Shell Programming and Scripting

Reading this file. I want to read all 4 fields.

If 2 is populated with a p, I want to set $TYPEP to "Printers",
if not should be empty.
If 3 is populated with an r, I want to set $TYPER to "REQ Printers"
if not should be empty.
If 4 is populated with letter o, I want to set $TYPEO to "Orders"
if not should be empty.

The problem I am having is that it looks like case only lets me fall through it once. I canot get $TYPEP $TYPER $TYPEO to reset to empty after reading each record.

Here is snippet of my file, code and output.

Here is snippet of my file:
=======
100:::o:
51:p:r::
52:p:r::
53:p:r::

note: my preview of snippet of the file is showing smiles. Maybe we can start a new thing, smile separated values? :cool: (Just kidding!) Not sure how to get rid of that but it is just 4 colon separated fields, 4 records
I replace colons with commas so you can read it correctly:

100,,,o,
51,p,r,,
52,p,r,,
53,p,r,,

using ksh on AIX 5.3 ML04
You see thar "Orders" prints for each of the 4 lines. It should have only printed for the first. The other 3 should have printed both "Printers" and REQ Printers"
Any suggestion is appreciated. I think I am using the wrong tool. If you can point me to a more suitable function or command or tool, I appreciate it.

Code:

case ${pflag} in 
p)
       TYPEP="Printers"
       ;;
*)
       TYPEP=""
       ;;
esac
case ${rflag} in 
r)
       TYPER="REQ Printers"
       ;;
*)
       TYPER=""
       ;;
esac
case ${oflag} in 
o)
       TYPEO="Orders"
       ;;
*)
       TYPEO=""
       ;;
esac

See your file is and logic is clear, but what output you want from this is not clear, can you write down you output only..

Check the box below the text area that says "Disable smilies in text".

The typeset command is not standard. It is better to set the printing widths in your printf format string.

Shouldn't you set IFS to your delimiter?

Code:

while IFS=: read -r no pflag rflag oflag

You should reset your flags before processing each line.

Code:

while ..... read ....
do
  unset pflag rflag oflag
  ...

Or:

Code:

while ..... read ....
do
   pflag= rflag= oflag=
   ...

I replaced my case section with this one and now TYPEO is populated on first row but not the rest. TYPEP and TYPER showing empty on all rows!
Not sure why. Maybe I should post entire script, but I put *alot* of documentation in there. I have high hopes for the script and doc and script are not complete and out of synch! Sometimes (alot of times!)results are what you least expect!

To debug it try:

Code:

echo oflag = $oflag
case ${oflag} in 
o)
       TYPEO="Orders"
       ;;
*)
       TYPEO=""
       ;;
esac
echo TYPEO = $TYPEO

You will find that oflag was not set to "o" if TYPEO is getting set to "".

That is the kind of behaviour of case is is perplexing me. I don't want to be assuming but I am attaching input, output and the entrire script. You will see in the input file towards the middle and end, oflag is set to o and the TYPO is still not populating. I wonder if TYPO isn't a reserved variable?
