z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

Options
Usage Note
–f Specifies attributes of functions.
–H Performs file mapping from POSIX to the host name.
–i[number]
Marks each variable as having an integer value, thus making arithmetic
faster. If number is given and is nonzero, the output base of each variable
is number. The default is decimal.
–l Converts uppercase characters to lowercase in any value assigned to a
variable. If the –u option is currently turned on, this option turns it off.
–p Writes output to the coprocess. This option is not currently implemented.
–r Makes each variable read-only. See readonly.
–t Tags each variable. Tags are user-defined, and have no meaning to the
shell. For functions with the –f option, this turns on the xtrace option. See
set for a discussion of the xtrace option.
–u Converts lowercase characters to uppercase in any value assigned to a
variable. If the –l option is currently turned on, this option turns it off.
When used with –f, the –u option indicates that the functions named in the
command line are not yet defined. The attributes specified by the typeset
command are applied to the functions once they are defined.
–x Sets each variable for automatic export. See export.
The last three options that follow justify, within a field, the values assigned to each
variable. The width of the field is number if it is defined and is nonzero; otherwise,
the width is that of the first assignment made to variable.
–L[number]
Left-justifies the values assigned to each variable by first removing any
leading blanks. Leading zeros are also removed if the –Z option has been
turned on. Then blanks are added on the end or the end of the value is
truncated as necessary. If the –R flag is currently turned on, this option
turns it off.
–R[number]
Right-justifies the values assigned to each variable by adding leading
blanks or by truncating the start of the value as necessary. If the –L flag is
currently turned on, this option turns it off.
–Z[number]
Right-justifies values assigned to each variable. If the first nonblank
character of value is a digit, leading zeros are used. See also the –L option.
typeset is a built-in shell command as well as a separate utility.
typeset
An autoloaded function is defined (loaded) by the /bin/sh shell when invoked as a
command name, it’s not already defined to the shell, and the function definition file
is found in a directory specified in the FPATH variable. (For more information see
“Command Execution” on page 556 under the sh command.) To replace an
autoloaded function, use the unset -f name command. The next time the function
name is invoked, the FPATH search will find the new version.
