[csw-users] about the path name

Wed Oct 3 18:36:19 CEST 2007

Thanks George for your thoughts on this.

When I did which for "svn" it just pointed towards /opt/csw/bin/svn and
didn't show any other path related to svn.

I also tried find / -name "svn" and even in this case it just lead me to the
/opt/csw/bin/svn

With all this in hand, I assumed that when I type svn, it should
automatically read from /opt/csw/bin/svn, which does not seem to be the
case.

I am guessing , when svn was uninstalled from the box from the location
/usr/local/bin the package might have left some mark somewhere and
therefore, when I type svn it is still trying to read from there.

Currently my path starts from /opt/csw/bin. But I wanted it in the end of my
path just because I wanted it to work no matter where I put this in my path,
thats all.

Thanks for all your help.
