Even lot of help commands are not working, and showing the same error page.

  1. Best Answer

    You should do export MANPAGER=less, check that /usr/bin/man wget works after this and if so look very carefully around your RC files for overrides for MANPAGER and PAGER.

  2. You can try to reinstall the man package : 

    yum reinstall man

    The error you are seeing makes me scared ... 2>/dev/null would send error messages to /dev/null (basically gone) Only very little good reasons to do this.

    Have you checked which man and checked if it was a binary ?
