ps - report a snapshot of the current processes.
参数说明：
-e Select all processes. Identical to -A.
-f Do full-format listing. This option can be combined with many other UNIX-style options to add additional
columns. It also causes the command arguments to be printed. When used with -L, the NLWP (number of
threads) and LWP (thread ID) columns will be added. See the c option, the format keyword args, and the
format keyword comm.
