I'm not sure that I understand? Can you show a sample of five or six different ticket numbers?

example the txt file have

D00000000
D00000001
D00000002
D00000003

Theses are the tickets numbers which is available in the txt file where i am in need to grep the ticket number only from the txt file

@laksh1999 Because you are attempting to use regular expressions with a tool that does not know WTF those are.
man grep is a wonderful thing.
If you are going to keep asking questions, you should learn to do a little basic reading.

but to spoon feed you...

# return lines with an A or D followed by 8 digits.
grep [AD][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]]

Sample:

stuff 1 A00000000 more stuff 1
stuff 2 B0000001 more stuff 2
stuff 3 C00000002 more stuff 3
stuff 4 D00000003 more stuff 4
stuff 5 E00000002 more stuff 5

Result:

cat test.txt | grep [AD][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]]
stuff 1 A00000000 more stuff 1
stuff 4 D00000003 more stuff 4

This does not work for me.I have tried this as well.I am not asking for spoon feeding for the same.

i have the json file with "id" ="D00000000" and "id"="V000000000" and i too have some id with encrypted data.i need to get only the D and V numbers and arranged in order from the json file which i have downloaded as .txt

json file

Then use json tools FFS.
man jq

cat wtf.txt | jq *.id

I would love to see proof because I just showed you proof it does work.

You didn't bother to read the man file.. i pulled that out of my ass from memory...

the correct syntax is jq '.id

but as this point I doubt you have the data you think you have in your text file.

JaredBusch

@jaredbusch said in Grep help:

the correct syntax is jq '.id'

I'm also assuming that id is one of the json keys based on your first post.

There are more id values are there in the txt file

Example)
This id value example is only for the 1 tickets
"id"="D00000000"
"id" ="V00000000"
"id"="eeeeeee-eeeeee-eeeee-eeeee"
"id"="eadsga-ereagag"

i just want to grep only D0000000 and V000000 values for each tickets.There are around 5000 tickets are there and each for more id for one ticket

want to grep

no you don't.

FFS how many times do I have to tell you.

Your data is json, use fucking jsontools.

jq is extremely powerful. Use it to correctly query your json data to get the result you need.
