General :: Keyboard Won't Pipe?
Dec 23, 2010
I'm on the command line, as the install for the proprietary ATI driver has failed. I'm following the instructions for troubleshooting here but the pipe "|" key is not working - a tilda "~" shows up when I press it.I'm wondering if this is because of the keyboard being set as UK instead of US? I did have to change this setting at the graphical login initally, whether from choosing this setting by mistake or the installer choosing it automatically when I chose English UK for the language.

This is my Keyboard layout (Norwegian layout on a US keyboard on a HP Mini 1000), but I just can't find the combination to hit when I need to pipe (> <) things.
Can anyone help me find the combination so I can use my netbook for more than just simple browsing?

I'm new to linux, been using fedora 12 for about a week. I just noticed a problem with my keyboard layout. When i press the key with the backslash and pipe character, i get < for backslash and > for the pipe character. I have tried the following to fix the problem:
1.$ gnome-keyboard-properties then selected the proper keyboard model (Asus Laptop) tried adding different keyboard layouts and setting them as default nothing i did there made any difference.I am currently using USA, i have tried Canada English, USA international, and more I noticed that even when i change it to something like Afganistan, there is no noticable different when i type in the test area. I notice that there are keyboard layouts that have < and > where the backslash and pipe character should be, but the picture for USA shows the pipe and backslash where they should be.

I've written a simple server in linux used fork to create a FIFO pipe.The server create two FIFO pipe.One for server read data from client and write data to client.Then another pipe for client read data from server and write data to server.When the server read data from a client used server-pipe and then write data to client.But ,if the client no read open the pipe,the server side write will be crashed because of a broken-pipe SIGPIPE. How to check whether the read side is opened?Or,how to catch the SIGPIPE,and then my server will still execute on,not crashed!!

I'm doing ping between 2 RH servers through a VPN site2site tunnel and in some times I got in the result pipe 2 and another pipe 3 as I mark it in blue color below.
e.g.
64 bytes from 192.168.1.10: icmp_seq=0 ttl=128 time=0.229 ms
64 bytes from 192.168.1.10: icmp_seq=1 ttl=128 time=0.287 ms
64 bytes from 192.168.1.10: icmp_seq=2 ttl=128 time=0.278 ms
[code]....
What's the difference between pipe 2 and pipe 3 and what's the meaning of it?

We want to kill a process provided that only process name is given and we are to first find out the process id and then kill the process. Yes, in one go! That is, using pipe.

I have a text file containing the URL I wanted for mplayer to play. Currently, I play those in commend line using the following steps:
1)cat playlist
2)use mouse to highlight the link
3)type: mplayer then click both left/right mouse button
I was hoping if I can do this in comment line without mouse. I've tried the following without luck. (assume there's only 1 address in the text file)
1) cat playlist |mplayer
2) cat playlist |awk '{print $1}'| mplayer

I don't quite understand how pipes work in bash. I know that it takes an output from one command as the input in another command. What an output is I can get because it's what the command prints out to the screen. But how do I know what input a command will take? Here is an example I thought would work:
Which gem | rm
Unfortunately it didn't.
Which gem prints out "/usr/bin/gem" so that must be the output right? I thought that was given to rm so it would be "rm /usr/bin/gem" but I was wrong. How do I know what input a command takes?

I have two Linux processes communicating via a nameless pipe. How can monitor the traffic in the pipe? How can I inject data into the pipe? I have root access and know the pipe inode.

I'm storing a list of strings in a file and would like to read the file and pipe each line returned to grep which in turn searches a directory for files containing the string.However this is not returning any output.

Two processes are communicating through a pipe: A | B. A is writing data faster than B is reading it in. Is there any way to have A limit its writing rate to match B's reading rate?
AFAIK the pipe will get full, and will make A's writing block, waiting for B to read in more data. But is there a way to limit A's writing rate before the pipe fills up? (In a way it's like having a pipe with a really small capacity, but as far as I know pipe capacity is a constant compiled into the kernel.)
Code:
EXAMPLE FOR CLARIFICATION
Right now the command is printing out the following in 1-second intervals:
But with flow control it should print out (again in 1-second intervals):
...since "date" would block on the writing loop due to the slow reading loop.

I have an OLED screen on my laptop that I have configured to show status information. The current driver I have installed in Linux for it is able to display messages by sending them to a script as an argument separated by spaces.Example: the command /opt/asusg50oled/utils/notify.sh Hi Everybody "Hello World" displays on the oled screen:
Hi
Everybody
Hello World
If another message is sent before the old ones disappear and it reverts to status info, it pushes off the top message. Example: less than 30 seconds after the previous example, /opt/asusg50oled/utils/notify.sh "Bananas have potassium" is executed:
Everybody
Hello World
Bananas have potassium
What I want to do is have kernel messages (the kind you see by running dmesg) forwarded to this script. For example, when I insert a USB drive, the following information would show on the OLED screen as they're logged:........

I am tying to read a file in with nawk whilst trying to take input from a pipe. I've come across the getline option and no matter how hard I try, I can't figure out the correct syntax. What I want to do is to take some input from the pipe and make a comparison with all of the values in a file and print a match.

In a terminal in OSX I can pipe output to pbcopy and then go into a web browser and paste it. I tried this in Linux with xcopy but when I switch to the browser it just overwrites the clipboard with with whatever was in it the last time the browser was used. What works like pbcopy in Linux?

After running the following command, I get:
[root@yukiko /]# find / -iname .bashrc
/home/clamav/.bashrc
/home/vpopmail/.bashrc
/etc/skel/.bashrc
/root/.bashrc
But I would like to have a command that prints a specific line by supplying the command with the line number, for example:
[root@yukiko /]# find / -iname .bashrc | getline(2)
/home/vpopmail/.bashrc
Is there such a command on CentOS?
