Can someone please correct me whether I am using correct syntax with df ?

000001 //JOB11 JOB 1,NOTIFY=&SYSUID
000002 //REMOVE EXEC PGM=BPXBATCH,PARM='SH rm /z/t10981/mounts'
000003 //******************************************************
000004 //UNIX EXEC PGM=BPXBATCH
000005 //STDOUT DD DSN=&SYSUID..SK.OUTPUT(MST),DISP=SHR
000006 //STDERR DD SYSOUT=*
000007 //STDIN DD DUMMY
000008 //STDENV DD DUMMY
000009 //STDPARM DD *
000010 SH
000011 df -S
000012 /*

Thanks

That depends upon what you want the df command to do. If you wanted to display SMF accounting fields, then df -S will do so. If you wanted to do something else, then df -S is probably not the command to do that. Are you having some issue specifically (if so, what issue?) or are you just asking a general question?

Thanks for the reply.
Yes, I just want to display the below messages...
My requirement is to process df command with appropriate operand to write requested report for /z file system ONLY.

If I run the above job, i am getting rc=1
I am not 100% sure whether the use of 'df -S' codes (line no. 11 in above jcl) are correct ?

Mounted on Filesystem Avail/Total Files Status
Number of reads : 0
Number of writes : 0
Number directory I/O blocks : 0
Number read I/O blocks : 40
Number write I/O blocks : 0
Total number bytes read : 0x0 0
Total number bytes written : 0x0 0

Thanks

So use
Code:
df -S /z
Try it under OMVS first to make sure you're getting what you expect before you attempt to run it in batch.

I had a hard time starting to work on our USS until I found these publications.

the syscall commands: Using REXX and zOS UNIX System Services
the unix commands: z/OS UNIX System Services Command Reference

(Not limited to these two...)
