The praliases utility displays the current system aliases, one per line, in no particular order. The
special internal @:@ alias will be displayed if present.
The options are as follows:
-Cfile
Read the specified sendmail configuration file instead of the default sendmail configuration file.
-ffile
Read the specified file instead of the configured sendmail system aliases file(s).
If one or more keys are specified on the command line, only entries which match those keys are displayed.
The praliases utility exits 0 on success, and >0 if an error occurs.
