parse csv file, sha1 hash and output
I have a file, not really a csv, but containing delineated data just the same. Lets call that file "raw_data.txt". It contains data in the format of company name:fein number like this:

Code:
first company name:123456789
second company name:987654321

what i need to do is read this file, apply sha1 to the fein field and then output that into a new file, we'll call "hashed_data.txt". So hashed_data.txt should contain data like

Code:
first company name:f7c3bc1d808e04732adf679965ccc34ca7ae3441
second company name:bfe54caa6d483cc3887dce9d1b8eb91408f1ea7a

i have tried looping thru the file with awk like so

Code:
read FILE
while read line
do
        awk 'BEGIN{FS=OFS=":"}{print $1, $2}'
done < $FILE

but I'm stuck on how to run the second field thru sha1sum
