Generate an inode report (file count) for Debian, CentOS, cPanel, RHEL, with INODES shell/bash script

Inodes

If you have every used shared hosting, or are involved with the hosting business in any way, you should already know what an inode is. Each time a file is created, uploaded, and so on, an inode is created. This inode stores information like ownership, permissions, etc … basically all the metadata about the file. What is the purpose of limiting the amount of files/inodes? Because each shared host will have many customers on the same server, customers that have excessive amounts of inodes (anywhere from 100,000 to 500,000 and up), can cause a heavy load on the server during backups, general operation, and can be taxing on hard drives. Most of the time excessive amounts of inodes is due to cache scripts installed by the user, catchall email accounts, and normally the customer/user doesn’t even know they exist. Well fear no more, I have created a shell/bash script that will help generate reports, and soon notify you about inode usage…

inodes

is a Shell/Bash script to count and display directory inode (each file) usage, and size.

Features Include:

  • Output full directory report
  • Filter out directories based on inode size
  • Include tree view of directories based on inode size

Upcoming Features:

  • Output report to HTML file
  • Enhanced tree view to support extended depth
  • Watch argument to add cronjob and notify by email

Tree display will allow you show sub-directories in the output that have over a specific number of inodes. So if you want a directory with over 50,000 inodes to display the sub-directories in a tree format, use the -t argument.

Exclude will allow you to exclude directories that are below a specific amount of inodes, therefore creating a smaller output/report.

Installation

wget -O ~/bin/inodes https://raw.smyl.es/inodes/master/inodes
chmod +x ~/bin/inodes

Usage

Directory path is not required. If nothing is provided the present working directory is used.

Argument Example Description
-d inodes -d /path/to/dir Specify path to directory to scan. Optional, will use pwd if not specified.
-t inodes -t 50000 Display tree output for directories with over 50,000 inodes. Optional.
-e inodes -e 100 Exclude directories that are below 100 inodes. Optional

Examples

Output inode report for /my/dir showing tree output for sub-directories on directories over 50000 inodes

inodes -d /my/dir -t 50000

Output inode report for /my/dir showing tree output for sub-directories on directories over 50000 inodes, excluding directories with under 10,000 inodes.

inodes -d /my/dir -t 50000 -e 10000

Output inode report for present working directory without any exclusion or tree output

Troubleshooting

If you get a “inodes: command not found” you need to set the correct path. In installation above we installed into ~/bin/inodes

Check path with this command and make sure the file is in one of those directories:

echo ${PATH}

If not you can export path to your .bashrc file

PATH=~/bin:"${PATH}"
export PATH

And verify

which inodes
