remove the last of all html files in a directory

plays with bash arrays. instead of storing the list of files in a temp file, this stores the list in ram, retrieves the last element in the array (the last html file), then removes it.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
for f in *.html; do sed '$d' -i "$f"; done

sed can be used deleting the last line and with -i option, there's no need to for temp files, the change is made on the actual file

for f in *.html; do head -n -1 $f > temp; cat temp > $f; rm temp; done

linuxrawkstar: Sunng meant removing the last line from each html file.

Sunng: it might be good to change the title if you can..
