Do something based on echo text

Question

I am using shelljs to git clone in my node app. I want to only do something once the clone is successful. So wanted to so something like this:

shell.exec(`git clone https://myrepo.git; echo "cloned"`);

This returns cloned once my repo is cloned on Google Cloud functions. How do I do something like this:

if echo === 'cloned' {
   //do something
} else {
      //do something else
}

It would probably be simpler to just chain your commands. WIth `git clone https://myrepo.git && echo "cloned"`, the `echo` will not be executed if `git clone` returns an error. — Romain Valeri, Dec 06 '22 at 16:32
@RomainValeri, can you give me an example please? Sorry, I am new to this. — nb_nb_nb, Dec 06 '22 at 16:32
This probably is a valuable starting point for you to read about how to use that function: https://stackabuse.com/executing-shell-commands-with-node-js/ — arkascha, Dec 06 '22 at 18:19
I would like to point out that you need to add a test condition on the return code for the git command, to make sure that it was successful. You shouldn't send that "cloned" echo unless it was a fully cloned branch, not act when git terminates badly. — Eric Marceau, Dec 08 '22 at 02:45

use && instead of ; like this:

shell.exec(`git clone https://myrepo.git && echo "cloned"`);

&& means echo "cloned" won't be executed until git clone https://myrepo.git finish successfully.

I ended up using this:

if (shell.exec(`git clone https://myrepo.git`).code === 0) {
    //do something
} else {
   //do something else
}

This worked perfectly.
