On top of what my esteemed colleagues already said: you should not need to do any cd in any script! Use absolute pathes whenever possible (that effectively means: always), this will always guarantee that the script works the same from whereever you call it.

Instead of i.e.

Code:

cd /some/where
for file in * ; do
     cp $file ../../some/where/else
done

Do it this way:

Code:

fSource="/some/where"
fTarget="/some/where/else"

for fFile in "$fSource"/* ; do
     fFile="${fFile##*/}"            # /some/where/filename -> filename
     cp "${fSource}/${fFile}" "${fTarget}/${fFile}"
done

I hope this helps.
