You miss the point
The -s switch scans a file for the line beginning with the (specified text)
now make you test and see
/write -stsoglanos29 test.txt tsoglanos29
/write -stso test.txt tso
/write -stsoglanos293 test.txt tsoglanos293
and you will realise one more nick is just add and not
replaced, I holp u accept this becuse it is a fact ...
There is always one more bug...
