Retrieve string from each line in a file based on a pattern in Unix
I have a file which contains several lines. Sample content of the file is as below.

Code:
OK    testmessage    email<test@123>
NOK    receivemessage    email<123@test>
NOK    receivemessage    email(123@test123)
NOK    receivemessage    email<abc@test>

i would like to know by scripting will it be possible to retrive just the mail addresses based on string provided, value is 'OK' or 'NOK'.

If i provide search string as 'NOK', i need the output as,

Code:
123@test
123@test123
abc@test

please note, email addresses are wrapped in either () or <> brackets.

Please let me know your comments.

p.s: i m new to scripting...

Code:
sed -n "/^NOK/s/.*[(<]\(.*\)[)>]/\1/p" infile
123@test
123@test123
abc@test

Or if your awk supports multi-character file-separators:
Code:
awk -F"[()<>]" '/^NOK/ { print $2 }' infile
123@test
123@test123
abc@test

With sed:

Code:
sed -n 's/^NOK.*[<(]\([^>)]*\)[)>].*/\1/p' infile
123@test
123@test123
abc@test

bash
Code:
read -p "Enter search string: " search
while read -r a b c
do
    case "$a" in
       "$search")
            c=${c/email/}
            echo ${c//[(<)>]/};;
    esac
done <"file"

output
Code:
$ ./shell.sh
Enter search string: NOK
123@test
123@test123
abc@test

Try:
for searching OK
Code:
sed -n '/ OK/ { s!.*OK:_[<(]\(.*@.*\)[>)]/Thanks/!\1!p; }' file

for searching NOK
Quote:
sed -n '/ NOK/ { s!.*OK:_[<(]\(.*@.*\)[>)]/Thanks/!\1!p; }' file
