disk-usage

Disk Usage Skill Use this skill to analyze disk space and filesystem usage on Linux systems. Quick Start Run the included script for a disk usage overview: ./scripts/diskinfo.sh Manual Commands Filesystem Overview df -h - Disk space usage for all mounted filesystems (human-readable) df -i - Inode usage (number of files) lsblk - Block device tree (disks, partitions) mount - Currently mounted filesystems Directory Size Analysis du -sh /path - Total size of a directory du -h --max-depth=1 /path - Size of immediate subdirectories du -ah /path | sort -rh | head -20 - Largest files/directories Finding Large Files find /path -type f -size +100M - Files larger than 100MB find /path -type f -size +1G - Files larger than 1GB ls -lhS /path | head -20 - List files sorted by size (largest first) Disk Information cat /proc/partitions - Partition table cat /proc/mounts - Mount information stat -f /path - Filesystem statistics Tips Always use -h for human-readable sizes The du command can be slow on large directories Use --max-depth=1 to limit recursion depth Root filesystem ( / ) usage above 90% may cause issues
