.TH PSTREE 1 "Apr 7, 1996" "Linux" "User Commands"
.SH NAME
pstree \- display a tree of processes
.SH SYNOPSIS
.ad l
.B pstree
.RB [ \-a ]
.RB [ \-c ]
.RB [ \-h ]
.RB [ \-l ]
.RB [ \-n ]
.RB [ \-p ]
.RB [ \-u ]
.RB [ \-G | \-U ]
.RB [ \fIpid\fB | \fIuser\fB]
.br
.B pstree
.RB \-V
.ad b
.SH DESCRIPTION
.B pstree
shows running processes as a tree. The tree is rooted at either
\fIpid\fP or \fBinit\fP if \fIpid\fP is omitted. If a user name is specified,
all process trees rooted at processes owned by that user are shown.
.PP
\fBpstree\fP visually merges identical branches by putting them in square
brackets and prefixing them with the repetition count, e.g.
.nf
.sp
init\-+\-getty
|\-getty
|\-getty
`-getty
.sp
.fi
becomes
.nf
.sp
init\-\-\-4*[getty]
.sp
.fi
.SH OPTIONS
.IP \fB\-a\fP
Show command line arguments. If the command line of a process is swapped out,
that process is shown in parentheses. \fB\-a\fP implicitly disables compaction.
.IP \fB\-c\fP
Disable compaction of identical subtrees. By default, subtrees are compacted
whenever possible.
.IP \fB\-G\fP
Use VT100 line drawing characters.
.IP \fB\-h\fP
Highlight the current process and its ancestors. This is a no-op if the
terminal doesn't support highlighting or if neither the current process
nor any of its ancestors are in the subtree being shown.
.IP \fB\-l\fP
Display long lines. By default, lines are truncated to the display width or
132 if output is sent to a non-tty or if the display width is unknown.
.IP \fB\-n\fP
Sort processes with the same ancestor by PID instead of by name. (Numeric
sort.)
.IP \fB\-p\fP
Show PIDs. PIDs are shown as decimal numbers in parentheses after each
process name. \fB\-p\fP implicitly disables compaction.
.IP \fB\-u\fP
Show uid transitions. Whenever the uid of a process differs from the uid of
its parent, the new uid is shown in parentheses after the process name.
.IP \fB\-U\fP
Use UTF-8 (Unicode) line drawing characters. Under Linux 1.1-54 and above,
UTF-8 mode is entered on the console with \fBecho -e '\\033%8'\fP and left
with \fBecho -e '\\033%@'\fP
.IP \fB\-V\fP
Display version information.
.SH FILES
.nf
/proc location of the proc file system
