Essential Commands for Assessing Storage Conditions:

Below are fundamental commands providing insight into storage devices and their current usage conditions.

• To list available drives in the system along with their mounting directories, use

# lsblk

• To view the current disk usage by the filesystem, including total size, used space, percentage of usage, and mounted directory for each drive, execute:

# df -h 

• To determine the size of a specific directory , utilize:

# du -sh /home

Advanced Commands for Evaluating Storage Conditions:

Disk Usage Summary: Sometimes, it's helpful to get an overall summary of disk usage across the entire system.

• You can use a combination of commands like du, sort, and head to achieve this:

# sudo du -ah / | sort -rh | head -n 20

Ex: sudo du -ah cloudmail/2024-02-06/accounts/ | sort -rh | head -n 20

• Disk Usage with File Types: If you want to analyze disk usage by file types, you can use commands like find along with du

# sudo find /path/to/directory -type f -exec du -h {} + | sort -rh | head -n 20
