Hi

I have script1.pl and script2.sh.

I want to run first script1.pl once it finish the job..Inside script1.pl itself i want to call script2.sh.

So i am planning get pid of script1.pl and using this pid to give wait command to run second script

Below script is not work can anyone please help me for correct script for above usage.

echo "starts to run second script"
wait $$
sh ./script2.sh

I do not really understand that.
simply write:
script1.pl; script2.sh
or even better:
script1.pl && script2.sh

That is what "script1.pl && script2.sh" do. The shell runs the first one (and waits for the child pid to exit) then runs script2.sh, if script1.pl doesn't have an error.

If you want both to run, no matter what, then use "script1.pl; script2.sh".

Hi,

Thing is script1.pl inside have several functions
Input to script1.pl will get it from another script (inputs example 1 2 3)

Say
If it is 1
Then
Run some thing
If it is 2
Then
Run some thing
If it is 3
Then
Run some thing
If it is 3
Then
Run some thing
.
.
.

Suppose input is 2 then i want run script2

Suppose input is 5 then i want run script5

Note script1.pl parallel runs

This is my requirement

That sounds like homework.

You might read the man page on bash. There are a number of programming constructs that allow that.
