[SOLVED] linux grep search

philip370 · 09-25-2019, 02:57 AM

So we have bee give a txt file jumbled we have been asked to find email address and IBAN references
I was able to figure out the grep search string for email addresses caine@caine:~/Downloads$ grep -E -o "\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}\b" dump1.txt
I am a bit lost for the IBAN search string. we need to search for (see attachment ) this structure within the junbled txt file..

What is the formula for the two-digit checksum?

grep will be too simple. You'll probably need a perl one-liner.

Yes I understand.. But we were specifucaly asked to use grep doesnt make sense to me either. I have adked the lecturer but his response was to use the IBAN structure and creat a search string using grep

you didn't figure out the email address one
you found that with an internet search

nice picture, but why not take a little time to type that out?

here are some sample, within some jumbled text
https://en.wikipedia.org/wiki/ISO_13616
ibansample.sh

Code:

#!/bin/bash
sampletext () {
        cat << EOF
Belgium     BE71096123456769
France  FR7630006000011234567890189
Germany     DE91100000000123456789
Greece  GR9608100010000001234567890

EOF
#TODO add junk
}

sampletext

Code:

./ibansample.sh | grep ...

Ok, you basically have the answer in #14 above, but which characters are allowed in the BBAN subcomponent and how many of them are there?

you didn't figure out the email address one

a lie

if you had figured out that pattern and not simply copy and pasted it, you would be able to do the IBAN pattern you are asking us to give you

philip370 · 09-25-2019, 06:04 AM

Fine fine fine u have the last word

Firerat · 09-25-2019, 06:04 AM

as soon as you start to show us some progress we will steer you in the right direction

thus far all you have done is ask us to give it to you

you didn't even give us the structure, or sample data
