NAME
printenv, env
— print out the environment, set
and print environment
SYNOPSIS
printenv |
[name] |
env |
[-] [name=value ...]
[command] |
DESCRIPTION
Printenv prints out the names and values of the
variables in the environment, with one name/value pair per line. If
name is specified, only its value is printed.
If a name is specified and it is not defined
in the environment, printenv returns exit status 1,
else it returns status 0.
Env executes command
after modifying the environment as specified on the command line. The option
name=value specifies an environmental variable,
name, with a value of value. The
option ‘-’ causes
env to completely ignore the environment it
inherits.
If no command is specified, env prints out
the names and values of the variables in the environment, with one
name/value pair per line.

HISTORY

3.0BSD.
BUGS
Env doesn't handle commands with equal
(``='') signs in their names, for obvious reasons.
