wget interview questions
Top wget frequently asked interview questions
I am trying to download the files for a project using wget as the SVN server for that project isn't running anymore and I am only able to access the files thorugh browser.
The base URLs for all the files is the same like -
http://abc.tamu.edu/projects/tzivi/repository/revisions/2/raw/tzivi/*
How can I use wget or any other tool to download all the files in this repository where the "tzivi" folder is the root-folder and there are several files and sub-folders(upto 2 or 3 levels) under it.

I'm using Wget to make http requests to a fresh web server. I am doing this to warm the MySQL cache. I do not want to save the files after they are served.
wget -nv -do-not-save-file $url
Can I do something like -do-not-save-file
with wget?

Are they the same or not? Can certain things be done with one but not the other? What are those? Or is it, at the end of the day, a matter of familiarity?

When I try to download Java from Oracle I instead end up downloading a page telling me that I need agree to the OTN license terms.
Sorry!
In order to download products from Oracle Technology Network you must agree to the OTN license terms.
Be sure that...
- Your browser has "cookies" and JavaScript enabled.
- You clicked on "Accept License" for the product you wish to download.
- You attempt the download within 30 minutes of accepting the license.

I have a web directory where I store some config files. I'd like to use wget to pull those files down and maintain their current structure. For instance, the remote directory looks like:
http://mysite.com/configs/.vim/
.vim holds multiple files and directories. I want to replicate that on the client using wget. Can't seem to find the right combo of wget flags to get this done. Any ideas?

I need files to be downloaded to /tmp/cron_test/. My wget code is

I am downloading a file using the wget
command. But when it downloads to my local machine, I want it to be saved as a different filename.
For example: I am downloading a file from www.examplesite.com/textfile.txt
I want to use wget
to save the file textfile.txt
on my local directory as newfile.txt
. I am using the wget
command as follows:
wget www.examplesite.com/textfile.txt

I would like to download a local copy of a web page and get all of the css, images, javascript, etc.
In previous discussions (e.g. here and here, both of which are more than two years old), two suggestions are generally put forward: wget -p
and httrack. However, these suggestions both fail. I would very much appreciate help with using either of these tools to accomplish the task; alternatives are also lovely.
Option 1: wget -p
wget -p
successfully downloads all of the web page's prerequisites (css, images, js). However, when I load the local copy in a web browser, the page is unable to load the prerequisites because the paths to those prerequisites haven't been modified from the version on the web.
For example:
- In the page's html,
<link rel="stylesheet rel='nofollow' href="/stylesheets/foo.css" />
will need to be corrected to point to the new relative path of foo.css
- In the css file,
background-image: url(/images/bar.png)
will similarly need to be adjusted.
Is there a way to modify wget -p
so that the paths are correct?
Option 2: htttrack
httrack
seems like a great tool for mirroring entire websites, but it's unclear to me how to use it to create a local copy of a single page. There is a great deal of discussion in the httrack forums about this topic (e.g. here) but no one seems to have a bullet-proof solution.
Option 3: another tool?
Some people have suggested paid tools, but I just can't believe there isn't a free solution out there.
Thanks so much!

I'm trying to wget
to my own box, and it can't be an internal address in the wget (so says another developer).
When I wget, I get this:
wget http://example.com
--2013-03-01 15:03:30-- http://example.com/
Resolving example.com... 172.20.0.224

OpenSSL: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
Unable to establish SSL connection.
I believe it is because I do not have the certificate setup properly. Using openssl:
openssl s_client -connect example.com:443
CONNECTED(00000003)
15586:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:588:
While if I do the same command on another site, it shows the entire cert.
Perhaps the ssl cert was never setup in the conf file on Apache for that domain?
If so, what should I be specifying in the virtualhost? Is there any alternative other than specifying --no-certificate-check
because I don't want to do that?

This question already has an answer here:
I'm new to Objective-C and I want to download a file from the web (if it was changed on the webserver) and save it locally so it can be used by my application.
Mainly I want to implement what wget --timestamp <url>
does.
