Is there a way to show what the history number would be of the command I'm typing in the prompt? For example, I frequently run commands then run 'history' to pull up the history number of a command I want to repeat. Then I do [ESC] -> [history #] -> [g] to get my previous command. If I could show the history numbers in my prompt, this could cut out having to run history over and over again.

I had started writting my own custom libraries on an AIX 4.2. Before finishing, I wanted to do a very simple test. So I wrote the followings:

ZZ=testz "aa" "bb"
echo "$ZZ"
exit 0
testlib.sh
testz () {
return "$1$2"
}
When I ran my test.sh, I got an... (2 Replies)

Hello,
I have this problem:
I have a server to which I ssh, and it has a special prompt request. The prompt is done by a ?prompt command.
It is fine with SSH, since the prompt I guess gets some input, but when I use SCP, the copy always fails.
So, I was wondering if there is maybe a... (1 Reply)

Any idea how to do it???
Many thanx. (2 Replies)
I am facing a situation where when there are lesser users, i am able to login to the AIX server. If the number of users increase - the login prompt is getting delayed. Sometimes even timeout occurs.

So Yesterday I switched from Solus Linux to Fedora Linux 30, but I forgot to backup some of my dotfiles including kshrc.

history
history(n) Tcl Built-In Commands history(n)
__________________________________________________________________________________________________________________________________________________NAME
history - Manipulate the history list
SYNOPSIS
history ?option? ?arg arg ...?
_________________________________________________________________DESCRIPTION
The history command performs one of several operations related to recently-executed commands recorded in a history list. Each of these
recorded commands is referred to as an ``event''. When specifying an event to the history command, the following forms may be used:
[1] A number: if positive, it refers to the event with that number (all events are numbered starting at 1). If the number is negative,
it selects an event relative to the current event (-1 refers to the previous event, -2 to the one before that, and so on). Event 0
refers to the current event.
[2] A string: selects the most recent event that matches the string. An event is considered to match the string either if the string
is the same as the first characters of the event, or if the string matches the event in the sense of the string match command.
The history command can take any of the following forms:
history
Same as history info, described below.
history add command ?exec?
Adds the command argument to the history list as a new event. If exec is specified (or abbreviated) then the command is also exe-
cuted and its result is returned. If exec isn't specified then an empty string is returned as result.
history change newValue ?event?
Replaces the value recorded for an event with newValue. Event specifies the event to replace, and defaults to the current event
(not event -1). This command is intended for use in commands that implement new forms of history substitution and wish to replace
the current event (which invokes the substitution) with the command created through substitution. The return value is an empty
string.
history clear
Erase the history list. The current keep limit is retained. The history event numbers are reset.
history event ?event?
Returns the value of the event given by event. Event defaults to -1.
history info ?count?
Returns a formatted string (intended for humans to read) giving the event number and contents for each of the events in the history
list except the current event. If count is specified then only the most recent count events are returned.
history keep ?count?
This command may be used to change the size of the history list to count events. Initially, 20 events are retained in the history
list. If count is not specified, the current keep limit is returned.
history nextid
Returns the number of the next event to be recorded in the history list. It is useful for things like printing the event number in
command-line prompts.
history redo ?event?
Re-executes the command indicated by event and return its result. Event defaults to -1. This command results in history revision:
see below for details.
HISTORY REVISION
Pre-8.0 Tcl had a complex history revision mechanism. The current mechanism is more limited, and the old history operations substitute and
words have been removed. (As a consolation, the clear operation was added.)
The history option redo results in much simpler ``history revision''. When this option is invoked then the most recent event is modified
to eliminate the history command and replace it with the result of the history command. If you want to redo an event without modifying
history, then use the event operation to retrieve some event, and the add operation to add it to history and execute it.
