Top Forums UNIX for Beginners Questions & Answers Reading value from a file Post 303034332 by vgersh99 on Tuesday 23rd of April 2019 11:43:37 AM

not sure if your file is : separated or not - your sample file from post#1 seems to indicate that it's space separated, but..

Code:
#while IFS=: read server db user prof junk
while read server db user prof junk
do
  if [ "${server}" = 'server1' ]; then
     echo "server:[${server}] db:[${db}] user:[${user}] prof:[{${prof}]"
  fi
done < myInputFile

If the input file is : separated, uncomment the first #while comment-ed line and comment out the 2nd.
