I am not really a Linux or unix user, so apologies if the question seems too easy to be asked on the forum, but I tried using the search engines and failed.
Code:
cat < foo 2> bar
Why doesn't this get redirected to stderror on error conditions?
I execute an application from a script file and redirect stdin to it from here-doc like this:
my_cli << HERE_DOC
enable
configure
10
exit
exit
HERE_DOC
This works as expected, but I don't see neither the input nor the app output. The application is an interactive prompt written in C. When I interact manually with it, I see the prompt itself and responses to my input, but when I execute the aforementioned script I see nothing. I would like it to print the input and the output as if a real user was typing. Do you know how to achieve that?
If I do the following, if the URL is a redirect, it doesn't work
rpm -ivh http://path/to/rpm
I have to use wget http://path/to/rpm which resolves the redirect and downloads the file, then run rpm on that file.
More for my knowledge of bash than anything else, would there be a way to redirect the file downloaded from wget into the rpm (something like redirection or pipes or something), so that they could be combined into one command and you wouldn't explicitly save the file first.
Something like... rpm -ivh << wget http://path/to/rpm
I have one more question, and that is whether there is a command in linux, such as wget, that would let me pass it a URL and output the redirected-to URL if the argument.
e.g. ('wget --someflag http://orig/url' would output 'http://url-after-redirects-followed')
I was unable to find an answer to something that (I think) should be simple:
If you go here: [URL]
like so:
wget [URL]
you'll probably end up with a file called "download_script.php?src_id=9750"
But I want it to be called "molokai.vim", which is what would happen if I used a browser to download this file.
Question: what options do I need to specify for wget for the desired effect?
I'd also be ok with a curl command.
This happens at random and the problem persists even when using an alternative browser (Firefox & Chrome), being redirected to the same website. Sometimes it's [URL] going to [URL] going to AOL Lifestream.
View 4 Replies View RelatedSo, I just installed Fedora yesterday. I have been trying out different Linux distros and Fedora was next after Ubuntu and SuSE failed severely. So, I installed F14 yesterday and everything has been great... until I tried to set my JAVA_HOME variable. I followed the instructions here.
After editing $ vi ~/.bash_profile as the site instructs, I proceeded to log-out and log back in...except I can't log back in. I have repeatedly gotten the login screen, selected my account, and entered my password. When I enter my password incorrectly, it says 'Validation Error' and that is not what is occurring. The display goes black for a couple of seconds and I am redirected back to the log in screen.
I have remote server and when I want to connect to it from internet I need to choose port 2222. I tryed to do it using filezilla, gftp, it can be done. Because they want from me to use default ssh port 22

it never really prints out to the file.
It worked earlier, but I was playing with my PATH lately, I don't know if it's related to that

I've been switching out computers to the Ubuntu distro and so far it's been very successful until this recent snag! As I am trying to have a printer plugged in through USB on one computer and shared on the other! I have the USB on the second computer and it found the printer just fine, no problems and nothing else I had to install! I then went to the first computer and tried to add the printer through the CUPS website using all the proper addresses and queue names and I receive CUPS "client-error-not-possible". I have read other threads on this very same problem but to be honest they just make no sense whatsoever to me! I was thinking of just giving up and using a print server but I know that I will run into the same snag as even then I still need CUPS.

Ubuntu 9.10 was set up to handle the booting selection - previously I thought it was xp but Ubuntu 9.10 "did" it. The system started out as a xp / ubuntu 9.10 dual boot on a 400gb drive. xp has 210gb, ub has 80 and their is a 100gb shared storage. Xp was installed first and then I followed a guide over at linuxconfig.org to get ub installed so that I could select which OS was wanted at boot. Ubuntu manages the boot up menu (Went back to look at my notes from the original setup) The owner tried to update to ub 11.04 and afterall was said and done the machine now boots to the message
error file not found grub rescue I can't say if 11.04 was properly installed or not. Ask whatever you like and I'll give the best answer I can. I think the xp install is okay but I can't say for certain as I don't know how to boot it outside the bootmanager at startup. Data has been saved so if I have to blow it all away and start over I can but I'm hoping I won't have to.

I've been using Kate for a while without any problems.
However, today I tried to install Kedit.
Then I got this message:
"There was an error setting up inter-process communications for KDE. The message returned by the system was:
Could not read network connection list. /home/mikeb/.DCOPserver_XXX__0
Please check that the "dcopserver" program is running!"
Then I uninstalled Kedit, hoping that the damage would be undone.
However, Kate still shows the same message upon startup.
So I reinstalled Kate, and got the same thing.
What did the Kedit installation mess up, and how I can I fix it so I can use Kate again?
GNU Emacs 23.1.1 I've noticed that if I run Emacs and M-x server-start, I can use the emacsclient program as usual, but if if I start Emacs using emacs --daemon and then try to use emacsclient the new frame locks up and the shell outputs *ERROR*: Arithmetic error. This issue doesn't happen if I use the -t flag to force terminal mode when running emacsclient.
