k
ksh(1) ksh(1)
inside a function, a new instance of the parameter name is created. The parameter value
and type are restored when the function completes. The following list of attributes can be
specified:
-L Left justify and remove leading blanks from value.Ifn is non-zero, it defines
the width of the field. Otherwise, it is determined by the width of the value of
first assignment. When the name is assigned, the value is filled on the right
with blanks or truncated, if necessary, to fit into the field. Leading zeros are
removed if the -Z option is also set. The -R option is turned off.
-R Right justify and fill with leading blanks. If n is non-zero, it defines the width of
the field. Otherwise, it is determined by the width of the value of first assign-
ment. The field is left-filled with blanks or truncated from the end if the param-
eter is reassigned. The -L option is turned off.
-Z Right justify and fill with leading zeros if the first non-blank character is a digit
and the -L option has not been set. If n is non-zero, it defines the width of the
field. Otherwise, it is determined by the width of the value of first assignment.
-f Cause name to refer to function names rather than parameter names. No
assignments can be made to the name declared with the typeset statement.
The only other valid options are -t (which turns on execution tracing for this
function) and
-x (which allows the function to remain in effect across shell pro-
cedures executed in the same process environment).
-i Parameter is an integer. This makes arithmetic faster. If n is non-zero, it
defines the output arithmetic base; otherwise the first assignment determines
the output base.
-l Convert all uppercase characters to lowercase. The uppercase -u option is
turned off.
-r Any given name is marked "read only" and cannot be changed by subsequent
assignment.
-t Tag the named parameters. Tags are user definable and have no special mean-
ing to the shell.
-u Convert all lowercase characters to uppercase characters. The lowercase -l
option is turned off.
-x Mark any given name for automatic export to the environment of subsequently
executed commands.
Using + instead of - causes these options to be turned off. If no name argu-
ments are given but options are specified, a list of names (and optionally the
values) of the parameters that have these options set is printed. Using
+
instead of - retains the values to be printed. If neither names nor options are
given, the names and attributes of all parameters are printed.
ulimit [n]Ifn is given, impose a size limit of n 512 byte blocks on files written by child processes (files
of any size can be read). If n is not given, the current limit is printed.
umask [mask]
The user file-creation mask is set to mask (see umask(2)). mask can either be an octal
number or a symbolic value as described in chmod(1). If a symbolic value is given, the new
umask value is the complement of the result of applying mask to the complement of the
previous umask value. If mask is omitted, the current value of the mask is printed. See
also umask(1).
unalias name ...
The parameters given by the list of names are removed from the alias list.
unset [-f ] name ...
The parameters given by the list of names are unassigned; that is, their values and attri-
butes are erased. Read-only variables cannot be unset. If the -f option is set, names
refer to function names. Unsetting ERRNO, LINENO, MAILCHECK, OPTARG, OPTIND,
RANDOM, SECONDS, TMOUT, and _ removes their special meaning even if they are subse-
quently assigned to.
% wait [job] Wait for the specified job to terminate or stop, and report its status. This status becomes
the return code for the wait command. If job is not given, wait waits for all currently
active child processes to terminate or stop. The termination status returned is that of the
last process. See Jobs for a description of the format of a job.
