How to remove unwanted output that comes from executing system api?
for eg:when i execute system("telnet 127.0.0.1") i want the output to start with login and then password and then directly the command prompt,how can i remove the output that gets generated before showing the prompt?
I'm using Ubuntu and I'm programing with eclipse CDT. My goal is to execute a php file and read the output to my c++ program. To do so I thought I should use fork(), dup2() and execl. When in shell, the call "php myscript.php" worked just fine, but when in c++ I tried:
execl("usr/bin/php", "php", "home/geiger/workspace/SemiServer/server_content/myscript.php", NULL);
And it didn't work (the process wasn't terminated and I got no output). I tried different version of this call, like losing the "php" string and/or drop "home/geiger" from the path string, to no better result.
I am writing a script which will fetch data from different machines and display it on single terminal. I have created a file named SERVERNAMES containing ip address of machines I need to monitor. Then for every IP I am issuing ssh command to get date on that machine. However When I am trying it on the script it is just giving me output of first server and it is ignoring rest servers mentioned in file. ssh works fine without password for all machines mentioned in SERVERNAMES.
Code:
# cat SERVERNAMES
10.180.45.231
10.180.45.235
10.180.45.238
10.180.45.211
Script
Code:
#!/bin/bash
while read line
do
#Calculate Load on remote machine.
Date=`ssh -T -q $line date`
echo "Date on $line is:$Date"
done < SERVERNAMES
Code:
output.
Date on 10.180.8.231 is:Wed Jul 14 10:48:46 IST 2010
I am not getting the output for .
Code:
10.180.45.235
10.180.45.238
10.180.45.211
Is there anything wrong in ssh?

I have a script, I am able to send the output of the script to both the screen and a file as shown below
Code:
./script | tee -a temp.log
I wonder is it possible to achieve same thing by executing some commands inside the script. As for other users, who execute the script it is not advisable to pipe the output of script with the help of tee command. Again, keeping |tee at the end of every line of the script doesn't seem to be advisable. I tried with this for couple of lines and it works. Is it possible to get the output of script to both screen and file by just executing name of the script, with some script tweaking ?

I have a WD external disk, NTFS file system. I mounted it on my Red Hat. While on the external disk, I deleted a directory, which was sent to .Trash-root of that disk.I went to .Trash-root and did rm -rf to completely delete that directory, but I got the following error: cannot remove `<directory>': Input/output errorWhen I do ls -la on that directory that I wish to remove, it shows me it has 0 files inside. But not only I can't remove it, I can't do anything else with it (copy, etc). And I have all the rights on that directory, so this isn't the problem.
View 6 Replies View RelatedUsing Nicotine+ I accidentally downloaded about 11000 files from an user who's evidently too busy to properly organize his archive, and got all his stuff stored in only one big folder.
Nicotine obviously crashed, and I'm not able to open it anymore. When I launch the program, it immediately freezes, and I can do nothing but force its quit. I tried to remove and reinstall the program, but the problem persists. So I was wondering if there's a way to remove the downloads from the list outside Nicotine, editing some files.
Ive managed to get myself in a bit of a hole through fears of destroying my WinXP on a new dual boot installation. I�ve been using Ubuntu (10.04 lts) alone on an old machine which died, so I thought I�d just move the hdd to my main machine & dual boot it with XP.
I booted from the 10.04 lts CD to set this up, I let it do as it suggested & assumed it would see the existing Ubuntu installation & modify it to dual boot with Win XP. Which it did except I now have two instances of 10.04 on the second hdd as it added a second partition for the new. Leaving the already installed 10.04 alone. I saw no options other than the advanced partitioning which I did not look at.
How please can I correct this & go back to having just one instance of 10.04 on the Ubuntu disk to dual boot to � I am sure there must be an easy way. I have nothing on the Ubuntu disk I need to preserve. I know nothing about Linux command line.
The default output audio port Ubuntu doesn't work on my system. It should be "Analog Mono Output/Amplifier", instead of "Analog Output/Amplifier". I can easily change that in sound preferences, just by choosing the right port in the "Output" tab. The problem is this would only apply to a single account, and I would like to change it system-wide, so it applies to all accounts on the system (I have more than 100 users...).
Update: I can achieve the same effect as I would by changing it in sound preferences using the following command: pacmd 'set-sink-port' 'alsa_output.pci-0000_00_1f.5.analog-stereo analog-output-mono;output-amplifier-on' Unfortunately that's still not system-wide,
Which commands do you use to output the current users logged into the system and accessing a specific file?

If you create a file on UNIX/linux with special chars, like touch "la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the before the name, I know, but you'd have to guess as a user that it was used in the file creation).
I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either.
What is the command for this?

I'm confused while trying to fix controls styles (tabs, buttons, scrollbars, main menus, popup menus) of my 3dparty applications in KDE. The problem reflected in the fact that all controls of non-KDE applications (Firefox, Zend Studio, Gimp,..) have Gnome styles. But setted widget style is "Oxygen".I assume that this problem has appeared after installing new fonts in my system.

I got rid of Windows_recover partition (I don't remember the exact name) converted that primary partition to an extended partition and then installed Ubuntu in virtual partitions. All that works.What I don't like is that the partition HP_TOOLS shows up in Nautilus, and if you click on it, it self-mounts and makes that partition accessible.

When running rsnapshot tonight it failed with a bunch of

I got a new HDD like a Storage on my Ubuntu ,it is formated as ext3 and i am able to mount it ,but sometimes while downloading from FTP ,when the session broke Ubuntu crates some ./afternature.mp4 Input/output error ,which i can see on "ls -l" ,and that causes great troubles to me ,because i can not copy or write on that disk another file with the same one which is created like this ,these error are gone only if i format the hdd .
My mounting command is "mount /dev/hdb3 /tmp/hd ext3 rw 0 0" So is that possible to remove these error without formatting the disk . PS:I did a lot of search for that error ,on unix forums also here but i didn`t find a concrete answer ,i found a thread which is for that case but removing with inode is impossible because on ls -l i`m not receiving the inode .
