+# Perms plugin
+
+Plugin to handle some unix filesystem permissions quickly.
+
+To use it, add `perms` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... perms)
+```
+
+## Usage
+
+> **CAUTION:** these functions are harmful if you don't know what they do.
+
+- `set755`: sets the permission to octal 755 for all given directories and their child directories (by default, starting from the current directory).
+
+- `set644`: sets the permission to octal 644 for all files of the given directory (by default, the current directory), recursively. It will only affect regular files (no symlinks).
+
+- `resetperms` is a wrapper around `set755` and `set644` applied to a specified directory or the current directory otherwise.
+  It will set the permissions to 755 for directories, and 644 for files.
+
+## Reference
+
+- octal 644: _read and write_ for the owner, _read_ for the group and others users.
+- octal 755: _read, write and execute_ permissions for the owner, and _read and execute_ for the group and others users.

+Usage: resetperms [-v] [--help] [--slow] [target]
+
+  target  is the file or directory to change permissions on. If omitted,
+          the current directory is taken to be the target.
+
+  -v      enables verbose output (may be supplied multiple times)
+
+  --slow  will use a slower but more robust mode, which is effective if
+          directories themselves have permissions that forbid you from
+          traversing them.
