.RB [ \-w
.IR windowid ]
.P
.BR dmenu_run " ..."
.SH DESCRIPTION
.B dmenu
is a dynamic menu for X, which reads a list of newline\-separated items from
stdin. When the user selects an item and presses Return, their choice is printed
to stdout and dmenu terminates. Entering text will narrow the items to those
matching the tokens in the input.
.P
.B dmenu_run
is a script used by
.IR dwm (1)
which lists programs in the user's $PATH and runs the result in their $SHELL.
.SH OPTIONS
.TP
.B \-b
dmenu appears at the bottom of the screen.
.TP
.B \-c
dmenu appears centered on the screen.
.TP
.B \-f
dmenu grabs the keyboard before reading stdin if not reading from a tty. This
is faster, but will lock up X until stdin reaches end\-of\-file.
.TP
.B \-i
dmenu matches menu items case insensitively.
.TP
.BI \-l " lines"
dmenu lists items vertically, with the given number of lines.
.TP
.BI \-m " monitor"
dmenu is displayed on the monitor number supplied. Monitor numbers are starting
from 0.
.TP
.BI \-p " prompt"
defines the prompt to be displayed to the left of the input field.
.TP
.BI \-fn " font"
defines the font or font set used.
.TP
.BI \-nb " color"
defines the normal background color.
.IR #RGB ,
.IR #RRGGBB ,
and X color names are supported.
.TP
.BI \-nf " color"
defines the normal foreground color.
.TP
.BI \-sb " color"
defines the selected background color.
.TP
.BI \-sf " color"
defines the selected foreground color.
.TP
.B \-v
prints version information to stdout, then exits.
.TP
.BI \-w " windowid"
embed into windowid.
.SH USAGE
dmenu is completely controlled by the keyboard. Items are selected using the
arrow keys, page up, page down, home, and end.
.TP
.B Tab
Copy the selected item to the input field.
.TP
.B Return
Confirm selection. Prints the selected item to stdout and exits, returning
success.
.TP
.B Ctrl-Return
Confirm selection. Prints the selected item to stdout and continues.
.TP
.B Shift\-Return
Confirm input. Prints the input text to stdout and exits, returning success.
.TP
.B Escape
Exit without selecting an item, returning failure.
.TP
.B Ctrl-Left
Move cursor to the start of the current word
.TP
.B Ctrl-Right
Move cursor to the end of the current word

.TH STEST 1 dmenu\-VERSION
.SH NAME
stest \- filter a list of files by properties
.SH SYNOPSIS
.B stest
.RB [ -abcdefghlpqrsuwx ]
.RB [ -n
.IR file ]
.RB [ -o
.IR file ]
.RI [ file ...]
.SH DESCRIPTION
.B stest
takes a list of files and filters by the files' properties, analogous to
.IR test (1).
Files which pass all tests are printed to stdout. If no files are given, stest
reads files from stdin.
.SH OPTIONS
.TP
.B \-a
Test hidden files.
.TP
.B \-b
Test that files are block specials.
.TP
.B \-c
Test that files are character specials.
.TP
.B \-d
Test that files are directories.
.TP
.B \-e
Test that files exist.
.TP
.B \-f
Test that files are regular files.
.TP
.B \-g
Test that files have their set-group-ID flag set.
.TP
.B \-h
Test that files are symbolic links.
.TP
.B \-l
Test the contents of a directory given as an argument.
.TP
.BI \-n " file"
Test that files are newer than
.IR file .
.TP
.BI \-o " file"
Test that files are older than
.IR file .
.TP
.B \-p
Test that files are named pipes.
.TP
.B \-q
No files are printed, only the exit status is returned.
.TP
.B \-r
Test that files are readable.
.TP
.B \-s
Test that files are not empty.
.TP
.B \-u
Test that files have their set-user-ID flag set.
.TP
.B \-v
Invert the sense of tests, only failing files pass.
.TP
.B \-w
Test that files are writable.
.TP
.B \-x
Test that files are executable.
.SH EXIT STATUS
.TP
.B 0
At least one file passed all tests.
.TP
.B 1
No files passed all tests.
.TP
.B 2
An error occurred.
.SH SEE ALSO

.TH DWM 1 dwm\-VERSION
.SH NAME
dwm \- dynamic window manager
.SH SYNOPSIS
.B dwm
.RB [ \-v ]
.SH DESCRIPTION
dwm is a dynamic window manager for X. It manages windows in tiled, monocle
and floating layouts. Either layout can be applied dynamically, optimising the
environment for the application in use and the task performed.
.P
In tiled layouts windows are managed in a master and stacking area. The master
area on the left contains one window by default, and the stacking area on the
right contains all other windows. The number of master area windows can be
adjusted from zero to an arbitrary number. In monocle layout all windows are
maximised to the screen size. In floating layout windows can be resized and
moved freely. Dialog windows are always managed floating, regardless of the
layout applied.
.P
Windows are grouped by tags. Each window can be tagged with one or multiple
tags. Selecting certain tags displays all windows with these tags.
.P
Each screen contains a small status bar which displays all available tags, the
layout, the title of the focused window, and the text read from the root window
name property, if the screen is focused. A floating window is indicated with an
empty square and a maximised floating window is indicated with a filled square
before the windows title. The selected tags are indicated with a different
color. The tags of the focused window are indicated with a filled square in the
top left corner. The tags which are applied to one or more windows are
indicated with an empty square in the top left corner.
.P
dwm draws a small border around windows to indicate the focus state.
.P
On start, dwm can start additional programs that may be specified in two special
shell scripts (see the FILES section below), autostart_blocking.sh and
autostart.sh. The former is executed first and dwm will wait for its
termination before starting. The latter is executed in the background before
dwm enters its handler loop.
.P
Either of these files may be omitted.

.SH ISSUES
Java applications which use the XToolkit/XAWT backend may draw grey windows
only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
environment variable
.BR AWT_TOOLKIT=MToolkit
(to use the older Motif backend instead) or running
.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
or
.B wmname LG3D
(to pretend that a non-reparenting window manager is running that the
XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
.BR _JAVA_AWT_WM_NONREPARENTING=1 .
.SH BUGS
Send all bug reports with a patch to hackers@suckless.org.

slstatus - suckless status
==========================
slstatus is a small tool for providing system status information to other
programs over the EWMH property of the root window (used by dwm(1)) or
standard input/output. It is designed to be as efficient as possible by
only issuing the minimum of system calls required.
Features
--------
- Battery percentage/state/time left
- Cat (read file)
- CPU usage
- CPU frequency
- Custom shell commands
- Date and time
- Disk status (free storage, percentage, total storage and used storage)
- Available entropy
- Username/GID/UID
- Hostname
- IP address (IPv4 and IPv6)
- Kernel version
- Keyboard indicators
- Keymap
- Load average
- Network speeds (RX and TX)
- Number of files in a directory (hint: Maildir)
- Memory status (free memory, percentage, total memory and used memory)
- Swap status (free swap, percentage, total swap and used swap)
- Temperature
- Uptime
- Volume percentage
- WiFi signal percentage and ESSID
Requirements
------------
Currently slstatus works on FreeBSD, Linux and OpenBSD.
In order to build slstatus you need the Xlib header files.
- For volume percentage on Linux the kernel module `snd-mixer-oss` must be
loaded.
- For volume percentage on FreeBSD, `sndio` must be installed.
Installation
------------
Edit config.mk to match your local setup (slstatus is installed into the
/usr/local namespace by default).
Afterwards enter the following command to build and install slstatus (if
necessary as root):
make clean install
Running slstatus
----------------
See the man page for details.
Configuration
-------------
slstatus can be customized by creating a custom config.h and (re)compiling the
source code. This keeps it fast, secure and simple.

.Dt SLSTATUS 1
.Os
.Sh NAME
.Nm slstatus
.Nd suckless status
.Sh SYNOPSIS
.Nm
.Op Fl s
.Op Fl 1
.Sh DESCRIPTION
.Nm
is a small tool for providing system status information to other programs
over the EWMH
.Em WM_NAME
property of the root window (used by
.Xr dwm 1 ) or standard input/output. It is designed to be as efficient as possible by
only issuing the minimum of system calls required.
.P
By default,
.Nm
outputs to WM_NAME.
.Sh OPTIONS
.Bl -tag -width Ds
.It Fl v
Print version information to stderr, then exit.
.It Fl s
Write to stdout instead of WM_NAME.
.It Fl 1
Write once to stdout and quit.
.El
.Sh CUSTOMIZATION
.Nm
can be customized by creating a custom config.h and (re)compiling the source
code. This keeps it fast, secure and simple.
.Sh SIGNALS
.Nm
responds to the following signals:
.Pp
.Bl -tag -width TERM -compact
.It USR1
Triggers an instant redraw.
.El
.Sh AUTHORS
See the LICENSE file for the authors.
.Sh SEE ALSO
.Xr dwm 1
