This disk usage script is designed to gather information on a Linux devices filesystem.
You can either run a breakdown of a filesystem disk usage or inode usage.
- Filesystem Information Overview
- Largest Directories
- Largest Files
- Volume group space
- Large Open Files
- /home/rack usage
- Filesystem Information Overview
- Storage Device Behind Filesystem
- Top Inode Consumers
- Bytes Per Inode
- Disk space usage
- Elapsed Time (time taken to calculate breakdown)
- Server time as script completion
Usage: disk_usage_check.sh [-f] [-i] [-b] [-h]
-i, --inode Display Inode breakdown
-f, --filesystem <filesystem> Specify a Filesystem
-b, --bbcode Print with bbcode
-h, --help Print help (usage)
$ ./disk_usage_check.sh
