Shell Programming and Scripting

hey mates,

I was wondering if someone could assist me with this one, I have couple scripts that I would like to invoke from .sh ( One after another )

Script1
Script2
Script3

Is it possible to run script 2 after script one finished running ? And again start script 3 after script 2 finished running ...

Does it make any sense

Help would be highly appreciated.

Perhaps I don't understand your questions, but these three lines in a row would seem to do what you want:

Code:

./script1.sh
./script2.sh
./script3.sh

Or all on one line:

Code:

./script1.sh ; ./script2.sh ; ./script3.sh

If that's not what you want, then what do you want?

Let me try to rephrase this,

I have one script lets call it script1.sh

And this script includes multiple commands inside

I would like to run those commands 1 at the time after one command is done it work I would like to execute 2nd one and then 3rd one etc....

I don't want to run them all at the same time because that would be overkill for the system.

thank you again

That's exactly what you said before, and exactly what my examples do.

Try

Code:

sleep 1
echo a
sleep 1
echo b
sleep 1
echo c

it runs them in order, waiting for the previous ones to end.

Thank you,

So I assume that I have to put sleep 1 in front of each command ??
and what about echo ?

sleep and echo have nothing to do with it. It's just an example.

Did you try my example, and see what it did?

The shell runs lines in order. That's why it waits a second between printing A, B, and C -- sleep pauses a second, and the shell waits for it to end before running the next line.

If you left out all the sleeps it'd still run all three commands in order and wait for each to finish. But it'd happen so quickly you wouldn't see what it was doing.

Got it Thx !
