Hello Jamie,

Following may help you. Let's say we have following input file.
Code:
cat test121
TEST1211
TEST
RTEST

Now example of ^.
Code:
awk '/^R/' test121
RTEST

Means it will show all text lines which are starting with letter R as above.

Example for ~.
Code:
awk '($0 ~ /TEST/)' test121
TEST1211
TEST
RTEST

Means if any line contains string TEST but it may contain any other additional values to which is match but not exact match as above.

For an exact match we can do following.
Code:
awk '($0 == "TEST")' test121
TEST

Thanks,
R. Singh

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
