Re: help with the script.

First, read this to understand why you're have difficulty with angle brackets. And a hint to everyone, I clicked on "quote" for his original post to see his original input. That way I could that his here-document was correct.

rooh, I would have sworn that I knew everything about ksh. But I have never seen your "for" statement syntax before. I tested it and it works. I looked in The New Kornshell Command and Programming Language by Morris Bolsky and David Korn. It's not there. They only show
for i in $list
do
done
and they never mention
for i in $list
{
}
Where did you get this syntax??

You really posted a fragment of a script so it's hard to do anything but visually inspect. But here is something that looks like a double loop waiting to happen:

for record in `cat $bpfile`

{
acode1=`awk '{print $2 }' $bpfile`
ename=`awk ' {print $1 }' $bpfile`
dept1=`awk '{ print $6 }' $bpfile|cut -c 1 `

I think that you either want to lose that "for" loop or crack "record" up into acode1, ename, and dept1.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
