MVSCMD(1)
NAME
mvscmd - Run an unauthorized MVS command (program) that resides in a PDS or PDSE from the UNIX System Services command line. To run an authorized MVS command (program), use mvscmdauth.
SYNOPSIS
mvscmd [OPTION]*
Where OPTION is one or more of:
-a=<args>, --args=<args>
The program arguments, such as -a='MARGINS(1,72)'. Default is ''.
-b, --buildinfo
Display build information of this program.
-d, --debug
Display even more verbose messages and retain temporary datasets.
--<ddname>=<value>,[<options>]*
Specify a DDName to associate with a dataset, UNIX file, or volume.
Typically, no options are required. Options are ignored for STEPLIB
DDNames.
See DDNAME OPTIONS section for more information.
-h, --help, --info
Display this help message.
-j, --json
Print output in JSON format. The output has the following structure:
{
"data": {
"STEPLIB": "none",
"program": "IEBCOPY",
"DDs": [
{
"ddname": "SYSOUT",
"type": "console",
"name": "IBMUSER.P0000001.T0000001",
"retained": false,
"content": "sample text\n",
"content_length": 12
}
]
},
"program": "mvscmd",
"rc": "0",
"options": "-j --pgm=iefbr14 --sysout=*"
}
-J, --prettyjson
Print JSON output in a readable format, with line breaks and indentation.
-p=<name>, --pgm=<name>
Specify the program to run, e.g. -p=iebcopy
--steplib=<dataset>
Specify dataset to search for program. For example: --steplib=MY.DATASET.
By default, mvscmd searches the STEPLIB linklist for the specified
program.
--tmphlq=<tmphlq> | -Q=<tmphlq>
Override the default high-level qualifier (HLQ) used for temporary dataset
names, which also overrides the TMPHLQ environment variable if set.
The default HLQ is based on the login name of the current user.
-v, --verbose
Display verbose messages.
DDNAME OPTIONS
The following options can be used with the `--ddname` argument.
For datasets:
excl

allocated this dataset already then the allocation will
fail. If the allocation succeeds, no other job can
allocate this dataset until this program completes.
mod
Allocate dataset or file for update (modification).
old
Synonym for 'excl'
vio
Allocate the dataset as a virtual I/O DD name, if possible.
vol
Allocate the DD name to a volume. Unlike dataset allocation,
the value specified is the volume name.

for mvscmd, mvscmdauth, and dtouch.
Suboptions for the 'new' operator are as follows:

keylen
Length, in bytes, for each record's key in
Key Sequenced Datasets (KSDS).
keyoffset
Bytes from the beginning of each record where the key is located.

SMS-rule. Not valid for datasets that are not
SMS-managed. Note that all non-linear VSAM datasets are
SMS-managed.
normdisp
Tells the system what to do with the dataset after normal
termination of the program.
May be one of delete, keep, catalog, uncatalog.
Defaults to 'catalog'.
primary
Is the amount of primary space to allocate for the dataset.
Default is 5M.
Size may include a suffix of K or KB (kilobytes),
M or MB (megabytes), G or GB (gigabytes),
C or CYL (cylinders), T or TRK (tracks).
recfm
The record format for the dataset.
One of FB, VB, FBA, VBA, U. Default is 'FB'.

PDS, PDSE/LIBRARY, HFS.
Default is 'PDSE'.
For types with multiple names (SEQ/BASIC, PDSE/LIBRARY),
unit
Unit name of the device that the dataset will reside on.
Specifies a device group esoteric name, a generic device
type, or a specific device number. If you target a specific
device number, you must precede the device address with a
slash (/) character.
volumes
A list of comma separated volume serials. When
providing multiple volumes, processing will begin with
the first volume in the provided list. Offline volumes
are not considered. Volumes can always be provided when
not using SMS. When using SMS, volumes can be provided
when the storage class being used has
GUARANTEED_SPACE=YES specified. Otherwise, the
allocation will fail.
raw
Equivalent to the 'new' suboption for new dataset definitions, but
without using mvscmd default attributes. Use this for cases where
the called MVS program is able to assign its own default dataset
attributes.
For UNIX files:
blksize
Use the specified block size for the UNIX file being allocated.
This is necessary because UNIX files are normally treated as a
stream of bytes.
conddisp
Tells the system what to do with the UNIX file after abnormal
termination of the program.
May be 'keep' or 'delete'. Defaults to 'keep'.
filedata
The type of data that is (or will be) stored in the UNIX file.
May be 'binary', 'record', or 'text'.
lrecl
Use the specified logical record length for the UNIX file being
allocated. This is required in situations where the data is
processed as records.
The record length, block size and record format need to be supplied
because UNIX files are normally treated as a stream of bytes.
normdisp
Tells the system what to do with the UNIX file after normal
termination of the program.
May be 'keep' or 'delete'. Defaults to 'keep'.
pathmode
The file access attributes for the UNIX file being allocated.
Provide in chmod-like number format. (e.g. 0644, 1777)
If missing leading number assumes 0 (e.g. 644 == 0644)
recfm
Use the specified record format for the UNIX file being allocated.
This is necessary because a UNIX file is normally be treated as a
stream of bytes.
statusgroup
The status for UNIX file being allocated.
Specify up to 6 of: OCREAT, OEXCL, OAPPEND, ORDWR, ORDONLY,
OWRONLY, ONOCTTY, ONONBLOCK, OSYNC, OTRUNC.
Provide multiple attributes as comma separated list.
ENVIRONMENT VARIABLES
TMPHLQ
Overrides the current high-level qualifier used for temporary dataset names.
DESCRIPTION
mvscmd runs an unauthorized MVS program in the current shell. This is analogous to a job step in JCL. In addition, mvscmd lets you read input from stdin and write output to stdout, which is very convenient for running
mvscmd as part of a series of steps.
By default, mvscmd searches for the program (--pgm=<name>) in the linklist defined by the STEPLIB environmental variable. However, if you want to add a specific dataset to search for the program,
you can use --steplib=MY.DATASET to append this dataset to STEPLIB for this command. Users can display the list of datasets currently contained in STEPLIB by running the pll utility,
mvscmd is identical to mvscmdauth except for the name and that it runs unauthorized MVS programs instead of authorized MVS programs. For more details, see mvscmdauth.
