Shell Programming and Scripting

now would you be kind enough try to explain what it really did.

nawk '{$1="";$0=substr($0,2)}1' file > outfile

Dear All

I have a pattern which look like this:

2 20080224_04:11:14.021 ISC-Libya BritishTelecom1 68 IAM 249129406720 218926283155 b 3943 ACM f 11117 REL b 11224 RLC :COMMA: NCI=10,FCI=6101,CPC=0A,TMR=00,OFI=80,USI: :COMMB: BCI=1234: :RELCAUSE:10:


2 20080224_04:10:03.578 ISC-Libya BritishTelecom2 38 IAM 20186946784 218927207018 b 646 ACM b 3060 CPG b 21348 ANM f 81542 REL b 81712 RLC :COMMA: NCI=10,FCI=6101,CPC=0A,TMR=00,OFI=80,USI: :COMMB: BCI=0234: :RELCAUSE:1F:

I have alot of these samples and they are placed in files which is created every 15 minutes of name (CDR.Date1) and then after 15 minutes (CDR.date2) and so on

Note that the arrangement of the fields is not fixed at all but i need every time to print a certain fields.

I want the output to be :

ISC-Libya British-Telecom2 b f b
ISC-Libya British-Telecom2 b b b f b

as you see the character b and character f repeated in the same pattern so i want a script as soon as it find any b or any f or any ISC-Libya or British Telecom to print it with the same order it comes with inside the pattern.

Please Reply thanks in advance

in my last question please i would like output to be like this

ISC-Libya British-Telecom2 b f b 10
ISC-Libya British-Telecom2 b b b f b 1F

No change in the message conepts just output format

Thanks in advance

Don't hijack a thread but start a new one.

@knijjar

An explaination of the command:

Code:

nawk '{$1="";$0=substr($0,2)}1' file > outfile

$1="" -> empty the first field
$0=substr($0,2) -> start the whole line at the second position and ignore the space at the first position
1 -> awk evaluates this as true and the default action is to print the line

Hope this helps.
