NAME

functions — display or modify shell functions

SYNOPSIS

functions [–tux] name name ...

DESCRIPTION

functions lets you modify the attributes of the functions speciﬁed by the list of names in

the command line. It is a built-in alias of sh(1) deﬁned with

alias functions=’typeset -f’

If no function names are speciﬁed, functions displays all currently deﬁned functions with

the attributes speciﬁed by the options. If no options are given, functions lists all currently

deﬁned functions.

Options

functions accepts the following options:

–t turns on the xtrace option for the given functions. See set(1).

–u allows you to specify attributes for functions which are not yet deﬁned.

–x marks a function for automatic export. See export(1).

DIAGNOSTICS

Possible exit status values are:

0 Successful completion.

1 Failure due to an invalid command line argument.

If you use the command to display the values of variables, the exit status value is the number

of names that are invalid.

Messages
