I have a log file. Every line with a specific number I want to sum the last number of this line. To grep and cut is no problem but I don't know how to sum the numbers. I tried some solutions from StackExchange but didn't get them to work in my case.

This is what I have so far:
```bash
grep "30201" logfile.txt | cut -f6 -d "|"
``` 
30201 are the lines I'm looking for.

I wan't to sum the last numbers 650, 1389 and 945

The logfile.txt
