Creating an awk array from more than 1 field in multi field line

[icalderon]

hello all,

currently i am attempting to create an array in awk using a flat file as the source. the flat file format is as such:


word1 word2 word3

so i am attempting to use the NF awk parameter in order to assign values to the elements in the array. unfortunately this is not working just yet.

here is the code i currently have:

export x=0
delim=`awk '{print NF}' array_source.out`
export delim
echo $delim "is the value of the delimiter"

until (( x == delim ))

do
echo $x "is the pre math value for counter"

test[x]=`awk "BEGIN{ y = "$x" } NF == y { print $1 }" array_source.out`
x=`expr $x + 1`
echo $test[x]


echo $x "is the post math value for counter"
# echo $test[cnt1]
done

I am attempting to use NF to control which field is shoved into the array. By using a delimiter equal to NF in the source file that should control the loop as its delimiter.

However for some reason I cant get the array populated.

What am I missing here? I used this logic to create an array based on NR but this is new since it is a single line source file and I am using NF as a controller.

Any help would be GREAT! Tx!

Your script makes no sense.

It looks like you're not actually creating the array in awk, but just using awk to pull out the individual elements in the file to set up a shell array variable.

How about just using set -A test $(cat array_source.out)?

Tx Annihilannic! The set -A did the job just fine.

Much appreciated!
