How do I find the version of Informatica, Cognos and DataStage on SUNOS 5.8

How do I find the version of Informatica, Cognos and DataStage using a unix command on my Unix machine SunOS 5.8.

I don't want to use front end to find this information.

pkginfo -l if these were loaded as packages.

If not, there may be a -v or -V switch that allows finding version.
Or, strings command sometimes can work - see the man page - send output to grep for (-i) version.
