Entering a TSO/E command from the z/OS shell

You can enter a TSO/E command from the shell in either of these ways:

Type the tso shell command before the TSO/E command. For example:
```
tso "oput source.c(hello) '/u/ehk/source/hello.c'"
```
The oput command is quoted so that the shell does not process it. If you are copying a file, specify the -t option to copy a file to your current directory. For more information about the tso command and its options, see z/OS UNIX System Services Command Reference.
Type the command on the shell command line and press the TSO function key.
When the TSO/E command completes, typically *** is displayed on the screen. To return to the shell and resume working at the shell command line, press <Enter> or <Clear>.

Use the man command to view descriptions of TSO/E commands by prefixing the command with tso. For example, to view a description of the MOUNT command, you would enter:

man tsomount

For complete information about the man command, see the man command description in z/OS UNIX System Services Command Reference.

Command not found? If you type a TSO/E command from the shell and press <Enter> instead of the TSO function key, you may receive a message that the command is not found. Because you did not press the TSO function key, the shell attempted to process the command as a shell command. (You can use the Retrieve function key to redisplay the command.)
