Hey Don,
I had to fix my shebang to #!/usr/bin/ksh, but it did not help. I have to run on ksh88 as i have no other choice and the output from your request is as follows with ksh88: The ksh88 does not like the parenthesis. ksh93 has no problem with the parenthesis, but that is not the version which i need it to run. Thanks again.
The following code in ksh88:
produces the output:

Don - I have a working solution, thanks to your efforts. This will allow me to take vendor code upgrades and spit out which of the property files have changes in numerous directories. This will save a ton of time, as currently we are going through each of them manually. I can't tell you now much i appreciate this. Here is the final solution. Thanks again.
How about defining a function like
that you call with a path, a number (two or more) of subdirectories, and two versions to compare, both latter separated by spaces?
The post#12 does not work with an old Bourne shell
Maybe a bug? The shell seems to remember the file name, not the handle.
This modification makes it work:
The previous post can easily feed a while loop
The post#12 does not work with an old Bourne shell
[..]
The Bourne shell is not a POSIX compliant shell, so the code was not intended to work with it. The $(....) construct does not exist in the Bourne shell, however this could easily be replace with backticks.
Using backticks, I got the same error with a Bourne shell.
This part does not seem to work:
But I do not see a reason why it should not work.
Anyway, there is rarely a reason to script with the Bourne shell nowadays, since even now ancient Unix systems have at least one Posix compliant shell available.

Just have it drop what it is doing when it reaches this command and start again at the same number it was at? I know I could make a while loop and just... (0 Replies)
