Qual usuário está executando a maioria dos processos?

Question

Meu top é assim:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

Você pode ver que o mesmo "USER" pode ter vários "COMMAND" sendo executados como "php-cgi". Gostaria de descobrir qual usuário está executando a maioria dos processos e obter uma contagem de quantos processos estão sendo executados.

    

Answer 1

Use ps . De man ps :

-U userlist
Select by real user ID (RUID) or name. It selects the processes whose real user name or ID is in the userlist list. The real user ID identifies the user who created the process, see getuid(2).

-u userlist
Select by effective user ID (EUID) or name. This selects the processes whose effective user name or ID is in userlist. The effective user ID describes the user whose file access permissions are used by the process (see geteuid(2)). Identical to U and --user.

Então, por exemplo, para ver todos os processos do usuário asjzdiwq , você pode usar:

ps -u asjzdiwq  ## Using RUID
ps -U asjzdiwq  ## Using EUID

    

Answer 2

Para contar todos os processos por usuário:

ps -eo user|sort|uniq -c|sort -n

ou apenas para aqueles com php-cgi:

ps -eo user:15,cmd|sed -n '/php-cgi/s/ .*//p'|sort|uniq -c|sort -n
