How do you append info to an environment variable?

  • 772

The method export vname=value will override the original value. I want a way to append to the old value by colon.

Any idea how? Thanks.

    Try this:

    export vname=${vname}:appendedtext

    Demo:

    $ export foo=bar
$ echo $foo
bar
$ export foo=${foo}:baz
$ echo $foo
bar:baz
