.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
.IR dmenu (1),
.IR test (1)

dwm - dynamic window manager
============================
dwm is an extremely fast, small, and dynamic window manager for X.

Requirements
------------
In order to build dwm you need the Xlib header files.

Installation
------------
Edit config.mk to match your local setup (dwm is installed into
the /usr/local namespace by default).

Afterwards enter the following command to build and install dwm (if
necessary as root):

    make clean install

Running dwm
-----------
Add the following line to your .xinitrc to start dwm using startx:

    exec dwm

In order to connect dwm to a specific display, make sure that
the DISPLAY environment variable is set correctly, e.g.:

    DISPLAY=foo.bar:1 exec dwm

(This will start dwm on display :1 of the host foo.bar.)

In order to display status info in the bar, you can do something
like this in your .xinitrc:

    while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
    do
    	sleep 1
    done &
    exec dwm

Configuration
-------------
The configuration of dwm is done by creating a custom config.h
and (re)compiling the source code.

.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.

.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 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 .
