I almost never delete anything (not on purpose anyway). Having said that, sometimes I do need to find old data on a server and offload it to a NAS. Agedu has been around for ages. It’s a great tool for visually identifying directories on the server containing data that may be ripe for archiving.

Install agedu and a couple of other utilities that may come in handy.

yum -y install agedu telnet coreutils

As a test, run agedo for the /opt filesystem:

agedu --no-cross-fs --progress --scan /opt

Now launch the Web UI to view the report. The syntax below will determine your machine’s primary IP, pick an available port, run the UI without authorization requirements (so only use on the internal network), and automatically kill the Web UI after a minute.

timeout 60 agedu --web --address $(dig +short $(hostname) | head -1):\
$(for port in $(seq 8080 65000); do echo -ne "5" | telnet $(dig +short $(hostname) | head -1) \
${port} > /dev/null 2>&1; [ $? -eq 1 ] && echo ${port} && break; done) --auth none

The Web UI example is below.
