How to find the % of disk space used by a directory using du command in linux.
You need to use a combination of df (file system) and du (file space usage). Just one of these commands won't do.
#!/usr/bin/env bash mydir="/home/user/Downloads" totalSize=$(du -s -k $mydir | cut -f1) fileSystemSize=$(df --output=size $mydir | tail -1) pct=$(echo "scale=2;($totalSize/$fileSystemSize)*100" | bc -l ) echo "$mydir is $pct"%""
Is this what you are looking for?
/home/user/Downloads is 12.00%
