I was given a title "Modelling of Liposomes for drug delivery system" as my final year project. Hence, my supervisor introduces Linux to us which we are not familiar with at all as we are Windows user. Anyway, he gave us a brief tutorial on VMWare and the commands to install gromacs. I successfully installed VMWare, however, Im stucked here now. Where am I supposed to type in the commands? Is it at the terminal? When Im at the terminal, I see this: [root@localhost~]# Am I at the right track? I jotted down the commands. It's as follows:

cd Desktop/
1s [Is it 1(one)s/l(L)s/I(i)s?]
cd xmgrace
1s
cd_..
cd xmgrace
1s
cd grace-5.1.22/
1s
./configure
make
make install
./xmgrace

I double check with my friend, and she gave me a totally different command instead:

cd desktop
1s
cd gromacs
cd fftw-3.2.1
1s
./configure--enable-float
make
make install
cd..
1s
cd gromacs-4.0.5
1s
./configure
make

Any idea which is the right one? When i try installing the commands at terminal, I receive this msg "bash: Is: command not found"

Im very confused and not sure how else to proceed. Do advise. Thank you very very much in advance

OK, so gromacs is a Linux distribution for something to do with fourier transforms and the likes? ok, well the "ls" command is ls as in "list the files in this directory". It's really hard to know what you're really trying to do here. Clearly you're looking to compile and install some software from source code, but if this source code is not in the directory you're trying to work in, naturally you're not going to get the result you're after.

In general we don't know what gromacs is, what fftw is (i guess i'm roughly right there) or xmgrace / grace... and whether they exist or not, so that side we can't comment on too much. but as above, the "ls" command will always work in a bash window if you're typing in L S in lower case.
