I have a bash script called run.sh which launches two python scripts meter_1.py and meter_2.py
#!/bin/sh
./meter_1.py &
./meter_2.py &
When the scripts are running and I search for the PID of the scripts using the command
ps -aux | grep python
The output is
openhab+ 9328 84.0 1.6 25320 16580 pts/0 R 22:23 0:04 python ./meter_1.py
openhab+ 9329 84.6 1.6 25320 16596 pts/0 R 22:23 0:04 python ./meter_2.py
Using the pgrep command I can get the the PID
>pgrep python
9328
9329
However I could have multiple python scripts running and I want to get the process ID name by the script it is running not based on if it is python or not.
For example:
>pgrep python" "./meter_1.py
9328
Is there a functionality for this in pgrep? The following seems to work however it would be nice to get just the process ID back.
>ps -aux | grep python" "./meter_1.py
openhab+ 9328 84.0 1.6 25320 16580 pts/0 R 22:23 0:04 python ./meter_1.py
In ba(sh) you can get the PID of the last started process with $!
so in your run.sh script you can simply use:
#!/bin/sh
./meter_1.py &
echo PID of process1: $!
./meter_2.py &
echo PID of process2: $!
