-
- The newer(1) program is a very good solution to the problem. For
- those who (for whatever reason) do not wish to implement it, there
- is an alternate method using the "make" command.
-
- Make(1) has the "-q" option which causes it to return zero or
- non-zero after checking the dependencies. Here is an example:
-
- if echo "$DEPENDENT:$CONTROL;:" | make -f - -q
- then # The dependent file is up-to-date
- else # The control file is newer that the dependent file
- fi
