The man pages are installed in the /usr/sunvts/man directory. To access the man pages, follow these steps to add this directory to your MANPATH variable in the initialization that corresponds to your login shell. (usually, .profile for the Bourne and Korn shells or .login for the C shell).
For Bourne or Korn shell:
export MANPATH= /usr/share/man:/usr/man:/usr/sunvts/man
For C shell:
setenv MANPATH /usr/share/man:/usr/man:/usr/sunvts/man
# echo $MANPATH /usr/share/man:/usr/man:/usr/sunvts/man
