Hi,
Thank you all for helping me to solve this problem.The reason for getting
"bash: ns: command not found" error was trying to run NS by typing "ns", not
"./ns".
Now I can use NS and also NAM by going to their directories in Cygwin
prompt which is a little bit hard, especially for those who categorize their
projects in different directories.I have added both NS and NAM directories
to my PATH (in .bashrc) correctly but the response to echo $PATH differs
from what i defined in .bashrc.
When the PATH is " PATH=$PATH:${NSHOME}/ns-2.35:${NSHOME}/nam-1.15 " I get
the following response in the answer to echo $PATH
mo...@mobin ~
$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/cygdrive/c/Program Files/PC Connectivity
Solution/
:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/W
bem:/cygdrive/c/Program Files/Intel/WiFi/bin/:/cygdrive/c/Program
Files/Microsof
t SQL Server/90/Tools/binn/:/cygdrive/c/php5:/cygdrive/c/Program
Files/MySQL/MyS
/nam-1.15/home/Mobin/ns-allinone-2.35-RC6-2.35-RC6
To simplify PATH for debugging I removed $PATH in PATH and changed it this
way:
PATH=${NSHOME}/ns-2.35:${NSHOME}/nam-1.15
and with this value for PATH environment variable, echo $PATH prints this:
mo...@mobin ~
$ echo $PATH
/nam-1.15/home/Mobin/ns-allinone-2.35-RC6
Which doesn't sounds correct to me.do you have any idea about this?
Thanks,
Mobin
