I want to specify the output from text file in one command as below:

1-Print all lines that have all consecutive duplicates characters.
2-Print all lines with all consecutively repeated characters except the last one or the last two characters in the same line.
3-Print all lines with all consecutively repeated characters except the first one or the first two characters in the same line.
Example: 11122323 1112266 44778 223334456 6778811 845511 3357788

The output should be

1112266 >>>>> All repeated characters.
44778 >>>>> All repeated except the last character.
223334456 >>> All repeated except the last two characters
6778811 >>>> All repeated except the first character.
845511 >>>> All repeated except the first two characters.
Non consecutively repeating characters are allowed, but only if 1st or 2nd from start or end of a line. First line excluded becuse it has #3 is not consecutively repeated.

I have tried this command but it works even with not con
secutive duplicates characters.

awk '
split ("", N) # delete N array
P = 1 # reset boolean L used for print decision
L = length
for (i=1; i<=L; i++) N[substr($0, i, 1)]+=((i<3)

P # print if non-duplicate chars exist only at margins
