LASTCOMM(1) BSD General Commands Manual LASTCOMM(1)NAMElastcomm — show last commands executed in reverse order
SYNOPSISlastcomm [-w] [-f file] [command ...] [user ...] [terminal ...]
DESCRIPTIONlastcomm gives information on previously executed commands. With no
arguments, lastcomm prints information about all the commands recorded
during the current accounting file's lifetime.
Option:
-f file Read from file rather than the default accounting file.
-w Use as many columns as needed to print the output instead of
limiting it to 80.
If called with arguments, only accounting entries with a matching command
name, user name, or terminal name are printed. So, for example:
lastcomm a.out root ttyd0
would produce a listing of all the executions of commands named a.out by
user root on the terminal ttyd0.
For each process entry, the following are printed.
· The name of the user who ran the process.
· Flags, as accumulated by the accounting facilities in the sys‐
tem.
· The command name under which the process was called.
· The amount of cpu time used by the process (in seconds).
· The time the process started.
· The elapsed time of the process.
The flags are encoded as follows: “S” indicates the command was executed
by the super-user, “F” indicates the command ran after a fork, but with‐
out a following exec(3), “C” indicates the command was run in PDP-11 com‐
patibility mode (VAX only), “D” indicates the command terminated with the
generation of a core file, and “X” indicates the command was terminated
with a signal.
The “S” and “C” flags are no longer recorded by the system, but will be
reported by lastcomm when reading from an accounting file generated by an
older version of the system.
