Hi all,

I'm running on Redhat Linux 7.2 and very new to Unix command.
I had just downloaded Network Simulator 2.26.

I need to set this path "/home/junior/ns-allinone-2.26/bin", so that everytime I log in, I can start using my Network Simulator program.

How do I point my current path to this directory?

I understand that I need to modify my .bash_profile.
I can see .bash_profile when I do "ls -a", but how do I edit/open the content inside .bash_profile?

I did tried the following:

PATH=$PATH:"/home/junior/ns-allinone-2.26/bin"

But it still doesn't help. How do I use the commands "set path" and "export" to get the path going?

I had been struck at this for the past 2 weeks, please help....

thanks,
Junior

you don't need to set a PATH to run your program. just type:

/home/junior/ns-allinone-2.26/bin/<your binary here>

if you want to do it in a more "clever" way, you'd better create a /home/junior/bin directory, create a link to every executable you want to be able to run from anywhere into that directory and set the PATH variable to /home/junior/bin.

in your .bash_profile (usually it's only .bash or .profile, but that might be different on a redhat system) write:

PATH="/home/junior/bin:${PATH}"
export PATH

what command line are you using ?

if its bash, edit the file $HOME/.bash_profile

Hi,

I'm using bash as the command in Linux 7.2.

Sorry, I'm really new with this...what do you mean by <your binary here>?
/home/junior/ns-allinone-2.26/bin/<your binary here>

I manage to open my .bash_profile by using "view .bash_profile" command.
Inside the script reads....

PATH=$PATH:$HOME/bin

Should I edit the above to be......?
PATH=$PATH:$HOME/bin:/home/junior/ns-allinone-2.26/bin

How do I save whatever I type in the .bash_profile and make sure it points here the next time I log in?

I did tried to type the above in, but don't know how to save and get out of the program.

Junior
