Hi, sed has an option `--in-place` to allow the change to a file
in-place. But I don't find a similar option in m4. Does anybody know
there is a similar option that I can use for in-place modification of
a file? Thanks.
No, but you can use the Linux mktemp command and pipe to the temp file then
copy it back.
This does not maintain file mode.
