Dia bom!
Eu uso 'ps' para ver o comando que inicia o processo. A questão é que o comando é muito longo e o 'ps' não o mostra completamente.
Exemplo: Eu uso o comando 'ps -p 2755 | less 'e tem a seguinte saída
PID TTY STAT TIME COMMAND

Portanto, a linha de comando é muito longa e o comando para no meio da frase. Como posso ver tudo?
