Thanks, bakunin. I'm new to the Korn shell, so had no idea about these nuances. I see that ksh93 is in the OpenBSD package repository, so I'll install it and see how it's different from pdksh.
Neo, I will give VSC/IntelliSense a try. If it makes CPP easier to read and work with, I will probably really like it.
In the meantime, I'm back to bash for when I want to work and not play/explore. I find that having this in my .bashrc gives me exactly the behavior I expect (namely, any time I press Enter in a terminal, the shell's idea of the history matches exactly what is in my HISTFILE--no more, no less):
Code:
PROMPT_COMMAND="history -a; history -c; history -r"
hello everyone!
Very basic question for the guru's in here but anyways, I am trying to type a command that is longer than the line. What character do I use to continue my command on the next line?
Thanks in advance....

I have to make some modifications to it.

What is the command for checking modification history on file?

Let me rephrase this. On a regular Unix file can I at least check to see the time and date history modification of the file? (6 Replies)

Hello :)
I'm a newb when it comes to shell scripting and was wondering about a command(s) for a script that could be used to checkout a certain number of version/revision histories of a file. I know for the latest revison you "co filename" or for a certain revision number "co -r*.* filename"... (2 Replies)

The system has been rebooted and I need to see the commands executed in the system prior to restart by the oracle user.The history command is not showing me the commands executed prior to reboot.
Please advise.

I am making a bash script right now and am running into an issue. As I am new to scripting, I do not know exactly what to do to get what I'm looking for in my script.
Essentially, my script will automatically input VRFY common names after nc

prunehistory
PRUNEHISTORY(8) System Manager's Manual PRUNEHISTORY(8)NAME
prunehistory - remove file names from Usenet history file
SYNOPSIS
prunehistory [ -f filename ] [ -p ] [ input ]
DESCRIPTION
Prunehistory modifies the history(5) text file to ``remove'' a set of filenames from it. The filenames are removed by overwriting them
with spaces, so that the size and position of any following entries does not change.
Prunehistory reads the named input file, or standard input if no file is given. The input is taken as a set of lines. Blank lines and
lines starting with a number sign (``#'') are ignored. All other lines are should consist of a Message-ID followed by zero or more file-
names.
The Messge-ID is used as the dbz(3) key to get an offset into the text file. If no filenames are mentioned on the input line, then all
filenames in the text are ``removed.'' If any filenames are mentioned, they are converted into the history file notation. If they appear
in the line for the specified Message-ID then they are removed.
Since innd(8) only appends to the text file, prunehistory does not need to have any interaction with it.
OPTIONS -p Prunehistory will normally complain about lines that do not follow the correct format. If the ``-p'' flag is used, then the program
will silently print any invalid lines on its standard output. (Blank lines and comment lines are also passed through.) This can be
useful when prunehistory is used as a filter for other programs such as reap.
-f The default name of the history file is /var/lib/news/history; to specify a different name, use the ``-f'' flag.
EXAMPLES
It is a good idea to delete purged entries and rebuild the dbz database every so often by using a script like the following:
ctlinnd throttle "Rebuilding history database"
cd /var/lib/news
awk 'NF > 2 {
printf "%s %s %s", $1, $2, $3;
for (i = 4; i <= NF; i++)
printf " %s", $i;
print "
";
}' <history >history.n
if makehistory -r -f history.n ; then
mv history.n history
mv history.n.pag history.pag
mv history.n.dir history.dir
else
echo 'Problem rebuilding history; old file not replaced'
fi
ctlinnd go "Rebuilding history database"
