Use the `pgrep` command you already have to determine the Process ID and then use that PID with something like https://unix.stackexchange.com/questions/7870 to determine how long that PID has been running and `kill` that PID if it has been running too long.

You could run the python script under control of the `timeout` command, so that it gets killed if it runs for more than an hour.

Rather than using pgrep to find the process, a simpler solution may be to run the Python script under the control of the timeout command (which is part of GNU coreutils). You can then limit the maximum runtime of your Python script to 1 hour:

timeout 1h /home/user/crawler/panel/crawler/scans.py

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
