AllSync
Okay, I hate to admit it, but sometimes I like synchronous methods. Usually when writing one-off administrative scripts, or boot actions.
The fd
module has readFileSync
but so far there is no execSync
.
I wanted a synchronous exec module that has no dependencies.
Usage
AllSync executes the command passed to it,
but synchronously calls the callback with data from stdout
.
allsync = require("allsync");
allsync.exec( "find /", function(data){
process.stdout.write(data);
});
console.log("Done!");
The above will not print Done!
until the child process exits.
Advanced
At this time, AllSync does not capture stderr
,
if you want it you will have to redirect stderr in your command.
allsync.exec( "find / 2>&1", function(data){...});
Finally, AllSync returns with the exit code of the sub process.
var code = allsync.exec( "rm -rf /", function(data){...});
console.log("Child Process Exited with Code %d", code);
