Checking Disk Usage Examples

Point 1: To check and list disk usage of /var/log directory is given below

# du -hx /var/log --max-depth=1
0 /var/log/ntpstats
57M /var/log/sa
288K /var/log/tuned
39M /var/log/audit
0 /var/log/chrony
112K /var/log/xcat
3.2M /var/log/anaconda
0 /var/log/rhsm
12K /var/log/Lenovo_Support

Point 2: Sort out and list disk usage in /var/log is given below

# du -hx /var/log --max-depth=1 |sort -h
0 /var/log/chrony
0 /var/log/ntpstats
0 /var/log/rhsm
12K /var/log/Lenovo_Support
112K /var/log/xcat
288K /var/log/tuned
3.2M /var/log/anaconda
39M /var/log/audit
57M /var/log/sa
108M /var/log

Point 3: Show last modification time and sort it by usage

# du -hx /var/log -d 1 --time -a --max-depth=1 |sort -h
