But, if I do something like 'ls file*.dat | xargs myscript.sh' gnuplot runs through all of the plots without waiting for me to press enter.

So, gnuplot is getting something from stdin effectively making my pause commands useless.

Any ideas would be greatly appreciated.

Thanks in advance.
Maybe ls ...| xargs ... is not needed, but if that's the case, then try:

Code:
printf "%s\n" file*.dat | xargs -n1 -p myscript.sh

Also the pause -1 records might need to be removed from the gnuplot command file.
