Reading line by line from file. - UNIX for Dummies Questions & Answers

Hi,

I am trying to do the following in a ksh script:

Loop until (eof)

in_line = current input line from file

Statements.

end loop.

But have been having trouble finding syntax and such for scripting in this language. Could some one point me in the right direction? I would especially like to know about good, free, online reference material.

Thanks,

Amber Taylor

I would use something like this:

Code:

#! /usr/bin/ksh
exec < inputfile

while read in_line ; do
     echo line = $in_line
done

Thank you for your help. Do you know where to find any kind of online reference for working on ksh files?

Thanks,

you could also use a for loop.

Code:

for i in `cat filename`;do
processing.....
done

$i will = each line in the file.

Books: oreilly.com has a book called "Learning the Korn Shell" another great book.
