I just realized that (unless the script exits prematurely) the
"modification" time will always change, regardless if the file really got
modified, since we do an analogue of
{{{
#!sh
sed ... file.orig > file.new
mv -f file.new file.orig
}}}
(Using the unfortunately non-POSIX {{{-i}}} (in-place) option of {{{sed}}}
would avoid this...)
Should we do
{{{
#!sh
if diff file.orig file.new >/dev/null; then
rm -f file.new # just clean up
else
mv -f file.new file.orig
fi
# or, in short form:
diff file.orig file.new >/dev/null && rm -f file.new || mv -f file.new
file.orig
}}}
? ;-)
Dave, how do your ''"Sage programmer's How to work around non-portable
non-POSIX commands, options and built-in shell functions"'' wiki pages
fare?
