    But when I again open the terminal.It shows me error :
    ns command not found
    similiar command is ‘nc’

    again I have to install NS2 and source .bashrc and in next step i have to validate
    again the NS2.34 gets install.

    If I close the terminal and again opens it then again the error (above error) comes out.

    Please help for the same and guide me for the same

  4. the file is available in the /home/username

  5. sir i got error like this while installing ns-2.34 in fedora14 pls tell me wat to do for complete installation.

  6. Mr Pradeep, isnt there a way to just upgrade from ns2.34 to ns2.35. Because I have added some new protocols in 2.34. So, without wasting time, isn't there a simpler way ?

  7. No update for ns 2.35 is available. But with the help of patch file it is possible.

after the installation, set the PATH, MANPATH and INFOPATH as suggested by LATEX

export PATH=$PATH:/usr/local/texlive/2019/bin/x86_64-linux
export MANPATH=/usr/local/texlive/2019/texmf-dist/doc/man
export INFOPATH=/usr/local/texlive/2019/texmf-dist/doc/info

put these lines in to the /home/pradeepkumar/.bashrc

$] gedit /home/pradeepkumar/.bashrc
We have installed TexLive 2019 and texstudio.

To install texstudio
