in reply to perl's command line snippet which I read from a perl article ( perl tutrous )
I have been known to use perl -pi-DIST -e0 file1 file2 file3....
as a "poor man's change control", to save the "distribution" versions of a Makefile or config file as "Makefile-DIST" and so on. The nice thing about the in-place "non-edit" is that permissions and ownership are retained automatically.
