Hardware :: USB Device As Pipe Between Two Hosts
Jan 10, 2010I am wondering if we can with Linux create a pipe between two hosts (linux of course), so when I plug an USB disk on host1 it will be mounted on host2.

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 trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?

Probably an easy (which means stoopid) question...I am trying to reroute a website using my hosts file so that it matches my servers certificate file for testing without effect dns and the live site.When I went to edit my /etc/hosts file it is non-existent. I have, I am assuming in it's place, hosts.allow and hosts.deny. Can anyone explain why I do not have a hosts file?

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.

View 4 Replies View RelatedI'm new to Linux and I'm still trying to make my linux work on an external drive. I think I have found how, but I need to use the pipe symbol in a command line and I don't have it on my keyboard.I've tried different settings for my keyboard and different language, but nothing seems to do; I try all the keys, with shift or alt, but nothing works.I'm working on Debian, Lenny, with a Lenovo 3000 v100 Laptop. Nowhere on my keyboard do I have the symbol I am looking for. I have the vertical bar divided in two, but not the continous one.Do I need somehow to remap my keyboard or add a function to a key?

I understand that $! is the PID of a command. For example:
Code: #!/bin/bash
myprogram &
echo "PID of myprogram is $!"
I'd like to send the output of "myprogram" to both console and to a log file using the "tee" command but I also want to store the PID of "myprogam". Something like this:
Code: #!/bin/bash
myprogram | tee ./logfile &
echo "PID of myprogram is $!"
The problem is that $! is now the PID of "tee" rather than the PID of "myprogram".
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 am trying to automate some directory naming when we're manually running some scripts and are using tee to direct the output to a file (log). Right now this is what we do
Code:
./some_script.sh 2>&1 | tee /home/user/some_dir/logs/manual/some_script_20110216_1628.log
As a matter of laziness and keeping the log files consistently named, I'd like to create a function to pipe it to so that it's doing all the naming How I envision the command running
Code:
./some_script.sh 2>&1 | myfunc
And what the logfile name should look like (and in the right directory)
Code:
some_script_20110216-1628.log
I was thinking of adding a function to our profile to handle this. Just in testing I was trying to stream line right on the command line, but I'm having some difficulty in getting the name of the script that is pushing data over the pipe. Here is what I've tried
Code:
./some_script.sh 2>&1 | tee $(cd ../logs/manual; pwd)/$0_$(date +%Y%m%d)-$(date +%H%M).log
but that created a file named
"bash_20110216-1628.log"
For instance, suppose I want to pipe the output of ps -A to a gtkdialog table.

View 2 Replies View RelatedI 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?
