NAME

env, getenv, setenv − environment routines

SYNOPSIS

env

getenv varname

setenv varname [ value ]

DESCRIPTION

The env command prints out the current process’s environment as a list of variables and their current values. 

The getenv command prints out the current value of the variable whose name is given as the argument varname .  If the variable is not set, a blank line is output. 

The setenv command sets the value of the variable whose name is given as the argument varname to value when the latter is provided on the command line. If no second argument is given the effect is to unset the variable. In both cases, if the variable is set originally, that value will be replaced by the new one.
