lastcomm prints out information about previously executed commands.
If no arguments are specified, lastcomm will print info about all of
the commands in acct (the record file). If called with one or more
of command-name, user-name, or terminal-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 terminal). 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,
lastcomm --strict-match --command a.out --user root --tty 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
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
Print only entries that match *all* of the arguments on the
Print control characters.
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 ).
List records for command name.--tty name
List records for tty name.--forwards
Read file forwards instead of backwards. This avoids trying to
seek on the file and can be used to read from a pipe. This
must be specified prior to any -f arguments.
-f filename,--file filename
Read from the file filename instead of acct. A filename of
"-" will result in reading from stdin. This must either be the
first -f option, or --forwards must precede all -f options.
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
Print verbose internal information.
Print the version number of lastcomm.-h, --help
Prints the usage string and default locations of system files
to standard output and exits.
