"-atime/-ctime/-mtime" the last time a files's "access time", "file status" and "modification time", measured in days or minutes. Time interval in options -ctime, -mtime and -atime is an integer with optional sign.
* n: If the integer n does not have sign this means exactly n days ago, 0 means today.
* +n: if it has plus sing, then it means "more then n days ago", or older then n,
* -n: if it has the minus sign, then it means less than n days ago (-n), or younger then n. It's evident that -1 and 0 are the same and both means "today".
* Examples:
o Find everything in your home directory modified in the last 24 hours:
+ find $HOME -mtime 0
o Find everything in your home directory modified in the last 7 days:
+ find $HOME -mtime -7
o Find everything in your home directory that have NOT been modified in the last year:
+ find $HOME -mtime +365
o To find html files that have been modified in the last seven days, I can use -mtime with the argument -7 (include the hyphen):
find . -mtime -7 -name "*.html" -print
If you use the number 7 (without a hyphen), find will match only html files that were modified exactly seven days ago:
find . -mtime 7 -name "*.html" -print
o To find those html files that I haven't touched for at least 7 days, I use +7:
find . -mtime +7 -name "*.html" -print
