Hey Jim,

Thanks, that is really close; I'm getting the output below. How can I print a new line instead of the second grep output (i.e. 'MOVE LIT2 TO VAR2') and a new line?

Code:

LIT1LIT2MOVE LIT2  TO VAR2
LIT3LIT4MOVE LIT4  TO VAR2
LIT5LIT6MOVE LIT6  TO VAR2

Hey chebarbudo,

My grep doesn't like the -r option; I get 'sed: illegal option -- r'.

Jim,

Also, I forgot to answer..

There are always 2 move statements with the same variable names as a coding convention our programmers use.

Right, there will not always be a period at the end of the statement.

Thanks Jim, I got it to work by using this:

Code:

egrep '(VAR1$|VAR1\.$|VAR2$|VAR2\.$)'  $program | 
       awk '{ printf("%s", $2);  if(FNR%2==0) {printf("\n")}}'  | tr -d \'
 
LIT1LIT2
LIT3LIT4
LIT5LIT6

Thanks again!

-Jay

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
