This gave me the impression you're using the Z shell.
The C shell says:
% vi!
vi!: Command not found.
And bash says:
$ vi!
bash: vi!: command not found
So the shell that says zsh should be the Z shell, or a different
shell that's just lying. :-)
with the bang stuff
if you do a
% !-3
you go back three vi cmds. !-N, N cmds.
Yes, this also works in C shell. You can use the h (or history)
builtin command to get an impression of content of the last commands
submitted to the shell.
At least in csh,
% !-1
equals
% !!
and repeats the last command.
You could use the following command to print the last 20 commands
with the relative number (-1, -2, -3 and so on) printed infront of
them:
% history 20 | awk 'BEGIN {cmds=20} { printf(\t%2d\t%s\n, -(cmds-i),
$0); i++ }'
It's probably a good idea to define an alias for that, like h20
(history of last 20 commands).
You could also use the zsh's equivalent of the precmd alias: It
is a command that will be executed prior to displaying the shell
prompt, so after you're done with a command, the last commands
(maybe shortened to 10, just substitute the two appearances of
the 20 to 10) will be displayed before the prompt appears;
this will make it easier (and save keystrokes) to check the last
commands and maybe repeat one.
Downside: The command pollutes the list of commands with itself,
so it should probably be grepped away.
% history 20 | awk 'BEGIN {cmds=20} { printf(\t%2d\t%s\n, -(cmds-i),
$0); i++ }' | grep -v history
It might be good to define a better exclusion pattern than just
history because that might lead to false-positives. I'd suggest
to rename the variables in the awk script to something unique and
then grep for those instead...
thankfully there are shortcuts!
And shell aliases. :-)
ps: zsh is sort of a ksh clone; I remember porting the zsh onto
my 286 in 1989. got a lot of csh-isms :)
The Z shell combines nice interactive features of the C shell
(to be correct: the tcsh) and the scripting features of sh and
bash. It's considered one of the most powerful shells. So it's
a wise move to use it, because it combines the _good_ things of
both worlds (and not the bad things, as the csh is a terrible
scripting shell, just as plain sh is an awful dialog shell).

That's probably correct, it reflects the sh-like aspects
of code (as I said, csh is a terrible scripting shell, and
this is also true regarding its configuration files). So
those entries look correct.
I'm not a zsh user, so I can't say this for sure. I'm heavily
infected with csh already. ;-)

The reason might be that the history, at this point in time,
did only contain 10 entries. I don't know how the content
of ~/.zhistory behaves if more than one shell is running
for a given user...
The Z shell is very customizable and can automate routine
tasks (regarding the shell dialog) in a pleasant manner.
If you want the last 10 commands to be displayed before the
shell prompt appears, try something like this in ~/.zshrc:
function precmd {
history 10 | awk 'BEGIN {histcmds=10} { printf(\t%2d\t%s\n,
-(histcmds-i), $0); i++ }' | grep -v histcmds
}
Not tested, but it seems to be much easier as zsh simply
defines a function precmd and doesn't require the user
to fight with quotes, doublequotes and escaping as csh
successfully does. :-)

The fc builtin can be helpful here. I like to see my recent history

commands:
# history without command numbers, look for optional pattern.
h () {
case $# in
0) fc -ln 1 | less +G ;;

If I dork up my history beyond belief, edit and reload the whole thing:
histedit () {
x=$HOME/.histedit
fc -W $x vi $x fc -R $x rm $x
}
In a previous message:
P % history 20 | awk 'BEGIN {cmds=20} ... | grep -v history
You can avoid some history pollution with these settings, at least in
ZSH version 4.3.10:
setopt histignoredups # don't store duplicate lines in command history
setopt histnostore # don't store history commands in history
Other settings I've found useful:
setopt autocd # go to a directory if first word on command line
# is not a command but is a directory
setopt autoresume # single-word commands may resume a suspended job
setopt cdablevars # allows cd'ing to a parameter

Ah, I see - you've been refering to repeating a _shell_ command (so the question was regarding the shell, which in your case is Z shell). You can probably use (like in the C shell) the arrow keys to browse the command history. Similarly, you can use the !number command refering to the command number obtained by the history command. There's a handy alias defined globally for the C shell: h which means history 25 (lists the last 25 commands), handy in regards of saving keystrokes. :-) I assume the zsh is also capable of filtered history: For example, you enter vi s and use the up and down arrow keys to browse all commands that have been entered starting with vi s (for example vi sent, vi stuff and so on). If the system's csh can do this, zsh should also provide this useful feature. And as your prompt pts/14 17:12 tao [5012] suggests, the command number is being shown. If this information is the same as the command number in the history, entering !5010 would execute the 2nd from last command. To repeat the last command, whatever it has been, !! can be used. Again, this works in csh, so I can't predict if it will work in zsh too, but I _assume_ it does. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

To repeat the last command, . can be used. The vi editor (and probably vim and gvim) supports according to man vi: [Vi]i[sual][!] [+cmd] [file] Vi mode only. Edit a new file. Is this what you're searching for? I THOGoHT it was !, but lookit: pts/14 17:11 tao [5010] vi sent pts/14 17:11 tao [5011] vi! zsh: command not found: vi! pts/14 17:12 tao [5012] ... this is vi == vim.

Ah, I see - you've been refering to repeating a _shell_ command (so the question was regarding the shell, which in your case is Z shell). You can probably use (like in the C shell) the arrow keys to browse the command history. Similarly, you can use the !number command refering to the command number obtained by the history command.
