I am trying to use gnuplot for visualization of data stored in a file which is dynamically changed during computations. My aim is visualization of data from this file every several seconds during computations. How can I refresh gnuplot output produced in the bash script (usually i call gnuplot in the pipe). In web I found this solution:
!echo "pause 1; replot; reread;" > loop_forever.gnu load "loop_forever.gnu"
But I am new in bash scripting. What does > mean and what is .gnu file?
