-e     Select all processes.



-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.
