Your boss came to you and asked for total size of files which has not been accessed for more than 30 days! Assume that you are just checking for 1 directory “/abc” . Here comes the simple command:
find /abc -atime +30 -exec ls -lk ‘{}’ \; | awk ‘{SUM += $5} END {print SUM} ‘
Explaination:
find /abc -atime +30 -exec ls -lk ‘{}’ \
find command will find /abc and check for accestime which has not been access for 30 days and list it out the result
awk ‘{SUM += $5} END {print SUM} ‘
awk will sum all the result then only print out final figure.
The command is extremely useful especially you have multiple of directory residing in /abc :
/abc/123
/abc/456
/abc/789
Just write a simple script to generate it! I will cover this on next post.
Just what I need. Thank you !
