I trying to write a UART(interfacing of serial devices) to linux machine but after I execute the following code to receive data I need to enter key (carriage return).... but I don't want to remove carriage return/enter key
i assumed :i insert mode would allow to simply back space, no appearently not? it seems none of the websites anywhere on earth mention how to delete a carriage return in vi.
I don't know if this is a configuration issue or a hardware issue, but I have a Kinesis Advantage USB keyboard and for some reason the F3-F5 keys aren't responding as they used to. They don't respond to anything and, when I tried using F5 on Emacs, it said <XF86AudioNext> is undefined, so I guess it's a weird mapping problem.
Any idea how I could remap them to the original meaning?
title's confusing, but can't edit it. I may not know what I'm talking about, but does anyone want to have a go at translating this suggestion I dug up into one that Mint 7 would act on?
I'm running Debian (Squeeze) and I have a toshiba portege m700. It has five buttons on the front just under the screen, which are the only ones accessible when you flip the screen over into tablet mode. One of them is for rotating the screen, and another is for switching to external display. I want to remap the remaining three to control, alt and super so that I can use shortcuts with the stylusThe problem is, when I used showkey to find out the key codes, I found out that each button generates more than one key code:Button 1:
key 126 press >> super_r, although this is distinct from the actual super key (125) key 7 press >> 6 key 7 release key 126 release
As a result of having mixed files from different filesystems, I have, in directory foo/, files with filenames in uppercase and files with filenames in lowercase. If I want to convert them to all uppercase how do I do it? Consider this will be later recorded into optical discs.
sometimes there are one, sometime there are two exchanges in this log file. the 100= is the stock exchange- if there are two, they are seperated by a comma. i understand how to escape a comma in a regex, but I am having trouble with combining it.
Need little advice running this command. watch -d 'ps aux | awk '{print $4" "$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr | head'
I get this error message from AWK. awk: cmd. line:1: {print awk: cmd. line:1: ^ unexpected newline or end of string
I have tried all the usual by trying to escape the single and double quotes in the command but same result. The end result should be the a listing of memory hungry processes that are scanned every 2 seconds (watch default value).
i have a cd that shows you an empty directory unless you mount it for the joliet extensions - specifically 25 2f 40. It uses wide characters with the high half null.
Is it possible to remove the ESC sequences in GNU Screen's output file? Things such as colours, tabs and other escape characters make their way into the log files and become difficult to decipher.
I've tried Dr. Google & Co. as well as reading the manual, but haven't been able to find anything suitable.Perhaps I've overlooked something?
When I started I took the defaults and ended up with Evolution.
I have never managed to get it set up to send. It and godaddy are on diffferent planets.
Having used Thunderbird in the past, I downloaded it and it automagically set itself up to send and receive.
So now I use Thunderbird - BUT - when I click on a link in an html page - the mailto macro sends me to something other than THunderbird - perhaps Evolution - and nothing gets sent.
So how do I tell the system that when i click a mailto in firefox I want Thunderbird?
PS I think I found it. In firefox - edit - preferences - applications tab - mmailto - it said Evolution. I changed it so say /usr/bin/thunderbird - will now test it.
YES - Seems that asking a question triggers my brain on how to resolve it. Sorry to waste your time.
I would like to replace gvim with vim in the terminal. One of the nice things about gvim is that it is able to display text using italics.
Vim allows setting an ANSI escape code for italics (e[3m), but this does not work in gnome-terminal. Is there a terminal emulator that supports the ANSI escape code for italics?
I am trying to use sed command to repalce one string with other but somehow replacement string contains forwards slash hence getting the error statement garbled!
Is there tool or a regexp that can convert shell escape characters to HTML code?
As an example, here is a logfile from GNU screen:
Which I would like to convert to something like this:
And send as HTML e-mail to an e-mail address, to archive my work.
Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.
The main thing I want to know is: how to translate my GUI actions into command-line code. I want to know if there is a command that outputs all the commands being made by interaction with my GUI.Say, for example that I type this command and then open a file, the terminal would then print: "gnome-open /{path to file}".(The reason I ask is because I need to know a command to open with a non-default program. I have downloaded MiniCopier, so I want to add a launcher for it to my panel, by figuring out the code to launch it, but the default app to open ".jar" files is archive manager, rather than Java, so "gnome-open" doesn't do the trick. I've even changed the default to Java and still "gnome-open" uses archive manager, while double-clicking will use the new default=java. Weird...)
I have 4 linux nat firewall boxes on 4 seperate networks all plugged into one WRT54G with the wireless function disabled. The WAN port is DHCP to my ISP modem (comcast.) WRT54G is set to gateway mode. WRT54G is not handing out IP's to clients, DHCP set to disable. Modem is a bridge and hands out dynamic internet routable ip addresses. All 4 linux boxes eth0 are static ip's and go to the WRT54g. Each Linux box is a dhcp nat firewalled router to my clients. Problem: DNS is not being resolved to my ISP from my clients. I can ping from a client to any where on the net or through my system. Tried placing the ISP DNS numbers in the /etc/resolv.conf file of servers but did not work.
Question does the WRT54G nat translate the ISP's DNS numbers also and to what? If so placing those numbers in the /etc/resolv.conf might solve the issue. Last bit of info. On one system there is 32 clients using win7 and dhcp. Some clients can surf all the time. Some never, some intermitently. IF I restart the server the above will applies to different clients. The same thing happens on the other 3 server systems. Attaching the Linux box directly to the modem and setting eh0 to DHCP I have no problems. I know it's not the linux boxes. It's placing the WRT54G between the modem and the Linux box that creates the loss of DNS resolution.
I've got a cisco error log which is pulled and mailed out via the following code (values are written to a mysql db). I really need to make the IP's in the second column hostnames,I don't really know how to start.I'll paste the code I've got and someone can come up with a bright idea
I'm following this guide : [URL]... to monitor SIP-connections on an Asterisk-server with Nagios. At some point the author mentions adding the following line to /etc/sudoers : nagios ALL= NOPASSWD: /usr/sbin/asterisk
