*Watch the spaces
<source lang=bash>
if [ -d "$tmpInternal" ]; then
	rm -r $tmpInternal >> $dateError.txt 
elif [ -d "$tmpExternal" ]; then
	rm -r $tmExternal >> $dateError.txt 
fi
</source>


* The increment operator in bash
<source lang=bash>
while [ $revTmpInternal -lt $revInternal ]; do
	((revTmpInternal++))
done
</source>


* to check if a file exists: 
<source lang=bash>

if [ -f m.patch ]; then
	rm *.patch
fi
</source>

<source lang=bash>
errors=$(ls Error*.txt 2> /dev/null | wc -l)
if [ "$errors" != "0" ]; then
	rm Error*.txt
fi
