Shell command descriptions

Following are the descriptions of all the commands for the z/OS shell. The descriptions are listed in alphabetic order. For instructions on how to read the command descriptions, see Reading the command descriptions.

The z/OS shell is based on the KornShell that originated on a UNIX system. As implemented for z/OS UNIX System Services, this shell conforms to POSIX standard 1003.2-1992.

Restriction: z/OS UNIX shell commands can only read a large format sequential data set that has no more than 65,535 tracks of data on any single volume.

This information assumes that your z/OS system includes Resource Access Control Facility (RACF®). Instead of RACF, your system could have an equivalent security product.
