NAME
envvar — standard environment variables
SYNOPSIS
export NAME=value
set NAME=value
echo $NAME
DESCRIPTION
envvar -- Miscellaneous Information
When a process is executed, it inherits a set of strings called the environment. It is conventional for
these strings to have the form:
NAME=value
The export command built into the MKS KornShell can be used to set the variable NAME into the
environment of every child process. The set command built into command.com or cmd.exe does
the same. The echo command prints the value of environment variable NAME inside the MKS
KornShell.
Note:
The shell maintains additional shell variables that are not exported to child processes;
because these variables are not passed on, they are not environment variables.
The following environment variables are used throughout MKS Toolkit:
COLUMNS
If you set this variable to a numeric value, various commands use its value as the width of
the output device in columns. This overrides the default.
COMSPEC
The value of this variable must point to the standard command interpreter (command.com or
cmd.exe), if you want to use that command interpreter in any way. This variable is called
ComSpec under Windows NT/2000/XP/2003.
