Como eu digo 'ps' para usar todas as colunas disponíveis?

Question

Para especificar colunas, posso usar a opção ps de -o :

ps -o pid,cmd

Como posso dizer a ps para gerar todas as colunas disponíveis?

    

Answer 1

ps é um comando muito dependente do sistema. Então a resposta dependerá da variante do Unix que você está usando.

Com o ps da versão 3.3.3 do procps-ng no Linux:

ps -eo "$(ps L|cut -d' ' -f1 | grep -vx thcount)" | less -S

(por algum motivo, thcount aparece na lista de campos conhecidos, mas não é aceito como argumento para -o . nlwp está OK).

Você terá muitas duplicações, pois muitos desses campos são aliases para a mesma coisa (ou formas diferentes de expressá-la. Por exemplo, você realmente não precisa de start quando tiver lstart ).

Para os cabeçalhos de coluna exibirem o seletor de campo em vez do cabeçalho normal (para ajudá-lo a refinar qual coluna você deseja):

ps -eo "$(ps L|sed -n '/thcount/!s/\([^ ]*\).*/=/p')" | less -S

Os campos especificados por POSIX são args, comm, etime, grupo, nice, pcpu, pgid, pid, ppid, rgroup, ruser, time, tty, user e vsz. Então você pode usar

ps -eo args,comm,etime,group,nice,pcpu,pgid,pid,ppid,rgroup,ruser,time,tty,user,vsz

Para um comando que deve funcionar em todos os sistemas compatíveis.

    

Answer 2

ps axo pid,tid,class,rtprio,ni,pri,psr,pcpu,stat,comm,cmd,stat,euid,ruid,tty,tpgid,sess,pgrp,ppid,tt,user,fname,tmout,f,wchan

Você deve escolher a lista acima.

como:
