you have asked question for performing housekeeping or identifying
which directory is consuming much space. As a Linux Admin I use below
commands for identifying which directory or file is consuming space or
has large size:
# du -chx --max-depth=1 /tmp
# du -chx --max-depth=1 --block-size=M /tmp | sort -nr | head -5
Note: In above second command option I have used —block-size=M which mean it will highlight only directory or file which has size byte block in MB or Megabyte You can use any size byte block unit as per your requirement like you can use G or GB(Gigabyte).
