Removing the unwanted data from a file

[ndc85430]

I've done a grep search through all these emails and folders. The output is in a file. The data is like this

family/Smallville, Robert & Mary/28134: Bioelectro healing - https://t.me/bioelectromagnetic_healing

All I want is the URI, so that I'm left with

https://t.me/bioelectromagnetic_healing

I haven't looked at all your cases, but why even bother with Python for this? AWK is a great little language for text processing things like this. It breaks lines into fields, which by default are separated by spaces and indexed from 1. Hence

Output:
$ echo "family/Smallville, Robert & Mary/28134: Bioelectro healing - https://t.me/bioelectromagnetic_healing" | awk '{print $8}'
https://t.me/bioelectromagnetic_healing

The point I'm really trying to make is that that there may be more appropriate tools for a given task. For text processing tasks like this, it is well worth learning some AWK, regular expressions, sed and you already mentioned grep. Since those tools are made for the job, there's less to write yourself, which means less to test and debug and less to go wrong. The Grymoire has great tutorials on these things.

I'm a programmer at work and I often have to deal with text processing tasks like these - sometimes I'll have lists of items that need investigation or I have to do something to manually reprocess them in our systems and those kinds of tools help me focus on that instead of having to write a lot.
