If you have installed the product to a directory other than the default one, you need to set the environment as described below.
. <product-install-dir>/bin/cobsetenv
cob -V
To avoid having to run cobsetenv for every shell, add these commands to the shell initialization files (such as /etc/profile, /etc/bashrc).
Note that cobsetenv is only compatible with POSIX-like shells, such as bash, ksh, or XPG4 sh. It is not compatible with C-shell or pre-XPG4 Bourne shell.
