Extracting specific block

Dastard · #1 (**permalink**) 02-25-2008

Hi Everyone , have a great day

i have a file which has almost 20,000 blocks each starting with this particular line " rTCCreditControlRecord " , how can i bring out the 7172 block out of that file

Thanks in Anticipation

Try both the following commands.

Quote:

grep '\rTCCreditControlRecord..*$' file
or
grep '^rTCCreditControlRecord..*$' file

Not working , meanwhile i have tried something like this

HTML Code:

while IFS= read -r EachLine
do
   'echo $EachLine
   if $EachLine = 'rTCCreditControlRecord'; then
   count = count + 1
   fi
   if count = 7172; then
   echo $EachLine
   fi
done < CCN02

where CCN02 is input file but its not working either

if count = 7172; then
>>>that is a string comparison

if count -eq 7172; then
>>>that is a numeric comparison

I think you would want the numeric comparison.

-r: is not an identifier

HTML Code:

#!/bin/sh
while IFS= read -r EachLine
do
   #echo $EachLine
   if $EachLine = 'rTCCreditControlRecord'; then
   count = count + 1
   fi
   if count -eq 7172; then 
   echo $EachLine
   fi
done < CCN02

Not Working

Add a display to echo to the screen what is happening. Could be count problem, $EachLine problem, file problem, etc...
By the way, wouldn't $EachLine be equal to the full line? rTCCreditControlRecord abcdefg 12345?

Code:

#!/bin/sh
while IFS= read -r EachLine
do
   #echo $EachLine
   if $EachLine = 'rTCCreditControlRecord'; then
   count = count + 1
   fi
   echo $count $EachLine   #for debug purposes
   if count -eq 7172; then 
   echo $EachLine
   fi
done < CCN02
