SYNOPSIS

pstree [-Uw] [-f file] [-g n] [-l n] [-p pid] [-s string] [-u user] [rootpid ...]

DESCRIPTION

Tree sorted output frontend for ps(1). pstree uses the output of the ps(1) program to show nicely formatted process family trees.

For each rootpid argument, pstree shows one tree rooted at that process. By default, if no rootpid argument is given, it shows a single tree rooted at process 1.

The options are as follows:
-f file
  Read input from file instead of running "ps -kaxwwo user,pid,ppid,pgid,command". If file is a single dash ('-'), pstree reads from standard input.
-g n Use graphics chars for tree. n = 1: IBM-850, n = 2: VT100, n = 3: UTF8.
-l n Show a maximum of n levels.
-p pid Show only parents and descendants of the process pid.
-s string
  Show only parents and descendants of processes containing the string in their commandline.
-U Do not show branches containing only root processes.
-u user
  Show only parents and descendants of processes of user.
-w Wide output, not truncated to terminal width.

ENVIRONMENT

COLUMNS
  The width of the terminal in characters. This can be set with stty 1 columns number.

EXIT STATUS

EXAMPLES
