So basically you are asking, "is my login shell bash or ksh?" And if there is no bash on your system it will be ksh, because that is the default, else you will have changed it by the time your regular .profile has been installed. Your SHELL variable will be set to your login shell and bash, from version 2 at least, will have the BASH_VERSION variable. So, either:
Code:
[ -n "$BASH_VERSION" ] && . ./.bashrc

or
Code:
case "$SHELL" in
*bash) . ./.bashrc ;;
*ksh) . ./.kshrc ;;
esac

should do it.

Do older systems not like this? Is that what you were saying with portably?

Code:
if [[ -s ~/.bashrc && /usr/bin/bash ]]; then
    #echo hi
    source ~/.bashrc;
fi

POSIX shell and older shells don't support the double square bracket operator; and the single square bracket operator doesn't support the && and || operators. Personally, I think it's more readable to keep one expression per square bracket operator, whether it is single or double.

rpccp_remove_profile

remove profile(1m)														remove profile(1m)

NAME

       remove profile - Removes all profile elements and the profile from the specified name service entry

SYNOPSIS

       rpccp remove profile  profile-entry-name [-s syntax]

OPTIONS

       Indicates  the  name  syntax of the entry name (optional). The only value for this option is the dce name syntax, which is the default name
       syntax. Until an alternative name syntax becomes available, specifying the -s option is unnecessary.

ARGUMENTS

       Indicates the name of the target profile.  For an entry in the local cell, you can omit the cell name and specify  only	the  cell-relative
       name.

DESCRIPTION

       The  remove  profile  command  removes a profile (and all of its elements) from the name service database. The entry name of the profile is
       required.

   Privilege Required
       You need write permission to the CDS object entry (the target profile entry).

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLES

       The following  commands	run  RPCCP  and  remove  the  profile  named  /.:/LandS/anthro/molly_o_profile:  $  rpccp  rpccp>  remove  profile
       /.:/LandS/anthro/molly_o_profile

RELATED INFORMATION

       Commands: add element(1m), remove element(1m), show profile(1m)

																remove profile(1m)
