Shell Programming and Scripting

Using KSH, I have one text file which just contains a list of distinct references on each line, e.g.;

123456789
987654321
15457544X
164450200

etc. The file will always be called "InputRefs.txt".

The number of distinct refs will be different each time.

For each line (distinct ref) I want to create a new text file. The file name should be the same as the reference, followed by .txt. and the contents of the text file should be a standard message which is the same in each file, e.g. "This is a standard message, same in each file. Thank you".

Additionally, I need to create a new 'control file' which is basically a CSV text file with a record for each of the records in the first file, with some additional standardised fields.

E.g. in the above example, the control file's first row would be;

"123456789.doc","123456789","DOCTYPE",20/01/2012 00:00:00,"B"

Fields 1 and 2 refer to the ref in the first file. Fields 3 - 5 are the same for each other row in the file, but the date must be the run date.

The name of the control file should be "ControlFile_20120120_17_01_20).csv" (with the date being the run date, and the last values the time - 17:01:20).

Can anyone assist?

I thought about using a grep in a for loop, but how would I print the standard message in each .txc file? Also really unsure about getting the date in the control contents and the date+time onto the control file's name.

Thank you.

In ksh I would use a read loop:

Code:

while read reference
do
  echo "your operations with variable $reference go here"
done < InputRefs.txt
