How can I automatically format a text file in Linux by a multi-occurring delimiter? -

-

i have string of unicode looks this:

%ue8fc%u0089%u0000%u8960%u31e5%u64d2%u528b%u8b30%u0c52%u528b%u8b14%u2872%ub70f%u264

(but much longer)

 

i'd automatically format it, making new line every 7 "%"s

the final formatting looks - able automatically format incredible - new line every 7 "%"s @ least enough

"%u8b30%u0c52%u528b%u8b14%u2872%ub70f%u264a" + "%uff31%uc031%u3cac%u7c61%u2c02%uc120%u0dcf" + "%uc701%uf0e2%u5752%u528b%u8b10%u3c42%ud001" +

is possible automate type of formatting command?

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
