MD5 (no-spaces-here) = aaac9a687bd4ea9d2fc487e9cfb345f7

You could use find which avoids the subdirs:

find . -maxdepth 1 -type f -print -exec md5 {} \;

problems using ls with for_in (SH)

[Sdävtaker]

Im trying to get a file with all the md5 hashes of one directory.
My initial script was this:
#!/bin/sh
for file in $(ls)
do
   echo $file
   md5 $file
done

The problem is with the file names who contains whitespaces becouse 
the for_in passed each word as one iteration and not the full filename, 
I'd tried using -B in ls, but doesnt help.

Any idea what can i do?
Thanks!

Find the documetation, and look up the IFS environment
variable.

There's no need to call ls at all.  The shell can expand wildcards just
fine by itself:

 for file in * 
 do
echo $file
md5 $file
 done

but in your case, since md5 can take multiple filenames on its
commandline and prints the filename in its output:

 md5 *

will suffice.
