One of the boring task is to clean up data when ever disk usage exceeds the threshold limit. Among the many ways do it, here is the simple usage of Unix find command to delete files older than a year.
find . -type f -mtime +365 -delete
Where -mtime +365 suggests to list files older than 365 days.
or
find . -type f -atime +365 -delete
Where -atime stands for access time which is when the file was last read.
Some more examples
find . -mtime -1 # find files modified less than 1 day ago
find . -mtime 1 # find files modified between 24 and 48 hours ago
find . -mmin +5 -mmin -10 # find files modified between
Usage of -exec option
Here is the simple use case.
I want to find all the files with the name 'latest' in a directory and I want to run 'ls -l' command on the result, since I want to know whether 'latest' is a directory or soft link.
find . -maxdepth 2 -name latest -exec ls -l '{}' \;
Here the
-maxdepth option restrict the search to be conducted 2 levels of directory hierarchy.
The syntax '{}' \; is mandatory, which is tedious.
find . -type f -mtime +365 -delete
Where -mtime +365 suggests to list files older than 365 days.
or
find . -type f -atime +365 -delete
Where -atime stands for access time which is when the file was last read.
Some more examples
find . -mtime 0 # find files modified between now and 1 day ago
# (i.e., within the past 24 hours)
find . -mtime -1 # find files modified less than 1 day ago
# (i.e., within the past 24 hours, as before)
find . -mtime 1 # find files modified between 24 and 48 hours ago
find . -mtime +1 # find files modified more than 48 hours ago
find . -mmin +5 -mmin -10 # find files modified between
# 6 and 9 minutes ago
