How can I read ach line in a file into two variables: one for the last field, and the the other for the other fields ?
For example, I have a file:
hello world! 10s It is a good day. 4m ...
I would like to read each line into two variables: one variable contains the time interval at the end of the line, and the other variable contains the fields before it. I was wondering how to do it?
while read line do ... # split $line into $message and $interval echo "$message" sleep "$interval" done < "$inputfile"
