I'm using "du -mc" to get the size of each directory. But then i'm trying to limit that list to one level deep.
But i couldnt find the proper grep syntax to do that.

Filtering the du -mc output to echo only lines that has one slash, would do the trick ... but how ?!

du -mc | grep "/"

the last command isnt filtering anything (obviously)
And man grep gives cryptic help on the subject :

       A regular expression may be followed by one of several repetition oper-
       ators:
       ?      The preceding item is optional and matched at most once.
       *      The preceding item will be matched zero or more times.
       +      The preceding item will be matched one or more times.
       {n}    The preceding item is matched exactly n times.
       {n,}   The preceding item is matched n or more times.
       {n,m}  The  preceding  item  is	matched at least n times, but not more
	      than m times.

i've tried

du -mc | grep "/"{1}

but doesnt output anything at all, then
