Limiting the consecutive occurrence

[Pixel]

@Pixel:: I believe this is what you want:

Code:

A BUG found!

I don't what you people trying to do...
I'm just the scripting guy!! xD

EDiT:
"A BUG found!"
Try this one:

Code:

sed "/\(.\)\1\1/d;/\(.\).*\1.*\1/d;/\(.\).*\1.*\(.\).*\2/d;/\(.\).*\(.\).*\1.*\2/d"

That was quick, you are a sed scripting god M@LIK Thanks

M@LIK, it not working as I'd hoped

Code:

AABACDEF
AABACDEG
AABACDEH
AABACDEI
AABACDEJ
AABACDEK

breaks this rule

No more than 2 of any character within a single line


Edit: I got it working but can't be sure as I don't understand the command at all but notice you added

Code:

/\(.\).*\1.*\(.\).*\2/d

and

Code:

/\(.\).*\(.\).*\1.*\2/d

so I remove one of them. The command I using that seems to work is

Code:

sed "/\(.\)\1\1/d;/\(.\).*\1.*\1/d;/\(.\).*\1.*\(.\).*\2/d"

and output is

Code:

AABCDEFG
AABCDEFH
AABCDEFI
AABCDEFJ
AABCDEFK
AABCDEFL

these extra commands have slowed it down even more lol, shame they is no GPU version of sed or even a mulit-core version
