Thankfully, you can do both on z/OS at the same time :-)
// EXEC PGM=COZBATCH (A better BPXBATCH)
//SYSUT1 DD DISP=SHR,DSN=HLQ.MY.DATA
//STDOUT DD SYSOUT=*
//STDIN DD *
# This is just a z/OS UNIX login shell in batch...
fromdsn //DD:SYSUT1 | grep ^ted013: | awk -F':' '{print $3}'
//
COZBATCH is available free under our Community license.
