Korn shell only. Assign a type to each variable (along with an optional initial value ), or, if no variables are supplied, display all variables of a particular type (as determined by the options). When variables are specified, - option enables the type and + option disables it. With no variables given, - option prints variable names and values; + option prints only the names.

Options

-f[ c ]

The named variable is a function; no assignment is allowed. If no variable is given, list current function names. Flag c can be t , u , or x . t turns on tracing (same as set -x ). u marks the function as undefined, which causes autoloading of the function (i.e., a search of FPATH will locate the function when it's first used). x exports the function. Note the aliases autoload and function .

-H

On non-UNIX systems, map UNIX filenames to host filenames.

-i[ n ]

Define variables as integers of base n . integer is an alias for typeset -i .

-L[ n ]

Define variables as flush-left strings, n characters long (truncate or pad with blanks on the right as needed). Leading blanks are stripped; leading 0's are stripped if -Z is also specified. If no n is supplied, field width is that of the variable's first assigned value.

-l

Convert uppercase to lowercase.

-R[ n ]

Define variables as flush-right strings, n characters long (truncate or pad with blanks on the left as needed). Trailing blanks are stripped. If no n is supplied, field width is that of the variable's first assigned value.

-r

Mark variables as read-only. See also readonly .

-t

Mark variables with a user-definable tag.

-u

Convert lowercase to uppercase.

-x

Mark variables for automatic export.

-Z[ n ]

When used with -L , strip leading 0's. When used alone, it's similar to -R except that -Z pads numeric values with 0's and pads text values with blanks.
