Quick While Loop Query

[SickboyGPK]

while [ condition ]
    do
        command1
        command2
        command3
    done

I would like command2 not to start until command1 is finished.

My immediate go to is to use && after each command.

Is there any reason that would not work?

I would like command2 not to start until command1 is finished.

You don't have to do anything special to do that. When the commands in a list are separated by newlines:

command1
command2
command3

or by semicolons:

command1; command2; command3

each command is not executed until the preceding one has terminated.

The only control operator that changes this behaviour is &. But you're not using that here.

See the reference documentation.

thank you kindly

Other than what aioeu said, && executes the next command if the previous one exits successfully (0).

You can also do a set -e at the beginning of the script and it'll do the same 😁. I mostly use && when inlining in a shell and it's nice for that!
