I did quote early on in this thread that some terminals do not respond correctly to some terminal escape codes. Some of those escape codes will not work at all.
So in the first part the outside parentheses create an array in advanced shells like bash so therefore longhand:
As for the second 'printf' line, changing the values 24 and 80 to say 30 and 120 will expand the terminal size on certain terminals, (xterm as an exmaple), to that size for the duration of that terminal session. Of course calling it again with 24 and 80 restores it back to the original.
IF and a big if, it doesn't work then many of those terminal commands in the URLs won't work either.
I want to get the screen width and cursor positions.
When I used curses, all the screen content was cleared.
So Can I use curses to get the screen size without clearing anything in the window?
Or is there any other alternative???
I can use only C or C++. (0 Replies)

Hi to all!

hi all,
am trying to modify a ksh script to group server names together depending on the cluster they sit in. currently the script does a

I need to get the cursor position, and put it inside a variable. Problem is, i don't have the tput command, or ncurses.
Apparently I was supposed to try the following:
echo -e '\E
But I don't get a value or anything. Please help. (3 Replies)
Hi there.
It's easier to explain this with a pseudo code, I hope this makes sense:
var1=hello
echo $var1
some kind of loop
echo loop counter
done
How do I hold the cursor position immediately behind the last output so I'd get something like:
hello123456789
DOS used to use ","... (5 Replies)

getlogin_r
getlogin(3C)getlogin(3C)NAME
getlogin(), getlogin_r() - get name of user logged in on this terminal
SYNOPSIS DESCRIPTION
The function retrieves the name of the user currently logged in on a terminal associated with the calling process, as found in user-
accounting database maintained by utmpd(1M).
At least one of the standard input, standard output, or standard error must be a terminal. For the first of these found that is a termi-
nal, a user must have logged in on that terminal, and that terminal must be the controlling terminal of the session leader process of the
calling process's session.
The function can be used in conjunction with to locate the correct password file entry when the same user ID is shared by several login
names.
The recommended procedure to obtain the user name associated with the real user ID of the calling process is to call and if that fails, to
call
To get the user name associated with the effective user ID, call
performs the same operations as but returns the login name in the buffer to which buf points, whose size in bytes should be passed in
buflen. buf should have space for the name and the terminating null character. The maximum size of the login name can be obtained using
the API with as the argument.
APPLICATION USAGE
The return value from points to static data whose content is overwritten by each call.
RETURN VALUE
Upon successfully finding and validating the login name of the user logged in on the terminal, returns a pointer to the name. Otherwise,
it returns a null pointer, and sets to indicate the error.
Upon successfully finding, validating, and copying to the buffer the login name of the user logged in on the terminal, returns 0 upon suc-
cess and returns an error number upon failure.
ERRORS
and fail if any of the following is true:
[EACCES] Access permission to get the status of the terminal device file, was denied.
[EMFILE] Too many file descriptors are in use by this process.
[ENFILE] Too many file descriptors are in use on the system.
[ENOENT] The terminal device file cannot be found.
[ENOTTY] None of the standard input, standard output, or standard error is a terminal, or for the first of these that is a
terminal, no current login is registered on that terminal, or the session leader process of the calling process has
no controlling terminal.
[EPERM] One of the standard input, standard output, or standard error is a terminal, and a current login was found on that
terminal, but that terminal is not the same as the controlling terminal of the session of the calling process.
[ESRCH] The session leader process of the calling process is no longer running.
The error condition associated with [EPERM] prevents processes that have access to some other user's terminal from believing that they are
related to that other user's login session.
also fails if the following is true:
[ERANGE] The length of the name to be returned, including the terminating null byte, exceeds buflen.
