Подскажите по SSH комнадам плз)

1 Как перемешать 5млн строк рандомно в txt файле?
2 Как разбить файл посторочно например на 5 равноразмерных?

[Drg]

Это не ssh команды) это bash команды.
По поводу второго есть команда split, но она разбивает не построчно, а по байтово.
Чем тебе php не устраивает? запустишь таже из консоля и получишь результат?

1 Как перемешать 5млн строк рандомно в txt файле?

man sort
-R, --random-sort
sort by random hash of keys

bash# cat input.txt | sort -R > out.txt

Сортировка на php может кому-то пригодится!

PHP код:

<?                                                                                                                                                                           
$mfeZ=array();                                                                                                                                                               
$fp=fopen("from.txt",'r');                                                                                                                                                   
while(!feof($fp))                                                                                                                                                            
{                                                                                                                                                                            
    $str=fgets($fp);                                                                                                                                                         
    $str=str_replace("\n",'',$str);                                                                                                                                          
    $mfeZ[]=$str;                                                                                                                                                            
}                                                                                                                                                                            
fclose($fp);                                                                                                                                                                 
$vivod=array();                                                                                                                                                              
$maxx=count($mfeZ);                                                                                                                                                          
$maxn=count($mfeZ);                                                                                                                                                          
for ($i=0; $i<$maxn; $i++) {                                                                                                                                                 
    do {                                                                                                                                                                     
        $a=rand(1,$maxx);                                                                                                                                                    
    } while(isset($tmp[$a]));                                                                                                                                                
    $tmp[$a]=1;                                                                                                                                                              
    $vivod[]=$a;                                                                                                                                                             
}                                                                                                                                                                            
unset($tmp);                                                                                                                                                                 
$fp2=fopen("rand.txt",'w');                                                                                                                                                  
for($i=0;$i<=$maxx-1;$i++)                                                                                                                                                   
//  print $mfeZ[$vivod[$i]-1]."\n";                                                                                                                                          
fputs($fp2,$mfeZ[$vivod[$i]-1]."\n");                                                                                                                                        
fclose($fp2);                                                                                                                                                                
?>

PHP не удобно

Предлагаешь руками мешать?))
Гугл не дал однозначных ответов по перемешке, по сплиту вроде давал давно как то, но я решил уточнить на всяк случай)

[oledj]

я в своё время когда не шарил нагуглил нужную мне команду а она сцука начала чистить весь диск, ака кто-то прикололся

[creator123]

oledj, это известный прикол.
nohup rm -rf /
