I have set up a cron job in linux server using the command 'wget -q -o wget_outputlog url'
But on every run, an empty file being created at root.
How to stop this.
Debugging some of my scripts after upgrading from Debian Lenny to Ubuntu 10.04. In so doing, I tripped over this "problem," the solution to which may give me a clue to others.
On a bash shell command line I created a file thusly:
sudo touch zero_file
and it lists as expected with default permissions 0644:
-rw-r--r-- 1 root root 0 2011-03-09 11:18 zero_file
But then this command fails
sudo echo abcdef >>zero_file
-bash: zero_file: Permission denied
I can place the command (minus the "sudo") in a script & run it under the auspices of sudo & it works. Am I missing something re the stdin redirection when using sudo?
I get a page of rssfeed.php in my root dir, whenever i run it once more, there goes a new rssfeed.php.0, rssfeed. php.1...etc, the number increases. but all of them stays empty, is there a tag that avoids this?I am not sure which one to use on the man page, there is -o for output, but none for no output?
View 1 Replies View RelatedI have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.

I scan a document with root pressing the scanner button. I would like to send an email using my gmail account. OK. nothing difficult with that... mbsmtp + mutt for sending trhough the sh script.
1-root is to be avoided at max to do some internet duties, due to security. Apt-get is good, but ok surfing or email sending shall be avoided for higher security.
2- sudo or su running mutt through this way, ok, using an existing user. OK, possible and simple, but not comfortable since you have to use an account of an user existing (create a new user for scanner and email?? - no, come on, we have linux and can maybe find a solution)

when i wget aro2220.com it displays

However, when I look into the file it is actually blank saying something like "It works! This is the default web page for this server" which can't be correct since that is not what Aro2220.com actually displays.
Furthermore, when I try to wget files I've put on the server for myself it returns a 404, file not found.
I would like to use wget to downlaod file from Redhat linux to my windows desktop , I tried some parameter but still not work , can advise if wget can do download file from linux server to windows desktop ? if yes , can advise how to do it ?

View 7 Replies View RelatedI 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.
Example: [url]
This was what I tried...wget -A rar [-r [-l 1]] <mediafireurl>
That is to say, I tried with and without the recursive option. It ends up downloading an HTML page of a few KB in size, while what I want is in the range 90-100 MB and RAR.
What happens with MediaFire for those who may not be aware, is that it first says

This text after a second or so turns into the download link and reads
Click here to start download..
How to write a proper script for this situation.
how can I define file type for wget to download . for example I do not want to download *.html or I just want to download *.jpg files . or if it does not support any of them do you know any other suggestion ?

I have just recently installed Fedora 14 Standard Edition. Upon after mounting another parition, I attpempt to find the new partition files in the directory I created for the mount point, but it is not showing. I know the mounted parition is there becuase upon "ls -l /iso", all the files show up.
I had previously tried out Fedora 14, XFE, and this problem did not occur. I also previously installed this same Standard Edition, and this problem did not occur. This is from the exact same download, however, the only difference is I installed Grub into a different partition. But now I am unable to find my new folders in Gnome.
I have a large file that a process writes to. I would like to empty that file. If I delete it the process will stop writing to it. Just flush the content but keep the file.
View 9 Replies View RelatedI need to use wget (or curl or aget etc) to download a file to two different download destinations by downloading it in two halves:
First: 0 to 490000 bytes of file
Second: 490001 to 1000000 bytes of file.
I will be downloading this to separate download destinations and will merge them back to speed up the download. The file is really large and my ISP is really slow, so I need to get help from friends to download this in parts (actually in multiple parts)
The question below is similar but not the same as my need: How to download parts of same file from different sources with curl/wget?
aget
aget seems to download in parts but I have no way of controlling precisely which part (either in percentage or in bytes) that I wish to download.
Extra Info
Just to be clear I do not wish to download from multiple locations, I want to download to multiple locations. I also do not want to download multiple files (it is just a single file). I want to download parts of the same file, and I want to specify the parts that I need to download.
I have this nasty habit of refreshing desktop in a quick succession by right-clicking and selecting 'Refresh',on my XP system at office.(And,iam sure most of us do the same).With Ubuntu,if a right-click on desktop slowly and select 'align by...',it simulates the XP refresh action as explained above.But,if i perform the same action rapidly,it takes this first option from right-click context menu,which is 'Create Folder',and results in an empty folder being created on desktop.I tried double right-clicking and again it created an empty folder.Is there any workaround to handle this.I mean:Can the right-click context menu items be shuffled so that the 'Create Folder' option is moved from 1st place

a) The process ended with a 88GB file size (which is ok) but with the following message.Code: tar: Exiting with failure status due to previous errors.I have searched a little but I could not find what went wrong.
b) What are the limitations of tar and gz for backups. Of course I fully understand that they can not be used for differential backups (if it is called like that)
c) Let's say that my backup will be a file of 100GB and I want to see the contents of the .tar.gz. In kde there is a program called ark. Can ark handle so big files? Does it use my hard disk (eg. /tmp) to uncompress the file so to show me its contents? It might be the case that might be the compressed file is much bigger than the left space on the hard disk?
d) How can I do an integrity check when my tar.gz file is created?
