Linux download every link in file

Curl is another command line tool that can be used to download files from the internet. Unlike Wget, which is command line only, features of Curl are powered by libcurl which is a cross-platform URL transfer library. Curl not only allows downloading of files but can also be used for uploading and exchanging of requests with servers. However, Curl does not support recursive downloads which Wget offers. Similarly, like Wget, Curl comes pre-installed with most of the Linux Distributions.

This can simply be checked by running the following command:. Just like Wget, Curl has multiple features incorporated inside of it. The most basic is its ability to allow users to download files from a single URL from the internet. For better understanding, we will be downloading a simple image in the png format from the internet just like in the case of Wget. Curl also allows users to change the filename and the type of the file.

This can be done by the following command:. In the image above, we took a png file originally named pancake1. Just like in the case of Wget, Curl allows users to download multiple files using a number of URLs from the internet. For our example, we will use curl to download a jpg file and a png file from the internet. Results are shown in the image below:. A pretty amazing feature that Curl provides to its users is its ability to monitor the progress of the download of the file.

For more information regarding Curl, users can input the following command into the terminal to get access to all the Curl commands that appear to be available:. Wget and Curl are among the wide range of command line tools that Linux offers for the downloading of files. First, let's delete the link main. Remember that every directory entry that points to an inode is simply a hard link.

The link main. Deleting it now still leaves the original file and its data on the hard drive along with all the remaining hard links.

To delete the file and its data, you would have to delete all the remaining hard links. Notice what happens to the soft link. Deleting the hard link to which the soft link points leaves a broken link. On my system, the broken link is highlighted in colors and the target hard link is flashing. If the broken link needs to be fixed, you can create another hard link in the same directory with the same name as the old one, so long as not all the hard links have been deleted.

You could also recreate the link itself, with the link maintaining the same name but pointing to one of the remaining hard links.

Of course, if the soft link is no longer needed, it can be deleted with the rm command. The unlink command can also be used to delete files and links. It is very simple and has no options, as the rm command does. It does, however, more accurately reflect the underlying process of deletion, in that it removes the link—the directory entry—to the file being deleted.

I worked with both types of links for a long time before I began to understand their capabilities and idiosyncrasies. It took writing a lab project for a Linux class I taught to fully appreciate how links work.

This article is a simplification of what I taught in that class, and I hope it speeds your learning curve. If you use an editor which makes automatic backups - emacs certainly is one such - then you may end up with a new version of the edited file, while the backup is the linked copy, because the editor simply renames the file to the backup name with emacs, test. Why are there always a large number of empty device files? Would it be possible for the hardware to be interrogated on startup and just files corresponding to the actual hardware be generated?

Thanks for any answers. The short answer is yes, Linux has been doing just as you suggest for quite some time, now.

I am sure it seems that there are many more device files than actual devices, but most are actually used in one way or another.
