A similar effect can be seen with some other parameter combinations such as putting -print in the wrong place - you can get all files in the system printed or none rather than just what you want.

As it is implied by the juxtaposition of two expressions it does not have to be specified. The expression evaluates to true if both expressions are true. The second expression is not evaluated if the first expression is false. -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Unfortunately, that kind of precise operational language blows right by someone with not much experience with such things.That is true of many points of documentation. It often takes some more conversational type language to unlock the official language. jerry -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You might want to list every filename for logging purposes, then do some other processing (-delete maybe, or something called via -exec) on certain other conditions. More manpage pasting: -ls This primary always evaluates to true. The following information for the current file is written to standard output: its inode number, size in 512-byte blocks, file permissions, number of hard links, owner, group, size in bytes, last modification time, and pathname. -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

For starters I don't see -n. I see newer but that seems to compare to
another file.. Is this something you have done in the past?
All I gave you was an example of how negation works, not a specific command
for find.
Try this: find {path} ! -newer {path to file with date you want}
Or you can touch a file with the date you want. Then use that file as the
key for find to know what ! -newer means.
Take a look at this:

There's tons of ways to do what you want. You just need to choose one that
you like.

How do those flags work? +5 = changed during last five days? -5 = newer than five days? From the bottom of the PRIMARIES section of the manpage: All primaries which take a numeric argument allow the number to be preceded by a plus sign (``+'') or a minus sign (``-''). A preceding plus sign means ``more than n'', a preceding minus sign means ``less than n'' and neither means ``exactly n''. I ran it on a directory and was surprised to find that both -5 AND +5 listed a file from February. :-( -5 definitely should not, and doesn't on my system.
