I know that find -ctime +1 will find ALL files that have been modified
that are greater than 1 day old and -ctime 1 will find files that are
ONLY 1 day old -ctime -1 mean files that are less than a day old?
Can find actually use this granularity?
ctime is not modification time, it marks the time when a file was created or had its inode changed -- which includes things like renames, moves, and chmod. mtime is modification time.
Just reverse the logic with ! instead of trying to put negative values of time into find; negative values will either match everything or nothing depending on the exact logic involved...
find ! -mtime +1 ...
I have code that does this:
find ${AUDIT_DIR} \( -name "*.txt" -o -name "*.xml" -o -name "*.aud" \) -ctime -1 > /tmp/list.out
Trying to figure out what this does and if the -ctime -1 is needed?
It finds files inside $AUDIT_DIR with the extension xml, aud, or txt. I don't think negative numbers make any sense here -- they're not mentioned in find's documentation, so I think it'd either look for a file changed in the future, or end up as some really old time caused by integer wraparound...
Ask who wrote it what it's intended to do.

that person is not around and it did not make sense to me either (ctime -1) so that is why I asked. I will do some more testing and see where it
leads me
a negative number is ok. negative means excatly what the OP said.
