[SOLVED] Shell script urgent help please

shellquery26666 · 11-14-2017, 07:08 PM

Hello,

I have below string, even I have hundered of lines in a file. I want to exactly match last two consecutive strings.

2017-09-30|ACBD,TVF|01234|NULL|18|NULL|686091802|BANK OF ABCD, LIMITED, THE|2017-09-30 00:00:00

I want to extract the string "2017-09-30 00:00:00"

How can I do this please?

As date 2017-09-30 appears two times so I only want to search lines in a file which has string "2017-09-30 00:00:00"

Need urgent help please

Did I miss something?

Code:

grep "2017-09-30 00:00:00" filename.txt

If the need for help is so urgent, next time show us what you attempted and why it didn't work for you. That way we can maybe help you better.

Welcome to LQ!

Please see the Site FAQ for guidance in asking questions, and what supporting information to provide. It is always good practice to show what you have already tried and what the results were as well.

The title of your post should include the topic of your question to attract the most appropriate help from members. And please remember that everyone here volunteers their time and expertise, so asking for urgent help is not appropriate and may be considered rude by others.

The advice already given to use grep, or other regular expression search tool is the way to go. You can begin with grep, which is the basic Linux file search tool, see man grep for details. You may also find sed, awk and man regex helpful.

Give those a try and let us know how you progress. Good luck!

Or maybe

Code:

grep "2017-09-30 00:00:00$" filename.txt

or, if the time part is not fixed:

Code:

grep "2017-09-30.*$" filename.txt

That said, yes

Code:

man grep

and understand that the code we've shown you is going to return the whole line that matches, not just the pattern matched.

OP seems to never have logged-in since posting

@shellquery26666:
The 'soft skill' of www-search is much faster and thus better
than posting 'basic' questions. Try a search like:
linux beginner tutorial man string match

Also try web-searching: "soft skills" for IT|ICT

Let us know IF you are serious about participating here at LQ.
Tell us a little about: your PC, distro, Linux experience/interest/goal.

Best wishes shellquery26666.
