I'm running a ksh script that requires user interaction, and said users (myself among them) may get a little trigger happy and get ahead of ourselves and accidentally key in the wrong responses to future prompts in the script.
Naturally, I'd like to prevent that, so how does one clear that buffer prior to the ensuing read command?
Hello friends! i am writing a code in which i take inputs (numbers) from user and count the total number of positive, negative and zeros entered. I need to clear my standard input buffer before scanf() command. My compiler is completely ignoring the fflush(stdin) command. its not even showing any... (1 Reply)
Hi, I've got a bit of a ridiculous problem and wasn't sure where to post it.
I need to use the vertical bar for piping in Bash but, as per the title, am using a UK layout on a US (physical) keyboard which doesn't have a key for it in the place I'd expect. I've tried using xbindkeys and Unicode... (7 Replies)

Hello,
I am having trouble clearing the serial port buffer using the iclear and iflush commands. The code runs without errors being returned, but when I check the buffer again there is still data.
The only way I have so far is to read until there is nothing left in the buffer. Shouldn't one... (1 Reply)
hi,
i have an unix command which is as follows:
ctmfw /work/CDFC/landing/ZORC.txt CREATE 0 60 1 10 240
I think a txt file called ZORC gets created in the mentioned directory, i am not sure what 0 60 1 10 240 is. Is my understanding correct and also let me know what those numbers denote?... (4 Replies)
When I worked with client-server (socket) programming, I encountered "the socket error# 10055" which means "No buffer space available". This might be a symptom of one or more applications that didn't return system resources (like memory) properly. Temporary solution was to reboot the machine to... (7 Replies)

I have PC users who use an emulation to login to the Solaris

How can I change the keyboard mapping of the Sun keyboard

dpkg-trigger(1) dpkg suite dpkg-trigger(1)NAME
dpkg-trigger - a package trigger utility
SYNOPSIS
dpkg-trigger [option...] trigger-name
dpkg-trigger [option...] command
DESCRIPTION
dpkg-trigger is a tool to explicitly activate triggers and check for its support on the running dpkg.
This can be used by maintainer scripts in complex and conditional situations where the file triggers, or the declarative activate triggers
control file directive, are insufficiently rich. It can also be used for testing and by system administrators (but note that the triggers
won't actually be run by dpkg-trigger).
Unrecognized trigger name syntaxes are an error for dpkg-trigger.
COMMANDS --check-supported
Check if the running dpkg supports triggers (usually called from a postinst). Will exit 0 if a triggers-capable dpkg has run, or 1
with an error message to stderr if not. Normally, however, it is better just to activate the desired trigger with dpkg-trigger.
-?, --help
Show the usage message and exit.
--version
Show the version and exit.
OPTIONS --admindir=dir
Change the location of the dpkg database. The default location is /var/lib/dpkg.
--by-package=package
Override trigger awaiter (normally set by dpkg through the DPKG_MAINTSCRIPT_PACKAGE environment variable of the maintainer scripts,
naming the package to which the script belongs, and this will be used by default).
--no-await
This option arranges that the calling package T (if any) need not await the processing of this trigger; the interested package(s) I,
will not be added to T's trigger processing awaited list and T's status is unchanged. T may be considered installed even though I
may not yet have processed the trigger.
--no-act
Just test, do not actually change anything.
ENVIRONMENT
DPKG_ADMINDIR
If set and the --admindir option has not been specified, it will be used as the dpkg data directory.
