NAME
lastcomm
—
show last commands executed in reverse
order
SYNOPSIS
lastcomm |
[-w ] [-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.
-w
- Use as many columns as needed to print the output instead of limiting it to 80.
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 by user root 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 amount of cpu time used by the process (in seconds).
- The time the process started.
- The elapsed time of the process.
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(3), “C” indicates the command was run in PDP-11 compatibility mode (VAX only), “D” indicates the command terminated with the generation of a core file, and “X” indicates the command was terminated with a signal.
The “S” and “C” flags are no longer
recorded by the system, but will be reported by
lastcomm
when reading from an accounting file
generated by an older version of the system.
FILES
- /var/account/acct
- Default accounting file.
