I already have accomplished this task using sed and arrays, but since I get the variable using awk, I figured I'd ask this question and maybe I can get a cleaner solution using strictly awk.. I just can't quite grasp it in awk.

I have a string of letters. (They happen to be DNA, not that it's relevant to the question.) For analysis purposes, I need to replace the information at some of the sites. I need to do this based on their position, not the information in that position.
I also need to ignore differences at other... (10 Replies)
Hi All,
When passing parameters to a sheel script, the parameters are referenced by their positions such as $1 for first parameter, $2 for second parameter. these positional values can only have values ranging from $0-$9 (0,1,2,3...9).
I have a shell script meant to accept 20 parameters. for... (3 Replies)
I have a variable that contains the number of a positional parameter. There is no way of knowing what number this may be, although it is guaranteed to correspond with a valid parameter.
In BASH I could just use ${@} to extract that argument. But in a Bourne shell the best I can come up with is... (3 Replies)

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
