getparents_by_handle - Linux

Overview

getparents_by_handle is a powerful Linux command used to retrieve the parent directories of a specified handle. It is commonly employed in situations where one needs to quickly identify the hierarchy of a particular directory or file.

Syntax

getparents_by_handle [-f FILE...] [-l] [-p PATH...] [-s] [-v] [DIR...]

Options/Flags

Required:

  • -f FILE…: Specify one or more files or directories for which parent directories need to be retrieved.

Optional:

  • -l: List all parent directories of the specified files or directories.
  • -p PATH…: Provide a list of paths to be ignored when searching for parent directories.
  • -s: Shorten the output by only displaying the last level of parent directories.
  • -v: Display verbose output, showing the full path of each parent directory.

Examples

Example 1: Retrieve parent directory of a file

getparents_by_handle -f /home/user/Documents/myfile.txt

Output:

/home/user/Documents

Example 2: List all parent directories of a directory

getparents_by_handle -l -f /var/log/

Output:

/var
/

Common Issues

  • No output: Ensure that the specified files or directories exist and are accessible.
  • Unexpected output: Check if any ignore paths (-p) are preventing the desired directories from being displayed.
