October 2, 2011, 11:59 pm

set environment variables from bash e.g:

1
2
export positionsfile="$outputfile".positions
export rankprogressfile="$outputfile"

Then use them from gnuplot e.g.:

1
2
3
4
5
6
7
8
set size 1,1
set ylabel "Count"
set xlabel "Positions"
 
set terminal postscript eps color
set output "`echo $positionsfile`.eps"
 
plot "`echo $positionsfile`" using 1:2 with lines
