What is the command used to check the pid of all the processes current running in Linux environment?
Answers
Solution:
On every UNIX-like operating system, the process status command (ps) displays information about active processes. Every operating system's version of ps is slightly different, so consult your documentation for specific options.
This documentation describes a version of ps common to many distributions of Linux. It accepts several kinds of options:
UNIX options, which may be grouped and must be preceded by a dash ("-").
BSD options, which may be grouped and must not be used with a dash.
GNU long options, which are preceded by two dashes ("--").
Options of different types may be freely mixed, but might cause conflicts. There are some synonymous options, which are functionally identical, due to the many standards and compatible ps implementations.
