Count lowercase in a word - Shell Programming and Scripting

Hi,

I have a similar problem where i need to count stretches of lower- and upper-case letters within words like

ttgggcTGGCCGCCCCCCAGggc
ttgggcTGGCCGCtgggcttCCCCCAGggc

the output could look like:

ttgggcTGGCCGCCCCCCAGggc lower 5 upper 12 lower 3
ttgggcTGGCCGCtgggcttCCCCCAGggc lower 5 upper 7 lower 6 upper 6 lower 3

any help would be appreciated,

best
robert

I'd like to print out the 1st word followed by the number of lowercase characters in that word. The words only consist of a few letters.

I was trying something like

awk '{a+=gsub(a,a) b+=gsub(b,b) c+=gusb(c,c) d+=(gsub(
d,d) x=(a+b+c+d) END {print $1, X}' infile >outfile

Thanks so much for your help.
