That won't be necessary, but there's no particular guarantee that all of
your files are in sync, because of the system's I/O buffering.

information useful to you, however your answers really are there in the
man page of trjconv. However, unless you happen to have exactly one
.trr, .pdb and .tpr file in your working directory, your shell globs
will not work. Only a handful of tools in GROMACS permit such multiple
I/O and trjconv is not one of them. You can tell by the suffix "Input,
Mult." on the man page... viz
-f traj.xtc Input, Mult.
Generic trajectory: xtc trr trj gro g96 pdb"
Next, as the header of each man page indicates, only the flags that
label the inputs get hyphens, not both the flags and their input data.
This allows the code to distinguish flags from inputs to flags.
