We still run COBOL on unix. Mostly we use PL/SQL.
But the real question is “How many languages do you know?”
I routinely write Unix shell scripts, SAS, SQR, PL/SQL, COBOL, C, VBScript, Office VB and Javascript. Java programmers are the most highly sought but Java has become a security nightmare.
Once you have a few good languages under your belt, picking up another is fairly simple.
I have the same list, minus Java but adding PowerShell scripting. Used to write Speed code. Have dabbled in PL/N and IBM assembler.

The security problems are so minor in comparison to how Java is generally used (on the server). The problem is with Oracle’s runtime plug-in for web browser so that Java applets can run. How many applets do you run? I’m guessing zero.
Remove the java plug-in for your web browser and you’ll be fine.
