It code fragment needs aditionally movie15 package and you must use .u3d 3D format to insert your drawings.
Take care because no defined view is set in this code so your 3D desing could not apear in a right way.

A better .bash_history

To clean. bash_history

history | sort +1 | uniq -f 1 | sort -n| cut -c 8- > .bash_history.nodups

have a look, then move to .bash_history. Even better:

awk '!x[$0]++' .bash_history > .bash.tmp && mv .bash.tmp .bash_history

also add this to .bashrc:

export HISTCONTROL=ignoredups:erasedups

If you are inside a directory and want to check which job corresponds to it:

for i in $(qstat | awk '{print $1}'); do qstat -j $i | grep -q `pwd` && echo $i ; done
