Can I use AWK to read a file line by line and feed to a program?

[QAGuy]

I need to read a file line by line and feed the input into a program. All of this is happening within a shell script. The file has two fields, and I need to assign the values to variables which will then be passed to another program. I'm using "for file in file_name do" to go through the file. Thanks [sig][/sig]

Hi, haven't tried this and my memory may let me down ... but can't you do something like this below. I'll assume the fields are separated by space, but you can specify anything in the -d switch in cut.

[tt]
for fline in `cat myfilename`
do
VAR1=`cut -d" " -f1 $fline`
VAR2=`cut -d" " -f2 $fline`
#run your program
done
[/tt]

It's Unix, so no doubt there are a hundred other ways too!

This also works when you have more then one field per line.

while read x
do
set $x
echo $# ## How many fields
echo $3 ## Print the third field
done < inputfile
