lastcomm prints out information about previously executed
commands. If no arguments are specified, lastcomm will print
info about all of the commands in the acct file (the
record file). If called with a command name, user name, or tty name,
only records containing those items will be displayed. For example, to
find out which users used command ‘a.out’ and which users were
logged into ‘tty0’, type:
lastcomm a.out tty0
This will print any entry for which ‘a.out’ or ‘tty0’ matches
in any of the record's fields (command, name, or tty). If you want to
find only items that match ALL of the arguments on the command line, you
must use the '–strict-match' option. For example, to list all of the
executions of command ‘a.out’ by user ‘root’ on terminal
‘tty0’, type:
lastcomm --strict-match a.out root tty0
The order of the arguments is not important.
For each entry the following information is printed:
command name of the process
flags, as recorded by the system accounting routines:
S command executed by super-user
F command executed after a fork but without a following exec
C command run in PDP-11 compatibility mode (VAX only)
D command terminated with the generation of a core file
X command was terminated with the signal SIGTERM
the name of the user who ran the process
time the process started
3.1 Flags
This program implements the features of regular u*x lastcomm with
a few extra flags. When lastcomm is invoked without arguments,
the output looks like this:
nslookup jberman ttypb 0.03 secs Tue Feb 16 19:23
comsat root __ 0.03 secs Tue Feb 16 19:19
uptime ctilburg __ 0.11 secs Tue Feb 16 19:23
sh F ctilburg __ 0.02 secs Tue Feb 16 19:23
sleep ctilburg __ 0.02 secs Tue Feb 16 19:22
ls noel ttyp4 0.19 secs Tue Feb 16 19:23
--strict-match
Print only entries that match all of the arguments on the command
line.
--user name
List records for user with name. This is useful if you're trying
to match a username that happens to be the same as a command (e.g.,
ed).
--command name
List records for command name.
--tty name
List records for tty name.
-f filename
--file filename
Read from the file filename instead of the system's
acct file.
--ahz hz
Use this flag to tell the program what AHZ should be (in hertz).
This option is useful if you are trying to view an acct file
created on another machine which has the same byte order and file format
as your current machine, but has a different value for AHZ.
-p
--show-paging
Print paging statistics
--debug
Print verbose internal information.
--version
Print lastcomm's version number.
--help
Print lastcomm's usage string and default locations of system
files to standard output.
