thanks to all who helped, i recieved over 20 responses in 10 minutes.
Several people mentioned the list is not for this type of question, sorry
about that.
if anyone knows a good shell script list id like to know.

the solution was to to use the IFS variable, which i think tells cat to use
that value as its field seperator, just make to sure to set IFS back to its
original value when done or you can break alot of other stuff.

thanks again!

Well, in the simplest case, you simply need to alter 'IFS'
(Inter-field separator)
It defaults to 'whitespace'.

And I'd recommend 'saving' it because otherwise stuff can break

<your script>

You may also wish to consider doing something like (after setting the IFS):
for i in `cat file`
  set $i


(Although if you're doing that kind if thing, I might suggest having a look
at perl)


Subject:    shell script help

i need help parsing a text file in korn shell on solaris 7. I cant use
i want to grab each line of an input file then break out the columns
(probably using awk).

here is a sample input file:

TEXT,04/04/04,04/20/04,05/01/03,a description with spaces in it.
JUNK, 4324, 4323432, 324231, another description with spaces in it.

i was using the following code, but then the users started putting spaces
in the last column and broke my script:

for i in `cat inputfile`
KEY=`echo $i|awk -F, '{print $1}'`
EDATE=`echo $i|awk -F, '{print $2}'`
MR=`echo $i|awk -F, '{print $3}'`
ENDDATE=`echo $i|awk -F, '{print $4}'`
LASTCOL=`echo $i | awk '{print $5}'`

thanx in advance!
