I run a python shell from crontab every minute:
* * * * * /home/udi/foo/bar.py
/home/udi/foo has some necessary subdirectories, like
/home/udi/foo/bar.py refers to.
The problem is that
crontab runs the script from a different working directory, so trying to open
Is there a nice way to tell the script to change the working directory to the script's own directory? I would fancy a solution that would work for any script location, rather than explicitly telling the script where it is.
Was the most compact elegant solution. Thanks for your answers and explanations!
This will change your current working directory to so that opening relative paths will work:
import os os.chdir("/home/udi/foo")
However, you asked how to change into whatever directory your Python script is located, even if you don't know what directory that will be when you're writing your script. To do this, you can use the
import os abspath = os.path.abspath(__file__) dname = os.path.dirname(abspath) os.chdir(dname)
This takes the filename of your script, converts it to an absolute path, then extracts the directory of that path, then changes into that directory.
You can get a shorter version by using
As initialized upon program startup, the first item of this list,
path, is the directory containing the script that was used to invoke the Python interpreter
