Very easy : Delete any ns2 *PATH text added to .bashrc .
1. Your ns-2.35 with no changes :
$ cd ns-allinone-2.35/ns-2.35/
$ sudo make install ( 'make install' will copy 'ns' to /usr/local/bin/.)
$ cp ns ns235-orig ( This is your backup of the original 'ns'.)
$ sudo cp ns235-orig /usr/local/bin/
2. The "ns-2.35" with <added-protocol>
$ cd ns-allinone-2.35/ns-2.35/
$ cp ns ns235-protocol-name
$ sudo cp ns235-protocol-name /usr/local/bin/
... All simulations will work with $ ns-any-name file.tcl
*
* You can have an infinite number of ns-allinone builds installed at the same time.
