 'split's the file on those line numbers. Repeat until done!
Or even easier:
======================== 8< =======================
#!/bin/sh
ORIGINAL="$1"
BASE="$2"
NUM=0
SEEN_PATCH=1
exec >"$BASE.header"
IFS=""
while read -r LINE
do
case "$LINE" in
diff*|\+\+\+*|---*)
if [ "$SEEN_PATCH" -eq 1 ]
then
SEEN_PATCH=0
NUM=$(($NUM + 1))
exec >"$BASE.$NUM.patch"
fi
echo "$LINE"
;;
*)
SEEN_PATCH=1
echo "$LINE"
;;
esac
done <"$ORIGINAL"
======================== >8 =======================
Usage:
./split-patch original-big.patch basename-for-pieces
E.g.,
./split-patch ../coreutils-5.2.1-i18n_fixes-1.patch i18n_fixes
This would produce:
i18n_fixes.header
i18n_fixes.1.patch
i18n_fixes.2.patch
...
i18n_fixes.20.patch
