    p\bpr\bri\bin\bnt\bte\ben\bnv\bv, e\ben\bnv\bv - print out the environment, set and print environment

    P\bPr\bri\bin\bnt\bte\ben\bnv\bv prints out the names and values of the variables in the environ-
    ment, with one name/value pair per line.  If _\bn_\ba_\bm_\be is specified, only its
    value is printed.

    If a _\bn_\ba_\bm_\be is specified and it is not defined in the environment, p\bpr\bri\bin\bnt\bte\ben\bnv\bv
    returns exit status 1, else it returns status 0.

    E\bEn\bnv\bv executes _\bc_\bo_\bm_\bm_\ba_\bn_\bd after modifying the environment as specified on the
    command line.  The option _\bn_\ba_\bm_\be=_\bv_\ba_\bl_\bu_\be specifies an environmental variable,
    _\bn_\ba_\bm_\be, with a value of _\bv_\ba_\bl_\bu_\be.  The option `-\b-' causes e\ben\bnv\bv to completely ig-
    nore the environment it inherits.

    If no command is specified, e\ben\bnv\bv prints out the names and values of the
    variables in the environment, with one name/value pair per line.

    E\bEn\bnv\bv doesn't handle commands with equal (``='') signs in their names, for
    obvious reasons.
