In addition to the good advice given by others, I did want to mention
that cpptraj has some limited wildcard support.

The trajin and parm commands both understand file wildcards (*, ?), so
assuming 'ls *_?.mdcrd' gives you the order you want you could do:

trajin *_?.mdcrd

Any other keywords you provide to 'trajin' (start, stop etc) will be
applied to all files selected this way.

Not at this time.

Hope this helps,
