Filtering data using uniq and sed
Hello,

Does anyone know an easy way to filter this type of file? I want to get everything that has score (column 2) 100.00 and get rid of duplicates (for example gi|332198263|gb|EGK18963.1| below), so I guess uniq can be used for this?

Code:
gi|3379182634|gb|EGK18561.1|	100.00
gi|332198263|gb|EGK18963.1|	100.00
gi|332936633|ref|EGK16471.1|	97.00
gi|3329991602|ref|EGK11733.1|	100.00
gi|332198263|gb|EGK18963.1|	100.00
gi|332302583|gb|EGK13714.1|	98.00

I want to choose these ones.
Code:
gi|3379182634|gb|EGK18561.1|	100.00
gi|332198263|gb|EGK18963.1|	100.00
gi|3329991602|ref|EGK11733.1|	100.00

In the end, I want the output to look like this.. Is it possible to use sed for this?
OUTPUT:
Code:
EGK18561.1
EGK18963.1
EGK11733.1

Can anyone please help? Thanks so much in advance!

You may try awk solution its easy, Others might have sed solution

Code:
$ awk -F'[|]' '$5==100 && !A[$4]++ {print $4}' file

OR
Code:
$ grep -E '(100)'  file | cut -d '|' -f4 | sort | uniq

Resulting
Code:
EGK18561.1
EGK18963.1
EGK11733.1

Hello Akshay,
Thanks for your response. It didn't seem to work and gave me this error message: "A[: Event not found." Smilie

That is because of history expansion in bash, which interprets the exclamation mark, even within double quotes. You need to use single quotes like Akshay showed, not double quotes.
You can turn off history expansion altogether with
Code:
set +H

What constitutes a duplicate? $4 (the 4th field), the entire line? Does $2 have a 1:1 correlation with $4? If it is the entire line for example you could use !A[$0]++ instead of !A[$4]++ in Akshay's suggestion..

awk '$2==100' a | sort | uniq
