If you had gnuplot open when the power failure occurred, then it's possible that one of the gnuplot files got corrupted. If you want to get an idea of where the problem is (and if you have strace installed), do this

Code:

strace -o gnuplot.debug gnuplot

After gnuplot dies or is closed, open the file gnuplot.debug in a text editor. You may be able to sift through the messages (especially near the end of the file) to see what's causing the freeze.

It's very likely that re-installing gnuplot would all fix this, so you could just try that.

dear friend thanks for the reply. I have reinstalled gnuplot several time but the problem persists. i have run strace, i could not understand what is going wrong there. the end output is here

Ther is something broken or missing here ....

You should probably try
strace -f -o gnuplot.debug gnuplot

Look through the output for failed "open" calls and signal calls ... or post the whole thing.

Also delete
~/.gnuplot_history
and any other ~/.gnuplot* you find.

sorry i did not post full output of the command . i have attached it here the output of strace -o gnuplot.debug gnuplot

the output of strace -f -o gnuplot.debug gnuplot is in the file attached
