# This is sp, the command-line Spotify controller. It talks to a running
# instance of the Spotify Linux client over dbus, providing an interface not
# unlike mpc.
#
# Put differently, it allows you to control Spotify without leaving the comfort
# of your command line, and without a custom client or Premium subscription.

# Add the following line to your byobu keybindings.tmux file (~/.byobu/keybindings.tmux). 
# This will set the key combo ctrl-a, b (control plus 'a', then 'b') to copy the current byobu/tmux paste buffer to the X/Gnome clipboard.
# This example uses parcellite to manage the X/Gnome clipboard so that, obviously, must be installed too.
# parcellite might be able to be replaced with another tool like xsel but that hasn't been tested yet.

Using strace and lsof to debug blocked processes

You can use strace on a specific pid to figure out what a specific process is doing, e.g.:

strace -fp <pid>

You might see something like:

select(9, [3 5 8], [], [], {0, 999999}) = 0 (Timeout)
