PRINTENV 1 ""
C NAME
printenv - print out the environment
env - set and print out the 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.

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