lastcomm(1) User Commands lastcomm(1)NAMElastcomm - display the last commands executed, in reverse order
SYNOPSISlastcomm [-f file] [-x] [command-name] ... [user-name] ... [terminal-
name] ...
DESCRIPTION
The lastcomm command gives information on previously executed commands.
lastcomm with no arguments displays information about all the commands
recorded during the current accounting file's lifetime. If called with
arguments, lastcomm only displays accounting entries with a matching
command-name, user-name, or terminal-name. If extended process account‐
ing is active (see acctadm(1M)) and is recording the appropriate data
items, lastcomm attempts to take data from the current extended process
accounting file. If standard process accounting is active, lastcomm
takes data from the current standard accounting file (see acct(2)).
If terminal-name is `- -', there was no controlling TTY for the
process. The process was probably executed during boot time. If ter‐
minal-name is `??', the controlling TTY could not be decoded into a
printable name.
For each process entry, lastcomm displays the following items of infor‐
mation:
· The command name under which the process was called.
· One or more flags indicating special information about the
process. The flags have the following meanings:
F The process performed a fork but not an exec.
S The process ran as a set-user-id program.
· The name of the user who ran the process.
· The terminal which the user was logged in on at the time (if
applicable).
· The amount of CPU time used by the process (in seconds).
· The date and time the process exited.
OPTIONS
The following options are supported:
-f file Uses file as the source of accounting data. file may be
either an extended process accounting file or a stan‐
dard process accounting file.
-x Uses the currently active extended process accounting
file. If extended processing accounting is inactive, no
output will be produced.
