Top Forums Shell Programming and Scripting Access line by line from a file with shell script Post 302824681 by rbatte1 on Friday 21st of June 2013 10:00:02 AM

Please use the code tags to wrap around your output.

Consider the loop:-
Code:
#!/bin/ksh
while read dir
do
   echo "Working on directory $dir"
   some processing here
done < input_file

Does that structure help? For each line in the input file, it will print out the message and anything else you care to insert.



I hope that this helps.
