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.

.Dd 2023-04-23
.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
