Script Permissions
I have a script were I issue the following command:
Code:
perl -p -i -e "s/$v31a/$db2/" $dbn31

My script fails with permission error. However, at the command line I can edit the directory in question. I am using uname 002 in my script. So, why can i update manually but not in a script?

Depends what your script is actually doing. What are the values of those variables?

Also: The ability to edit a directory does not necessarily mean the ability to edit the files inside it.

You mean umask 002 ?

And you can try sed for the job: sed -i "s/$v31a/$db2/" $dbn31

Yes, the perl command is trying to update a file in place. From the command line, I can update the same file without permission error. So what is the difference?

The values are file names, and the current value and what the value should be changed to.

What file names? You may be hitting special characters which cause sed to barf or do funny things.
