Understanding Maxdepth Mindepth Depth In Linux Find Command

Table of Contents

 

Find command on Linux is a very powerful tool to search files or directories. We can use maxdepth/mindepth to limit down the search to specific depth levels.

How to Use Depth In Find Command

We can combine two options together to limit the search only between max/min depths. On Centos, there is no option for -depth. We can use -maxdepth n -mindepth n to search files or directories only under n depth level.

Learning Maxdepth and mindepth

The descriptions of maxdepth and mindepth are in the following:

  • maxdepth levels – Descend at most levels (a non-negative integer) levels of directories below the command line arguments. -maxdepth 0 means only apply the tests and actions to the command line arguments.
  • mindepth levels – Do not apply any tests or actions at levels less than levels (a non-negative integer). -mindepth 1 means process all files except the command line arguments.
