A solution to you “I/O problem” is to write all the temporary files, including the PS file to a “virtual disk” (remember those?). If you make sure that GMT_TMPDIR is on a virtual disk and you run everything in your script like this . gmt_shell_functions.sh gmt_init_tmpdir ps=$GMT_TMPDIR/output.ps step1 -K > $ps step2 -O -K >> $ps stepn -O >> $ps ps2raster -Tg -A -P -E300 -D$GMT_TMPDIR $ps mv $GMT_TMPDIR/*.png . gmt_remove_tmpdir Then you have no disk I/O caused by intermediate files.
