Using , the simplest and readable solution ;)

perl -lne 'print ucfirst for split /\b/, lc' file

or :

perl -pe 's/\w+/\L\u$&/g'

Credits to Sundeep for this one

 Output

Abcde Xyag

 Explanations

print()      # do what you think
ucfirst()    # UPPER case the first letter
for()        # perform preceding calls for each element of following list
split(/\b/)  # split string on word boundaries
lc()         # lower-case each element from splited list

$ echo 'AbcDe xYaG' | sed -E 's/\w+/\L\u&/g'

  • -E to enable ERE
  • \w+ match one or more word characters, since longest match wins, entire words will be matched
  • \L\u& here \L will cause characters to be lowercased, but \u will override it and cause first character to be uppercase
