Syntax issue with awk statement

line=catsanddogs;awk -v var="$line" RS= '$3=="`var`"' master_file.sql > jaylog
awk: cmd. line:1: RS=
awk: cmd. line:1:    ^ unexpected newline or end of string

I'm trying to incorporate a variable into this statement but I can't get the syntax to work correctly.

The following, of course, works fine:

awk -v RS= '$3=="`catsanddogs`"' master_file.sql > jaylog

There are two problems.

First, since you didn't use the -v option before the variable assignment, awk thinks the argument RS= is the script, and that's not a valid awk script.

Second, awk doesn't expand variables inside quoted strings, they're treated literally. You need to concatenate the var variable to the backtick strings, not put it inside the string.

awk -v var="$line" -v RS= '$3=="`" var "`"' master_file.sql > jaylog
