Running multiple sub shell script files from main shell script

Question

i have a main shell script file m1.sh and another two script files s1.sh and s2.sh .

here i am running s1.sh and s2.sh from m1.sh . But the problem is s2.sh starts running only after s1.sh runs completely.

m1.sh looks like below

$cat m1.sh
#!/bin/bash
./s1.sh 
./s2.sh

How can i run s2.sh when s1.sh starts running(i dont want to wait until s1.sh completes)

Answer 1

You can put start them as backgroud process, like

#!/bin/bash
./s1.sh &
./s2.sh &

wait       # wait for all background processes to complete

for logfile in ./s1.log ./s2.log
do
    ... process "${logfile}" as needed
done
