It is designed to be as efficient as possible by\nonly issuing the minimum of system calls required.\n\n\nFeatures\n--------\n- Battery percentage/state/time left\n- Cat (read file)\n- CPU usage\n- CPU frequency\n- Custom shell commands\n- Date and time\n- Disk status (free storage, percentage, total storage and used storage)\n- Available entropy\n- Username/GID/UID\n- Hostname\n- IP address (IPv4 and IPv6), interface status\n- Kernel version\n- Keyboard indicators\n- Keymap\n- Load average\n- Network speeds (RX and TX)\n- Number of files in a directory (hint: Maildir)\n- Memory status (free memory, percentage, total memory and used memory)\n- Swap status (free swap, percentage, total swap and used swap)\n- Temperature\n- Uptime\n- Volume percentage\n- WiFi signal percentage and ESSID\n\n\nRequirements\n------------\nCurrently slstatus works on FreeBSD, Linux and OpenBSD.\nIn order to build slstatus you need the Xlib header files.\n\n- For volume percentage on Linux the kernel module `snd-mixer-oss` must be\n loaded.\n- For volume percentage on FreeBSD, `sndio` must be installed.\n\n\nInstallation\n------------\nEdit config.mk to match your local setup (slstatus is installed into the\n/usr/local namespace by default).\n\nAfterwards enter the following command to build and install slstatus (if\nnecessary as root):\n\n make clean install\n\n\nRunning slstatus\n----------------\nSee the man page for details.\n\n\nConfiguration\n-------------\nslstatus can be customized by creating a custom config.h and (re)compiling the\nsource code. This keeps it fast, secure and simple.\n" }, { "path": "arg.h", "content": "/* See LICENSE file for copyright and license details. */\n#ifndef ARG_H\n#define ARG_H\n\nextern char *argv0;\n\n/* int main(int argc, char *argv[]) */\n#define ARGBEGIN for (argv0 = *argv, *argv ?
