===Tips===
*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 $revInternal ]; do
((revTmpInternal++))
done
</source>
* to check if a file exists:
<source lang=bash>
if [ -f m.patch ]; then
rm *.patch
fi
</source>
* To check if multiple files exist:http://www.ducea.com/2009/03/05/bash-tips-if-e-wildcard-file-check-too-many-arguments/
<source lang=bash>
errors=$(ls Error*.txt 2> /dev/null | wc -l)
if [ "$errors" != "0" ]; then
rm Error*.txt
fi
</source>
