Here's another way to keep track of open files: lsof ~/tmp/lyx_tmpdir3909cEWtW6/lyx_tmpbuf0/thesis.* COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME kghostvie 4428 dfreeman 13r REG 9,0 107171924 3004525 /home/dfreeman/tmp/lyx_tmpdir3909cEWtW6/lyx_tmpbuf0/thesis.ps gs 4838 dfreeman 13r REG 9,0 107171924 3004525 /home/dfreeman/tmp/lyx_tmpdir3909cEWtW6/lyx_tmpbuf0/thesis.ps gs 4839 dfreeman 13r REG 9,0 107171924 3004525 /home/dfreeman/tmp/lyx_tmpdir3909cEWtW6/lyx_tmpbuf0/thesis.ps kpdf 5039 dfreeman 13r REG 9,0 6475882 3004856 /home/dfreeman/tmp/lyx_tmpdir3909cEWtW6/lyx_tmpbuf0/thesis.pdf So kghostview keeps it in use, kpdf does too. But kdvi doesn't, of course :) To test for kghostview and kpdf, then, call `lsof filename` and if it returns an empty string it's not being viewed anymore. Maybe this can be one more attribute of the viewer configurations - method of checking if it is still in use. One could then use custom shell scripts for more complex tests. Have fun, Darren
