MPE/iX Shell and Utilities Reference Manual, Vol 2

sort(1) MPE/iX Shell and Utilities sort(1)
PORTABILITY
POSIX.2. x/OPEN Portability Guide 4.0.
Available on all UNIX systems, with only UNIX System V.2 or later having the full functionality
described here.
The –M, –y, and –z options are extensions to the
POSIX standard. The POSIX.2 standard re-
gards the historical syntax for defining sorting keys as obsolete. Therefore, you should use
only the –k option in the future.
NOTES
The sortgen
AWK script is a useful way to handle complex sorting tasks. It is described in
the AWK Tutorial in the User’s Guide. It originally appeared in The AWK Programming Lan-
guage, by Aho, Weinberger, and Kernighan.
MPE/iX NOTES
The sort command provided in MPE/iX Shell and Utilities should not be confused with the
MPE/iX CI SORT command.
For more information on how the current MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
