printf / regex
Morning folks,

I need help with the following issue:

Let's say we I have the following output:
Code:
First Name:  Test
Last Name:   Test2
Number:   T1234
Number2:  T1234

Needed Output:
Code:
T1234


Now I want to grep/nawk/printf/sed out the Number:

- I like to search for T[0-9][0-9][0-9][0-9]
- Aditionally the script should just print out one T-Number (needed Output)


Can you help me to iplement this requirements into a one liner?

Cheers,

Domi

Code:
awk '/T[0-9]{4}/{print $2}' file | uniq

On Linux you have to add the '--posix' parameter for the regex to work correctly

Thank you guys.

@pludi

Your script does not work:

Code:
[user@host] ~
 # more file
iFirst Name:  Test
Last Name:   Test2
Number:   T1234
Number2:  T1234
[user@host] ~
 # awk '/T[0-9]{4}/{print $2}' file | uniq
[user@host] ~

@Christop Spoher
i can not use grep -o (I'm running Solaris 10 so I'm using -e instead)

Code:
[user@host] ~
 # /usr/xpg4/bin/grep -e "T[0-9]\{4\}" file | uniq
Number:   T1234
Number2:  T1234
[user@host] ~

@pludi, Christoph Spohr

What is when i have the following output:
Code:
First Name: Test
Last Name: Test2
Number: asd asdsf  234 T1234 ...dasda
Number 2: asd asdsf  234 T1234 ...dasda

So basically I'm looking for a solution without using "print $2"

Code:
Code:
sed -n '/T[0-9]\{4\}/{s/.*\(T[0-9]\{4\}\).*/\1/g;p}' file

Input:
Code:
First Name: Test
Last Name: Test2
Number: asd asdsf  234 T1234 ...dasda
Number 2: asd asdsf  234 T1234 ...dasda

Output:
Code:
T1234

If your sed doesn't support the ";"shortcut, you have to use a sedfile.

Hmm...

Code:
[user@host] /
 # more file
First Name: Test
Last Name: Test2
Number: asd asdsf  234 T1234 ...dasda
Number 2: asd asdsf  234 T1234 ...dasda
[user@host] /
 # sed -n '/T[0-9]\{4\}/{s/.*\(T[0-9]\{4\}\).*/\1/g;p}' file
sed: command garbled: /T[0-9]\{4\}/{s/.*\(T[0-9]\{4\}\).*/\1/g;p}
[user@host] /
 #

Do I really have to use a 'sedfile' in this case? Is there no other way?

Thx very much for your help.

Chris,

On Linux (Debian) it does work!

Code:
tester:~# more file
First Name: Test
Last Name: Test2
Number: asd asdsf  234T1234 ...dasda
Number 2: asd asdsf  234 T1234 ...dasda
tester:~# sed -n '/T[0-9]\{4\}/{s/.*\(T[0-9]\{4\}\).*/\1/g;p}' file | uniq
T1234
tester:~# uname -a
Linux tester 2.6.24-etchnhalf.1-486 #1 Tue Dec 2 07:03:38 UTC 2008 i686 GNU/Linux
tester:~#

Any idea what I can do on solaris?
