PSTREE(1) General Commands Manual PSTREE(1) NAME pstree -- list processes as a tree 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 sin- gle 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 The pstree utility exits 0 on success, and >0 if an error occurs. EXAMPLES Show branches of processes containing "httpd" using VT100 graphic chars: $ pstree -g 2 -s httpd Show process number "15495" and its descendants: $ pstree 15495 Show process number "15495" and its parents and descendants: $ pstree -p 15495 SEE ALSO ps(1), top(1) AUTHORS The program was written and is maintained by Fred Hucht <fred@thp.uni-due.de>, and this manual page was initially set up by Sebastian Stark.
