[$cv =] Lim::Util::run_cmd $cmd, key => value...

This function extends AnyEvent::Util::run_cmd with a timeout and will also set close_all option.

timeout => $seconds

Creates a timeout for the running command and will try and kill it after the specified $seconds, see below how you can change the kill functionallity.

Using timeout will set $$ option to AnyEvent::Util::run_cmd so you won't be able to use that option.

cb => $callback->($cv)

This is required if you'r using timeout.

Call the given $callback when the command finish or have timed out with the condition variable returned by AnyEvent::Util::run_cmd. If the command timed out the condition variable will be set as if the command failed.

kill_sig => 15

Signal to use when trying to kill the command.

kill_try => 3

Number of times to try and kill the command with kill_sig.

interval => 1

Number of seconds to wait between each attempt to kill the command.

kill_kill => 1

If true (default) kill the command with signal KILL after trying to kill it with kill_sig for the specified number of kill_try attempts.
