No, awk checks the expression against every line in the file, sort of like how grep does. But awk has comparisons and variables and all the things you need to actually write a program, where grep can only match and print lines.

I have another question about it, that is ,when I get the number(416), how can I print out the number in the 3rd column of this row(928)?
I want to grep from a file an exact character match.
I tried grep -c "$a $b" $file
where a=6 and b=2
the problem is that I get: 6 2 and 6 20
I just need a count of the occurrence.
I'm using the Bourne shell.
I've also tried grep -c '$a $b' $file;
not sure how to do this - any suggestions? (3 Replies)

igawk
IGAWK(1) Utility Commands IGAWK(1)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
