OSHELL
Description
OSHELL uses BPXBATCH to run the shell command or shell script:
oshell shell_command
For example, to display process information, enter:
oshell ps –ej
When you use OSHELL, do not use an & to run a shell command in the
background. For more information about BPXBATCH, see Appendix D, “Running
shell scripts or executable files under MVS environments,” on page 891
Some examples of using the OSHELL command are:
v List files in a directory
v Create, delete, or rename directories, files, and special files
v Display contents of a file
v Copy files
v Display file attributes
v Search files for text strings
v Compare files or directories
v Run executable files
v Display the attributes and contents of a symbolic link (symlink)
v Set up character special files
v Set up standard directories for a root file system
Some of these tasks may require superuser authority.
OSTEPLIB — Build a list of files
Format
Description
OSTEPLIB pathname
Use the OSTEPLIB command to build a list of files that are sanctioned by your
installation as valid step libraries for programs that have the set-user-ID or
set-group-ID bit set. This permission setting allows a program to have temporary
access to files that are not normally accessible to other users. Step libraries have
many uses; for example, selected users can test new versions of runtime libraries
before the new versions are made generally available.
You must have superuser authority to issue OSTEPLIB.
The sanctioned list is valid if it conforms to the following rules:
v You can include comment lines in the list. Each comment line must start with /*
and end with */.
v You must follow standard MVS data set naming conventions in naming the files
in the list.
v Each data set name must be fully qualified and cannot be enclosed in quotation
marks.
v Each data set name must be on a line by itself, with no comments.
v You can put blanks before and after each data set name. Entirely blank lines in
the list are ignored.
