Option -O (upper-case O) is important. Without this, curl will start dumping the downloaded file on the stdout. Using -O, it downloads the files in the same name as the remote server. In the above example, we are downloading strx25-0.9.2.1.tar.bz2, so the downloaded file will also be the same name.
Updated 2017-08-01 to fix typo and use new demo URL. Also note that the Homebrew package manager has matured since this post was first published in 2012. Once you’ve configured Homebrew, installing a tool like wget is as simple as running
wget is an incredibly useful GNU tool on Linux. Unfortunately, it doesn’t come with OS X (as of Mountain Lion). OS X includes curl, which is a very handy tool but lacks at least one important feature of wget: the ability to use wildcards to get multiple files at the same time. For example, let’s say you want to download a subset of files from an FTP server. With wget, you could type:
brew install wget

Here is how to mimic that process with curl and a few UNIX command-line tricks.
1. Download the directory listing and save it in a file.

- If you set up a queue of files to download in an input file and you leave your computer running to download the files, the input file may become stuck while you're away and retry to download the content. You can specify the number of retries using the following switch.
- Wget: Simple Command to make CURL request and download remote files to our local machine.-execute='robots = off': This will ignore robots.txt file while crawling through pages. It is helpful if you're not getting all of the files.-mirror: This option will basically mirror the directory structure for the given URL.
- Note that the download file save as option inheriting file name is particularly useful when using URL globbing, which is covered in the bash curl loop section. Now let’s move on to how to check headers prior to downloading a file with curl in bash.
- Curl is another effective download tool, it can be use to upload or download file with giving a simple command, it supports pause or resume of downloaded package and supports maximum of web protocols, it can predict time left in download to be complete, progress is visible via progress bar.
2. Use grep with regular expressions to parse the .html file, extract the .igs file names and save them in a text file.

3. Use a bash loop to iterate over the text file and fetch each file with curl.

Another advantage of the curl approach is that wget doesn’t support wildcard characters with HTTP URLs (only FTP).
