is there any way by which the cat command can be made to behave like less or more?i.e when less or more used with a text file as argument, will display the file 1 page at a time, allowing us to navigate through the file.So any way for cat to display the file 1 page at a time?P.S : I don't want to pipe the output of cat to less or more.

I have a file in a directory mysite/a.php on machine A and machine B. The files will not have any difference initially.On machine A if a.php is changed and then when a sync is done from machine B to A, will a.php have the change or will it be overwritten? What about directories?

View 1 Replies View RelatedI switched to zsh, but I dislike the completion. If I have 20 files, each with a shared prefix, on pressing tab, zsh will fully complete the first file, then continue going through the list with each press of tab. If I want one near the end, I would have to press tab many times.
In bash, this was simple - press tab and I would get the prefix. If I continued typing (and pressing tab), bash would complete as far as it could be certain of. I find this behavior to be much more intuitive but prefer the other features of zsh to bash.
Is there a way to get this style of completion? Google suggested setopt bash_autolist, but this had no effect for me (and no error message was printed upon starting my shell).
I am compiling some c++ code trying to connect it with libi2cbrdg.a library where I have a lot of functions. So when I am doing this gcc -g rand.c -lasound -li2cbrdg -o rand.I don't have missed functions instead I have some other C/C++ connected errors, when I am using g++ compiler like this g++ -g rand.c -lasound -li2cbrdg -o rand.it does not see functions inside that library but everything fine with c++ code.How can I make g++ behave like gcc in this case?

I have a 6+2 disk RAID5 array. If I do mdadm --detail, it shows me 6 active, working 8, failed 0 and spare 2, as expected. However, in Disk Utility, it tells me I have two arrays, the one I expect, but with 6+1; and another with no disks. When I look through my disks, I see there's one which is 'different'. While I had made all my 8 disks partition-less, this one seems to have developed a partition somehow - "Linux RAID autodetect". Also, when I click on 'Go to array', it takes me to this other odd diskless array.
How can I get my disks to behave themselves?
(Also, I think these disks seem to move around devices for some reason).
some days ago I upgraded my 10.04 Ubuntu to 10.10. Upgrading took quite some time as I had already witnessed in previous upgrades. Everything seems to work fine after this operation but for the Grub. I can no longer set the timer! It means I have to manually push "Enter" to start booting. I also noted that I cannot change the font size of the Grub any longer. I have not seen such behaviour during previous upgrades (I started upgrading with U 9.04).

In my corporate environment, I'm required to run a Windows machine that acquires a VNC session on a machine in the server farm. My windows machine is dual head with different resolution monitors ( 1600x1080 on left and 1920x1200 on right). If I create a VNC session that spans the monitors, then maximizing a window in the VNC session causes it to stretch across both my monitors.
Instead, I want a "maximize" event to behave like it does on my windows machine -- I only want to maximize to the display that the window is on.
How can I define what, what I'll call, "maximize regions"? Regions in the VNC graphical plane where when I click "maximize", the window only expands to the region it currently ( and mostly) resides in.
Can I do this in gnome, X, xrandr, or some other magical interface?
I just set up NIC bonding in Ubuntu 10.4, following these instructions, and I've got it working except for one problem: Every time I up or down a network device, or every time the system reboots, my routes go all to hell with eth0 and eth1 entries next to my bond0 entries. When the eth0 and eth1 entries show up, my connection is hosed and I have to go in via the maintenance IP to kill each route one at a time, leaving only bond0. Here's how I want my routes to look at all times:
Code:
Kernel IP routing table

possible to make a flashdrive behave like keyboard. I recon there must be some good reasons not to. Because I can imagine some situations where this comes in verry handy.For example a script that executes gives login tab password enter and readies the next login for the next computer.This way I could just plug the flashdrive in, let type, plug it out and continue.

View 2 Replies View RelatedI've recently installed openSuse 11.4 64bit with KDE 4.6 and that's when the trouble started. If I put a data or mp3 cd in the drive it can be mounted. Simple audio cds refuse to mount, giving me only the option to play on one of the audio players. Since I wanted to move some music to the computer I've had to resort to windows to copy files then transfer them. How can I force KDE/Suse to behave the way I want or do I have to revert to an earlier version with KDE3.5? I suspected that System Settings/Removable Devices was where I needed to be but nothing I did worked. So then I tried playing with System Settings/Device Actions and again nothing seemed to work. I can't mount the CD manually,I get this (using su -c "mount etc"
mount: block device /dev/sr0 is write-protected, mounting read-only

I have a monitoring program ( GIT link to sourceforge ) which I'm trying to use to track when a child exits/dies/whatever. I'm calling fork(), then close for 0,1,2, and then opening /dev/null, monitored.stdout, and monitored.stderr as a replacement. I'm not sure if I've done something incorrect (perhaps I should use dup2 for explicit assignment?) but it appears that printf() messages are just being blackholed. I've tried setting the line buffering as a last ditch effort. On a different system, using code similar to the spawn_monitor() function, this appears to work fine, which makes me think I'm relying on some implementation specific detail.
Relevant function, for those who don't click links:
Code:
26 int spawn_monitored(char *argv[])

View 1 Replies View RelatedBash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.

View 4 Replies View RelatedUp until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else
