Extracting field from array

montana24 · #1 (**permalink**) 6 Days Ago

I have a problem with the following lines of code:

Code:

        SaveIFS=$IFS
        IFS="/"
        declare -a Array=($1)#take unix path, split by '/'
        website=${Array[4]} #stores website name

The confusing part is that it works on one machine, but not on the other.

If the code is moved to another machine, I get empty string instead of website (the path is identical on both machines).

Are you using the same shell on both machines?

It appeared to be different shell versions. The was a bug in the older one. Upgrading the shell fixed it. Thanks!
