I have a question for you about file mtime(modify
time) on linux. Does the mtime stamp of a file change
as soon as a process starts modifying the file or does
it change it after the change is done?
The reason I am interested in this is that I am
writing a perl script which is supposed to monitor a
file for changes and as soon as the change is done run
another script which processes the changed file. I
the second script to run before the file change is
complete(Which would happen if the mtime changes as
soon as the modification starts).
So how would I check that the file change is done?One
way would be to keep checking in a loop if the mtime
changed if it did goto sleep and check again after a
few seconds, keep repeating this until the mtime stop
changing. But in my opinion this is a stupid way of
doing this so I am hoping one of you has a better way
of doing it.
Thanks for the help.
