Shell Script that misbehaves under Linux but works in HP UX well... ksh environ.

Hello,

I have this long shell script that I have ported to Linux from HPUX. It is running fine on HPUX. I am running it under ksh in both the places.
On Linux it gives me an error message that doesn't give me any clue to what is happening. The error message is this.
SquDex: binLinux/Milling[128]: 0.00: unexpected `.'
SquDex: binLinux/Milling[128]: 0.00: unexpected `.'
SquDex is the main program that I started and binLinux/Milling is the other program it calls in between. I have no idea what this means: 0.00: unexpected `.'
I tried to run set -vx, but that doesn't give me any clue. Is there a way to run shell scripts line by line and debug?
Or does anybody have any clue what such an error means?
THe program runs and gives me the out put but since this error message is coming, I cant run the program in the production env. Please let me know if anybody has any suggestions...
Regards
Thanks in anticipation...

It means one of your lines is formatted wrong.

It could be missing a (") or a (.) or many other "grammatical" mistakes.

Or you had a typo and added an extra mark that is out of place.

The: (unexpected `.') makes me think you have a (.) somewhere when you shouldn't.

Check line 128.

That looks like a error message from the program rather than from ksh.

I believe (that works for sh) add a -v to the first line which probably reads
# /bin/ksh
so it reads
#! /bin/ksh -v

That will show all commands that are getting executed. (I'm not 100% sure with ksh, always program in sh).

Or you could find the line where this SquDex is executed, and modify it so it says

echo " <the original line> "
and put
exit

behind it, so you will see how and with which parameters that program would have been called. Then try executing the same thing on the command line and see what you get.

Hope it helps,

mlp,
Thanks. I think I saw the line where it is doing. It is taking a variable Bro and it is reading the value of that into another variable vBro. Bro should be integar, but somehow it came in as 0.00. How I can tell it to take only the integar value of it, like 0 only and not 0.00. Sorry for this silly question, but I am not a programmer.
Thanks

If it's predictable that it's alway in the form x.y. and you always want x, you could do

Code:

vBro=` echo $vBro | awk -F. '{print $1}'`

(note the backquotes ``)

The awk splits the fields, using the dot as separator and gives you the first field (the first "0" in your case). But it might be easier to find out why the form is what it is.

Hope it helps,

Thanks. I am a little bit afraid to open this program and make this sort of changes. If I send the two programs that uses this, will you be able to look at it?
Thanks

Well, yes, but what does it do? Why don't you post the script if it's not too big and I can have a look.

mlp,
Thanks. IT comes to around 30 k as 4 files that are related. I guess we can't have attachments here in this forum. How can I send it. I think it will be too big for this place. I can e-mail it to you as an attachment. I can explain which program calls which also. Please let me know.
By the way, I tried your suggestion and it worked for one variable. I will have to do that for other three variables too looks like.... Thanks very much. But it bugs me why that error is coming at all. ...
Thanks
Bye
