I need in node.js function
result = execSync('node -v');
that will synchronously execute the given command line and return all stdout’ed by that command text.
ps. Sync is wrong. I know. Just for personal use.
UPDATE
Now we have mgutz’s solution which gives us exit code, but not stdout! Still waiting for a more precise answer.
UPDATE
mgutz updated his answer and the solution is here 🙂
Also, as dgo.a mentioned, there is stand-alone module exec-sync
UPDATE 2014-07-30
ShellJS lib arrived. Consider this is the best choice for now.
UPDATE 2015-02-10
AT LAST! NodeJS 0.12 supports execSync natively.
See official docs
