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 com-
mand-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, 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 exited
Print only entries that match *all* of the arguments on the com-
List records for user with name. This is useful if you’re try-
ing to match a username that happens to be the same as a command
(e.g., ed ).
List records for command name.
List records for tty name.
-f filename, --file filename
Read from the file filename instead of acct
Print verbose internal information.
Print the version number of lastcomm.
Prints the usage string and default locations of system files to
standard output and exits.
