I tried last two days to run the replace script with my bot ([[es:Ususario Löwenbot]]) like I all the time do to replace text in many articles of a category, for example I write the instruccions:

pwb.py replace -lang:es -regex -putthrottle:1 -catr:"Remeros por país‎‎"

but the tool py.replace gives next error:

bash: pwb.py: command not found

I'm not a programming specialist, I don't understand the answers to the technical problems given here, but I need to run the Tool many times next days. Please, give me a SOLUTION!
