ENV(1) BSD Reference Manual ENV(1)
env - set and print environment
env [-i] [name=value ...] [utility [argument ...]]
env executes utility after modifying the environment as specified on the
command line. The option name=value specifies an environment variable,
name, with a value of value.
The options are as follows:
-i Causes env to completely ignore the environment it inherits.
If no utility is specified, env prints out the names and values of the
variables in the environment, with one name=value pair per line.
If the utility is invoked, the exit status of env shall be the exit
status of utility; otherwise, the env utility exits with one of the fol-
lowing values:
0 The env utility completed successfully.
1-125 The exit code returned from the utility.
126 The utility specified by utility was found, but could not be in-
voked.
127 The utility specified by utility could not be found.
execvp(3), environ(7)
The historic - option has been deprecated but is still supported in this
implementation.
The env utility conforms to IEEE Std 1003.2-1992 ("POSIX.2").
env doesn't handle commands with equal ('=') signs in their names, for
obvious reasons.
