singlerun

Make sure an instance of the currently running script is only instanced once.

singlerun(killother, includeparams, mainProc)

Runs the mainProc if killother is true and is not currently running a script with the same name.

Arguments

• killother boolean that specifies what to do if the script is already running, if true it will send a kill segterm to the other proc.
• includeparams boolean that tells singlerung to consider the arguments of the script as part of the search of a process already running, if false it will just consider the script name; i.e. myscript.js and myscript.js --help would be different if includeparams is true.

examples

singlerun = require("singlerun")

// run script and kill any other instance of same script witouth considering the parameters for uniqueness
singlerun(true, false, function(){
	console.log "hello planet!"
});

// run script if not already running considering the parameters of the script
singlerun(false, false, function(){
	console.log "hello planet!"
});
