General :: Stuck On Join Command From Book?
Feb 10, 2011
Going through book, "Guide to UNIX Using Linux". I am doing one of the projects that has me writing scripts to join files. Here is my pnumname script and I am extracting the programmers names and numbers from the program file and redirecting the output to the file pnn. I then created a joinall script where I am trying to join the files pnn and pnumname and redirect the output to pactrep. When I run the script sh joinall and use less to display the contents of the redirected file pactrep, I get an error- join: extra operand `pnum'
Try `join --help' for more information.... I went to the man pages but I still (obvious) do not have a solid grasp.
#=======================================================
# Script Name: pnumname

I am trying to understand the join command. I wish to join two files:
Code:
$ cat test1
a 0
b 2.51
c 19.85
$ cat test2
a 0
b 2.51
[Code]...
this is great but I do not understand why join ignores the -e flag and fails to insert FOO in the empty field.

I am running Natty Alpha 3. I used Update Manager to install something (not sure what it was), then I restarted, but instead of listing all the kernels, it gave me a command line. I don't know what happened and how to use it.

Am a bit bewildered on the output of this "join" comad. I'm expecting it to output the 2nd and 3rd columns of both text1.txt and text2.txt. However, it somehow misses some of the columns from text1.txt. For example, rows 1, 2, 8, and 14 are working as expected. The rest of the row aren't.
Code:
cat text1.txt

I was deleting some space off my C Drive and I believe I may of accidentally deleted Fedora, or some of it! I have a dual boot with Fedora and Windows XP so when I started my desktop up it would load into fedora by default or I could press a key to load XP! (It rhymes!) Now, however, it instantly loads up into "Grub"
And that's it! Run, Or Exit, or anything really, doesn't work! Except Reboot! So I'm a little stuck. It's an old PC and the Windows XP disc is long gone, if I ever had one! I had this thought that perhaps if I reinstall Fedora from a CD it many bring back the old command prompt and let me get back into XP again? Or, is that crazy talk??

I just loaded up the Ubuntu 10.04 onto a newly scratch built computer. It went to the desktop after loading up and asking for my password. I then navigated to SYS>ADMIN>DRIVERS and preceded with download of recommended drivers for Nvadia G430 on-board display adapter. Restarted the computer to activate the new drivers and it's stuck in Command Line Mode. I tried Ctrl/Alt/F7 to escape, along with a bunch of other things but nothing will kick this puppy into the desktop.

I am using 11.3 on one machine and 11.2 on the other (a netbook). 11.4 won't install on either and 11.3 on the netbook fails to install as well.
I am using the same setup as I have always used when both systems ran 11.2 (details below) but now I can only mount a drive in one direction. In the other direction the mount command gets stuck with no error message until it eventually times out. I can ping and ssh the machines from each other without difficulty.
Even in the direction in which the mount apparently works (11.2 mounting a drive on the 11.3 machine) when I try to copy files across nothing actually happens.
exportfs -a was run successfully on the exporting machine, and nfsserver is running on both machines as does nfs client.
The exporting machine is 192.168.1.102 (eeelinux) and the other machine is 192.168.1.101 (nina).
Details:
The /etc/exports file on the exporting machine (192.168.1.102) looks like this:
eeelinux:/home/naima # more /etc/exports
# See the exports(5) manpage for a description of the syntax of this file.
# This file contains a list of all directories that are to be exported to
# other computers via NFS (Network File System).

Last night my system rebooted and dropped screen resolution to 800*600. I was unable to change that from no where. I tried to install nvidia driver and now no gui, only command line. Starting xorg by using 'startx' fails. How I can get back to normal with normal resolution?At the moment I am logged in via live cd. Let me know if any log files needed (if I can locate those).

I want to use the command line join utility on two files. Unfortunately, they're gzipped. Because they're both gzipped, I can't use gzip -cd. Is there a slick way to do this without having to unzip them?

Searching Google on how to join/merge many mp3 files, it suggests that I should just cat them together.That might "work", but clearly it is not the correct way to do it, as each header and set of IDv3 tags will also be concatenated.Does a Linux program exist that can be scripted to join/merge many mp3?Can mplayer/mencoder/ffmpeg do it?

How do you join multiple MP3 files into one? "cat" and "mp3wrap" are no good as they produce non standard MP3 files. I know I can use audacity, but when you have 1000's of MP3 files to join into one, it takes too long.

I have $db and $DATE set in my bash script, then I need to join them like this: mysqldump --user=usr --password=pss --databases $db | gzip > /backups/sqlNew/$db_$DATE.sql.gz;
Unfortunately, that doesn't work. How do I properly join those 2 variables into a filename?

Is it possible to add/join my Linux Suse 11.3 server with 2 domains ? I know I can do that with Windows PC, but I never try that with my Linux box. FYI, my Linux server is already joined with a domain, now I want to join my box with another domain and I don't want to take it off the current joined domain.

We've been running samba on linux for a while and everything was fine. All of a sudden when you add new clients to the domain you get the error message :Logon Failure:unknown user name or bad password. This to me seems like a windows error message and not a samba error. When you remove an existing machine (ie on domain) and then try to rejoin it to the domain you fail.

I have many years of experience with DOS and Windows, but this is my first dabble in Linux, in particular Fedora 13. The OS is great, but my lack of knowledge makes me uneasy. Is there a good book available in HTML or PDF format that covers. The basics, and is relevant to Fedora 13?

I wanted to install this package to convert one Unix book into pdf. Since I have not set up the internet in the debian, I download the .deb files in winxp and transfer these files to my pen drive and then access it in the Debian. So I got all the 'depends' packages for the chm2pdf from the Debian Packages site and tried to install. Console was still asking for more dependencies. If I have got all the 'depends' packages which are required for chm2pdf, then why does it give problems ?

What would be a good book/manual to read to learn more about linux o.p. systems? and how to use them.I have to add I may not have such a good internet connection I might end up with free dial up (Bummer)so I'm not sure if a link will do.I will end up at the library anyway. so if you could suggest something that would be good, I'm not really looking for the history but more like how to use, maybe the terminal and such?.
