General :: Create A File In The Current Directory Named '5' With The Number '2'?
Aug 24, 2010
Code:
$ echo 2 * 3 > 5 is a valid inequality. This will create a file in the current directory named '5' with the number '2' in it, the names of all the files in the current directory, followed by the number '3' and 'is a valid inequality.'
What I do not understand is why 'is a valid inequality' gets written to this file. I thought it would write '2', all the file names in the current directory, then '3' into the file called '5'. Why does the 'is a valid inequality.' get written to the file also?
What command will provide you with the number of files in your current directory? Choose one answer. A. ls -c B. ls | wc -w (this one) C. ls -n | count D. ls -wc (this one ?)
Mandriva 2009, BIND 9.5.0-P2. Named will start however I'm getting the above error as well as these:
14-Mar-2009 15:45:37.084 general: error: zone 0.in-addr.arpa/IN: loading from master file /var/lib/named/var/named/reverse/named.zero failed: file not found 14-Mar-2009 15:45:37.084 general: error: zone 0.0.127.in-addr.arpa/IN: loading from master file /var/lib/named/var/named/reverse/named.local failed: file not found
[code].....
Named shows to be running but with the errors above I know it's not running correctly. I also copied the above dir's over to /var/lib/named/var/lib/named which is where I 'believe' it's chroot'd at, though I could be wrong since I'm unfamiliar with chroot.
I have several directories of subtitles for some videos, but all the text for the subtitles in each file is in uppercase, and I would like to convert the files' content to lowercase, all in one go. I found on a website a bash command that would do each file separately:tr '[:upper:]' '[:lower:]' <input.txt> output.txt but of course involves specifying the input name and output name for each file.I have been trying to do it in a script that would work for all files in the current directory, without having to rename them each time, if that's possible. So far I've got the following, which doesn't work:
#!/bin/bash for file in $@; do tr '[:upper:]' '[:lower:]' done
However, my web searches cannot locate a way of specifying "each file in current directory" in conjunction with the "tr" command, but also without having to rename the file once converted to lowercase. Is it possible, or would the tr command have to create a new file for each converted file?
I'm trying to compile a program from source. When I run make the following appears:./ config. status --recheck make: ./config.status: Command not found make: *** [config.status] Error 127.There is no file called config. status in the current directory. Why was it not created?
I am total new to linux as I worked mostly on RTOS (symbian). My problem is, I need to find the file IOSTREAM.H and I am following commands below: 1) cd / 2) find . iostream.h ( finds the file / directory from the current path) It shows No such File or Directory

My question deals with me creating a name pipe (file) in the my /group directory called chat.I then have to write a script to read from the named pipe and save data into a file called chat.log until the words End of File are passed to the program.
-When I created the named pipe file (chat) I used the mknod chat p command..Is this the correct command to create a named pipe file? -Then I'm having trouble with my script and how to make it run until the words End of File are entered in. This is what I have so far.

I am trying to create hard links within a file system to a directory, but unable to do that. is there any limitation to create hard links to directories within file system ?
I would like to create a directory public_html/archive that is a mirror of public_html/images, except that deletions in the images directory don't cause corresponding deletions in archive.
I was going to manage all of this in code, but then I figured, maybe the system can handle it for me in a robust way.
Note that the website will reference archive in real time, so it has to be an instant mirror and not something done nightly, etc.

What does this code do, why, and what's causing it to go wrong?
i'm just trying to understand named pipes in linux.For that i'm just trying to create one named pipe using mkfifo.but its not working properly..following is my code snippet. so if anyone comes across the mistake i made
I'm working with a dual-boot laptop running Ubuntu 10.0/Windows 7 and a Debian 5 VPS while the OS's shouldn't have much impact on my question.
What I would like to do is create a html page that I can upload to my VPS which lists all of the files/folders on my local 2TB hard drive (Specifically media such as Movies, Music, TV Shows...). The media obviously will not reside on the server, but I would like to at least have a list which will allow me to select, for instance, a bands artist so that it redirects me to the albums in the directory below.
Ultimately, I'm looking for Open Directory Browsing without actually having the media on my server. I have been attempting to create something to this effect using lynx, however, I'm not sure if it can be done with this command or if it's even possible for that matter.
I am in my current directory. I want to copy a directory somewhere else into this current directory. Lets say I want to take it from direc1/direc2 and the directory I want to take is called demo.
Code:
That is what it shows in the man pages, but when I do that, it says cp: no match
I need to create a script to count the number of lines from a text file . The output must be put on another text file (no_lines.txt) and in this file i need to generate from the script this output :"File $FILE has $NO_LINES lines ".
I need to write a script that is given a directory as an argument, and it prints the last modified file from that directory and all its subdirectories.
for example:
$ newest /usr/etc --> /usr/etc/httpd/httpd May 28 12:16
If I had to do it only for the current dir, it would be easy...I'd probably use "ls -lt" and then show only the first line...
### TO DO: Determine the report file name based on the source directory name and current date### The report name and thumbnail directory must follow this pattern: source-%j-%H### for example, for pictures in /home/you/pictures, the file name will be: pictures-%j-%H### HINT: Use sed to extract the directory name from the path and combine it with date command output
Is there any program/script that can create a torrent file for each file in a directory? I have been looking all over but can't seem to find anything of the sort. I have 700+ files I REALLY don't want to make my self.
I have iMac 2.4GHz with rEFIT installed. I installed Unity on one of the partition. Kernel is still 2.6.38.8. I am getting error message when I run the command sudo gedit /etc/x11/xorg.conf

Well, I am facing problem when doing lab questions.
I must use DLXLinux bundled in Bochs (bochs.sourceforge.net).
I am required to use the /usr/local directory.
In /usr directory, there is no directory named 'local' but there is one thing called 'local@'. So, when I try to use mkdir command to create 'local' directory in /usr , there are error "cannot make directory.....".
i need to know how to find number of files in a directory? is there any system calls in fedora 12.And i need to know how to perform a operation if the that count increases by one?
