net_monitor

Monitors internet connection and notifies when it's down/up.

gcc -o noled noled.c

check_fullscreen (X11)

Checks if the current window is full screen and returns true/false.

Build:

Runs a command when the mouse hits the screen corner.

Usage:

./hotcorner --top-left "notify-send 'topleft'" --top-right "notify-send 'topright'"

wmclass (X11)

Prints out window class/instance in the following format:

WM_CLASS=CLASS
WM_INSTANCE=INSTANCE

Build:

gcc -o wmclass wmclass.c -lX11

Reads from stdin and outputs unique lines without sorting. (or just use: awk -v OFS="\n" '!x[$0]++')

• Requires uthash.
