Install ns-2.27 with the prompt Bash: NS: Command not found

According to the installation, configuration, and tutorial of the smallko version NS2. when running the instance example2.tcl, the following error occurs: Bash: NS: Command not found.

 

Obviously, if the installation is successful and an error occurs during running, it must be caused by a path problem: ns. EXE cannot be found.

 

Modify the. bashrc file under C:/cygwin/home/administrator.

Right-click and use NotePad to openExport ns_home = 'pwd'/ns-allinone-2.27To:Export ns_home =/home/Administrator/ns-allinone-2.27
