|LASTCOMM(1)||General Commands Manual||LASTCOMM(1)|
NAME¶lastcomm - print out information about previously executed commands.
- [ command-name ... ]
[ user-name ... ]
[ terminal-name ... ]
[ --strict-match ]
[ --forwards ]
[ -f filename | --file filename ] [ --ahz hz ]
[ --user name ] [ --command name ] [ --tty name ]
[ | --show_paging ] [ --debug ] [ -V | --version ] [ -h | --help ]
DESCRIPTION¶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, type:
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 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
- 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.
- 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.
- --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
- Print verbose internal information.
- -V, --version
- Print the version number of lastcomm.
- -h, --help
- Prints the usage string and default locations of system files to standard output and exits.
