SYNOPSIS

lastcomm [commandname] ... [username] ... [terminalname] ...

DESCRIPTION

lastcomm gives information on previously executed commands. If no arguments are speciﬁed,

lastcomm prints information about all the commands recorded in the accounting ﬁle,

/var/adm/pacct during the current accounting ﬁle’s lifetime. If called with arguments, only account-

ing entries with a matching command name, user name, or terminal name are printed. For example, to

produce a listing of all executions of commands named a.out by user root on terminal ttyd0 use:

lastcomm a.out root ttyd0

For each process entry, the following are printed.

• Name of the user who ran the process.

• Flags, as accumulated by the accounting facilities in the system.

• Command name under which the process was called.

• Amount of cpu time used by the process (in seconds).

• What time the process started.

Flags are encoded as follows:

S Command was executed by a user who has appropriate privileges.

F Command ran after a fork, but without a following exec.

D Command terminated with the generation of a core ﬁle.

X Command was terminated with the signalSIGTERM.
