Using OSHELL to run shell commands and scripts from MVS™
You can use the OSHELL REXX exec to run a shell command or shell script
from the TSO/E READY prompt and display the output
to your terminal. This exec uses BPXBATCH to run the shell command
or shell script:
oshell shell_command
For example, to display process information, enter:
oshell ps –ej
Restriction: With this exec, do not use an & to run a shell command in the background.
