I have a need for a way for a regular user (i.e. non root) to "override" a file on a filesystem with one of their own, but just for the lifetime of a script.
I'll give you an example.
One of my users runs a program which is distributed in a package (i.e. not changeable by them). That program is looking for a file, /path1/file1. My user would like to change this file to a different version of the file in different scripts.
I'm not aware of one, but is there a way to redirect file open calls for /path1/file1 to /path2/file2 in a script? It only has to be for file open/read calls, and not write. The /path1 filesystem is not writeable by the user.
How about something as simple as this: if [ -f /path2/file2 ] then FILEX=/path2/file2 else FILEX=/path1/file1 fi If /path2/file2 is too, errr variable, then perhaps an environment variable or a passed parameter? Cheers A.
