Top Forums UNIX for Dummies Questions & Answers How to take input from two files in a UNIX script? Post 302780411 by Corona688 on Thursday 14th of March 2013 01:13:40 PM

Same file with delimiters:

Code:
while IFS="," read VAR1 VAR2 THEREST
do
        ...
done < inputfile

Two files:

Code:
exec 5<file1 # Open file into FD 5
exec 6<file2

while read VAR1 <&5 && read VAR2 <&6
do
        ...
done

exec 5<&- # Close FD 5
exec 6<&-

One file would obviously be preferable.

Also, you don't need to reopen Results.txt 9,000 times to write 9,000 lines to it. You can redirect the output of your loop the same way you redirect its input.

Code:
while ...
do
...
done > results.txt
