Error awk or grep ??
Hi All,

I need to creat one cutdown file from one full file. The full file may looks as below:

UHL1 08007 DDLIST 000
O301107121212A & L TRANSFER IN ALCB ...................
A301107121212720000IBACS LIAISON ...................

A120607232323720000IBACS LIAISON ...................
O130707241010AULD PROPERTIES LTD RAYMOND AULD .......
UTL1064600

I need to extract only lines which starts from "O" to my cutdown file from full file.
Also from this selected lines (which has "O") I need only few position fields.
Position for these fields from full file are (from 8-13),(from 14-30) and (from 36-40).
And each cutdown file record should start with "DTL1".

Finally my cutdown file should look like below:
DTL121212A & L TRANSFER IN ALCB........
DTL1138202B O C THE DIRECT DEBIT DEPT......
.
. etc.,

I know how to select the lines with "O" using grep. But I dont know how to insert DTL1 to each line and also how to select position for this.

I know this can be implemented in awk easily, but Iam not much exposure to awk.

Pls help me achieve this...

Hi,

Am also very new to awk.
But the below command can work out a part of ur query
awk '/^O/ { print "DTL1" $1 }' <filename>
The above command gives the o/p as below:
DTL1O301107121212A
DTL1O060807138202B
DTL1O301106202001ZEUS
DTL1O060807214209COMMERCIAL
DTL1O120607232323A
DTL1O130707241010AULD

As ur file doesnot have any coloumn separator Am not aware of how to print the positional paramaeters.

if there is a space inbetween two strings in a file , then awk consider it as two different arguments.Hence "O301107121212A" is the first argument and "&" "L" "TRANSFER" "IN" "ALCB" are the 2nd 3rd etc arguments.

Regards,
Jisha

There is something wrong with your specification for the fields you want outputted.
Your sample output is variable length but you specify fixed field lengths.

grep "^O" file | cut -c 8-13,14-30,36-40 | while read line ; do echo DTL1$line ;done

o/p as per your data:
DTL1121212A & L TRANSFER IN ....

And here is the same solution using sed

Code:
sed -n -e 's/\(^O.\{6\}\)\(.\{23\}\)\(.\{5\}\)\(.\{5\}\)\(.*$\)/DTLI\2\4/p' file

Code:
sed -n -e "s/^O.\{6\}\(.\{23\}\).\{5\}\(.\{5\}\).*/DTL1\1\2/p" input.txt
