The version of gnuplot in RedHat6.2 misses two convenient features 1. file name completion 2. command line editing if the line is longer than the width of the terminal This is an annoying deletion!
gnuplot got compiled accidentally with it's own readline instead of the standard one; this is fixed in the gnuplot in rawhide.
the rawhide solution is not a solution, since the new gnuplot binary depends on a slightly higher version of ncurses. Please be so kind and provide an errata upgrade rpm, which does not require the upgrade of 25 other packages to rawhide !! regards
we will be providing an errata for this item for 6.2 shortly.
