I have a script (activate.sh) that checks for a running python script and, if not found, restarts it
#!/bin/bash
ps auxw | grep my_script | grep -v grep > /dev/null
if [ $? != 0 ]
then
echo "Process is not running."
source /path/to/venv/bin/activate #start python environment
export PYTHONUNBUFFERED=yes #to allow for running log output
python /path/to/my/script/my_script.py >> /path/to/my/script/logs/output.log &
fi
This seems to be a pretty basic script template found online for restarting a failed service.
I then set it up on crontab to run every minute.
However, for some reason, the script is only detecting the service (the grep line) if I run it in the local directory that it is in.
If I run /my/path/to/script/activate.sh (from my home directory), nothing
and crontab is not starting the service either
bash grep cron python

Are you sure it'sgrepthat's failing? Can you run the python script from a different path from the command line?

compare grep outputs inside and outside the directory to rule it out

@choroba - yes, I can run the python script. It's in this section here: ps auxw | grep my_script | grep -v grep > /dev/null if [ $? != 0 ] then because the 'echo "Process is not running."' doesn't print out

Please usepgrepinstead of trying to get theps|greppipeline working correctly. Does the Python script itself rely on being started with a particular working directory?

Please use
pgrep instead of trying to get the ps|grep pipeline working correctly. Does the Python script itself rely on being started with a particular working directory?– Kusalananda
