I'm not sure I fully understand what you wrote. Do you want to catch the
output from gmx msd and store it in a file? If that's it, then you do
something like this:
gmx msd ... > filename 2>&1
The first ">" (or "1>") directs the standard output to the given file and
"2>" does the same thing but for the standard error. The extra "&1" tells
bash to store the latter in the same file as the standard output. In this
way, you're sure to store a faithful copy of the output you see in your
terminal in a text file.
To parse the file and get some values of interest, you can use a gazillion
different approaches. grep and/or awk would be good choices, but you don't
seem very confident with the terminal, so I guess it's better to stick with
a text editor.
