How to use awk for a variable in UNIX script

Question

I would like to use awk for a variable
that has the form abc,def

I also don't know how to use awk for a variable instead of a file
I tried the following but it doesn't works

awk -F, '{$1" "$2}' $var
and
awk -F, '{$1" "$2}' "$var"

What do you want to do with the variable? awk may not be the best tool for the job. — chepner

Use a herestring

awk 'commands' <<< "$string"

Also if you want to print the first two fields of a comma separated string, change the command to

awk -F, '{print $1, $2}' <<< "$string"

You can do something like this:

echo "$variable" | awk -F, '{print $1 " " $2}'
