NAME
lastcomm
- show last commands executed in reverse order
SYNOPSIS
lastcomm
[-f file
]
[command ...
]
[user ...
]
[terminal ...
]
DESCRIPTION
Lastcomm
gives information on previously executed commands.
With no arguments,
lastcomm
prints information about all the commands recorded
during the current accounting file's lifetime.
Option:
- -f file
-
Read from
file
rather than the default
accounting file.
If called with arguments, only accounting entries with a
matching
command
name,
user
name,
or
terminal
name
are printed.
So, for example:
lastcomm a.out root ttyd0
would produce a listing of all the
executions of commands named
a.out
or by user
root
or on the terminal
ttyd0
For each process entry, the following are printed.
-
The name of the user who ran the process.
-
Flags, as accumulated by the accounting facilities in the system.
-
The command name under which the process was called.
-
The number of pagefaults that occured when running the process.
-
The amount of cpu time used by the process (in seconds).
-
The time the process exited.
The flags are encoded as follows: ``S'' indicates the command was
executed by the super-user, ``F'' indicates the command ran after
a fork, but without a following
exec,
``D'' indicates the command terminated with the generation of a
core
file, and ``X'' indicates the command was terminated with a signal.
FILES
- /var/log/acct
-
Default accounting file.
