NAME

declare - define or print variables

SYNOPSIS

declare [ATTRIBUTE_OPTION...] [-p] [NAME[=VALUE]...]

DESCRIPTION

Declare variables and/or give them attributes. If no NAMEs are given then display the values of variables. The -p option will display the attributes and values of each NAME. When -p is used with NAME arguments, additional options are ignored. When -p is supplied without NAME arguments, it will display the attributes and values of all variables having the attributes specified by the additional options. If no other options are supplied with -p, declare will display the attributes and values of all shell variables.

Please refer to the Variables section for the list of pre-set variables.

ATTRIBUTE OPTIONS

-x
Mark NAMEs for export to subsequent commands via the environment.

Using '+' instead of '-' turns off the attribute instead. If both '+' and '-' are specified for the same attribute, that attribute is turned off.

OPTIONS

-p VARIABLE
Prints the value of a variable.

EXAMPLES

Let us first declare a variable using the declare command

declare myvar="This is FluidShell"

To change the default prompt in FluidShell, use the below command:

declare prompt=$

declare sql_variable=1

To declare the number of statements to be kept in memory:
