SYNOPSIS
printenv [name]
DESCRIPTION
The printenv utility 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.
Some shells may provide a builtin printenv command which is similar or identical to this utility. Consult the builtin(1) manual page.
EXIT STATUS
The printenv utility exits 0 on success, and >0 if an error occurs.
SEE ALSO csh(1), env(1), sh(1), environ(7)STANDARDS
The printenv utility is provided for compatibility with earlier BSD and FreeBSD releases and is not specified by any standards. The func-
tionality of printenv can be duplicated with the echo(1) and env(1) utilities.
