question about awk
Hi,

I have this,

awk '{for(x=1;x<=NF;x++) {array[x] = $x}}' input.txt

where input.txt has only one line (comma deliminated) and I am trying to get the data into an array. For some reason, the array is empty. Can someone please tell me what is wrong with this statement?

Thanks.

@viko: You need to pass the shell variable to awk
Code:
$ str="a b c"
$ echo $str
a b c
$ awk -v string="$str" 'BEGIN { split(string,a); for(i in a) print "=> " a[i]; }'
=> b
=> c
=> a

@ycshen: You need to pass comma as the field separator.
Code:
awk -F, {...}

thanks agn, that was helpful for me, but i don't know how to use the array back in shell


i know
a=`awk -v string="$str" 'BEGIN { split(string,a); for(i in a) print "=> " a[i]; }'`

but obviously that doesn't bring me the entire array

can someone help me a little more?
