This part describes the Time Sharing Option Extensions (TSO/E) OMVS command that you use to invoke the shell and the TSO/E commands that you can use to work with the z/OS UNIX file system.
The OMVS command invokes the z/OS shell. You can enter the OMVS command from TSO/E or from the ISPF command processor panel.
- The Interactive System Productivity Facility (ISPF)
command processor panel (typically, option 6 on the ISPF menu).
Option 6 is usually preferable, because it does not convert into uppercase the commands that you enter. You should enter a TSO/E command from an ISPF panel that does not convert all the parameters into uppercase; some panels, such as the main ISPF panel, convert what you enter into uppercase. z/OS UNIX System Services is case-sensitive.
- The shell
- The relative path name is relative to the working directory (usually the HOME directory) of the TSO/E session, not the shell session.
- Use absolute path names when entering any TSO/E commands.
- Avoid using spaces or single quotation marks within path names.
