*
When scp ing a file which has white spaces in its name have to escape twice,

because it's escaped locally and then on the remote end.

There are a couple of options you can do (in bash):

scp user@example.com:"'web/tmp/Master File 18 10 13.xls'" .
scp user@example.com:"web/tmp/Master\ File\ 18\ 10\ 13.xls" .
scp user@example.com:web/tmp/Master\\\ File\\\ 18\\\ 10\\\ 13.xls .

Get the md5sum for files in a directory
----------------------------------------
$ ls | xargs md5sum

If the file name contains white space, set the delimiter to new line (default delimiter is white space)
$ ls | xargs -d'\n' md5sum

Estimate the directories / files size 
$ ls | xargs du -sh
