] | Assuming that all files with `-n` is a copy and that you don't want the thumbs either, this works in KornShell (ksh), and also in Bash with the `extglob` option set (`shopt -s extglob`):
```
for f in !(*_thumb.png|*-[1-9].png); do
g=${f%.png}-1.png
test -f $g || echo $f
done
``` | If it's only "-1" that determines it's a copy, then you have no copy of your 2-1.png
or 2-1\_thumb.png files either. If that's your matching criteria and you want the thumbs tested as well, you can do
```
for i in `ls |grep -v "\-1" | cut -f1 -d.`; do
if `echo $i | grep thumb > /dev/null`; then
test -f ... |

This could be more perfoment because you dont need two subselects. |

Firefox does not seem to even know that the java plugin is there (it is installed, and re-installed), i.e., it does not show up in Firefox's tools -> addons -> plugins, nor does it run. (It did, until some recent update.-) | 2012/01/06 | [

Update of my recent post:
I had the same problem as reported by lloyd allison after the recent update on the Ubuntu 10.04 64-bit system. The problem was compounded but the presence of the NoScript (2.2.6) plugin (which I like ;).
The solution was:
a) disable NoScript and stop firefox
