[comp.unix.questions] change vs modify

evan@pedsgo.UUCP (01/22/87)

We are working on our backup scripts, and have found that ff has -c and -m
options, where c=file changed date, and m=file modified date.  In my
dictionary, change and modify are synonyms.  What is the difference to ff
and, I suppose, to all of Unix?

In this case, the difference between a `change' and a `modification'
is the difference between altering the label on a package and
altering its contents.  If someone says `chmod a-w myfile', that
is a change; if someone says `echo foo >> myfile', that is a
modification.
