.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
|
||||

|
||||
.B \-b
|
||||
dmenu appears at the bottom of 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

|
||||
dmenu matches menu items case insensitively.
|
||||

||||
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
|
||||

.TP
|
||||
.BI \-w " windowid"
|
||||

|
||||
arrow keys, page up, page down, home, and end.

|
||||
.SH NAME
|
||||
stest \- filter a list of files by properties
|

|
||||
.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

|
||||
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.

.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.
|

||||
.TP
|
||||
.B 0
|
||||
At least one file passed all tests.
|
||||
.TP
|
||||
.B 1
|
