Roughly like this (untested).
# func_file_vmtime returns the virtual modification time of a file,
# as a number of seconds since the epoch. (*)
func_file_vmtime ()
{
if test -n "$(git ls-files "$1")" && git diff --quiet HEAD "$1"; then
# file is under version control and is unmodified.
git log -1 --format=%ct "$1"
else
# file has been created or modified by the user.
stat --format=%Y "$1"
fi
}
for file in X1 ... Xn; do
func_file_vmtime "$file"
done | LC_ALL=C sort -n | tail -n 1
(*) To compensate for fractional seconds, 1 second may need to be added
at the end.
Examples:
- Y = po/hello.pot, {X1, ..., Xn} = { po/POTFILES.in, src/hello.c }
- Y = lib/parse-datetime.c, {X1, ..., Xn} = { lib/parse-datetime.y }
- Y = package.tar, {X1, ..., Xn} = $(find package -type f)
