Run a command without making me wait

I'm a newbie of Shell Script Linux.
I'm working on Automation testing with Android , so I'd like to run some shell script following as bellow:

  1. Start recording screen by adb ( cmd1.sh)
  2. Do the scenario testing then Stop/Save recorded file (cmd2.sh)

Unfortunately , when I run cmd1.sh I MUST wait 3 minute before cmd2.sh is run.
That means I can not record a video :sad:
Here is the my run command content:

run.sh file content:

./cmd1.sh $
./cmd2.sh

cmd1.sh file content:

adb shell screenrecord /sdcard/file.mp4

cmd2.sh file content:

calabash-android run app.apk

Finally, I open terminal then run command :

./run.sh

Of course, video can not save because after cmd1.sh is finished, cmd2.sh is run !!!
Have anybody can help me in this point?
Thank you so much !

Here is the manual step that I can play video recording.
1. OPEN terminal A
2. Run command 1 ( Start recording screen script )
3. Open other terminal B then run a command 2
4. After command 2 finished, go back to Terminal A then Ctrl C .
5. Confirm video in /sdcard/file.mp4 that can play normally

I'm working on MAC OSX Yosemite 10.10.5

Solution

  • Easy Solution: run.sh file content:

    ./cmd1.sh &          # run this command in the background
./cmd2.sh            # run this command to completion 
kill -SIGINT %1      # send the interrupt signal to the first command (ctrl+c)

    Slightly more correct Solution: run.sh file content:

    ./cmd1.sh &            # run this command in the background
recPID=$!              # save the PID for this process for later
./cmd2.sh              # run this command to completion 
kill -SIGINT $recPID   # send the interrupt signal to the first command (ctrl+c)
