    wget vs curl: How to Download Files Using wget and curl

    posted in weboga on 8th Mar, 2017

    Question: I typically use wget to download files. On some systems, wget is not installed and only curl is available. Can you explain me with a simple example on how I can download a remote file using curl? Are there any difference between curl and wget?

    Answer: On a high-level, both wget and curl are command line utilities that do the same thing.

    • They both can be used to download files using FTP and HTTP(s).
    • You can also send HTTP POST request using curl and wget
    • However curl provides APIs that can be used by programmers inside their own code. curl uses libcurl which is a cross-platform library.
    • wget is just a command-line tool without any APIs.
    • Curl also supports lot more protocols that wget doesn’t support. For example: SCP, SFTP, TFTP, TELNET, LDAP(S), FILE, POP3, IMAP, SMTP, RTMP and RTSP.
    • There is a major advantage of using wget. wget supports recursive download, while curl doesn’t.

    Wget Examples

    The following example downloads the file and stores in the same name as the remote server.

    wget http://www.openss7.org/repos/tarballs/strx25-0.9.2.1.tar.bz2

    The following example download the file and stores in a different name than the remote server. This is helpful when the remote URL doesn’t contain the file name in the url as shown in the example below.

    wget -O taglist.zip http://www.vim.org/scripts/download_script.php?src_id=7701

    Curl Examples

    $ curl -O http://www.openss7.org/repos/tarballs/strx25-0.9.2.1.tar.bz2
      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                     Dload  Upload   Total   Spent    Left  Speed
     28 3762k   28 1085k    0     0  72771      0  0:00:52  0:00:15  0:00:37 54267

    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.

    Instead of -O, you an also specify, “–remote-name” as shown below. Both are the same.

     
    $ curl --remote-name http://www.openss7.org/repos/tarballs/strx25-0.9.2.1.tar.bz2

    While curl is downloading it gives the following useful information:

    • % – The total % of the download that was completed as of now. When it gets to 100% the download is completed. In the above example, it has downloaded only 28% of the file.
    • Total – The total size of the file
    • Received – The total size of the file that was has been downloaded so far. In the above example, it has downloaded 1085k so far (out of 3762k total)
    • Xferd – This will be used when you upload some files to the remote server. During upload, this will indicate the total size of the file that has been uploaded so far. Since we are downloading a file, in this example, this is 0.
    • Average Speed Dload – This indicates the average download speed.
    • AVerage Speed Upload – While uploading a file, this will indicate the average upload speed
    • Time Total – This indicates the total time it will take to download (or upload) the whole file based on the current download (or upload) speed. In this example, it will take approximately a total of 52 seconds to download this file.
    • Time Spend – The time curl has spent so far downloading (or uploading) the file. In this example, it has spent 15 seconds so far.
    • Time Left – This is caculated based on “Time Total” – “Time Spent”.
    • Current Speed – This indicates the current download/upload speed. Compare this with Average Spped Dload/UPload to see how fast or slow your system is downloading currently.

    If you want to download the file and store it in a different name than the name of the file in the remote server, use -o (lower-case o) as shown below. This is helpful when the remote URL doesn’t contain the file name in the url as shown in the example below.

    $  curl -o taglist.zip http://www.vim.org/scripts/download_script.php?src_id=7701
      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                     Dload  Upload   Total   Spent    Left  Speed
    100 50243  100 50243    0     0   170k      0 --:--:-- --:--:-- --:--:--  400k

    In the above example, there is no file name in the remote URL, it just calls a php script that passes some parameter to it. However, the file will be downloaded and saved as taglist.zip on your local system. Instead of -o, you an also specify, “–output”.

    Get Composer

    posted in php on 8th Mar, 2017

    Introduction#

    Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

    Dependency management#

    Composer is not a package manager in the same sense as Yum or Apt are. Yes, it deals with "packages" or libraries, but it manages them on a per-project basis, installing them in a directory (e.g. vendor) inside your project. By default it does not install anything globally. Thus, it is a dependency manager. It does however support a "global" project for convenience via the global command.

    This idea is not new and Composer is strongly inspired by node's npm and ruby's bundler.

    Suppose:

    1. You have a project that depends on a number of libraries.
    2. Some of those libraries depend on other libraries.

    Composer:

    1. Enables you to declare the libraries you depend on.
    2. Finds out which versions of which packages can and need to be installed, and installs them (meaning it downloads them into your project).

    See the Basic usage chapter for more details on declaring dependencies.

    System Requirements#

    Composer requires PHP 5.3.2+ to run. A few sensitive php settings and compile flags are also required, but when using the installer you will be warned about any incompatibilities.

    To install packages from sources instead of simple zip archives, you will need git, svn, fossil or hg depending on how the package is version-controlled.

    Composer is multi-platform and we strive to make it run equally well on Windows, Linux and OSX.

    Installation - Linux / Unix / OSX#

    Downloading the Composer Executable#

    Composer offers a convenient installer that you can execute directly from the commandline. Feel free to download this file or review it on GitHub if you wish to know more about the inner workings of the installer. The source is plain PHP.

    There are in short, two ways to install Composer. Locally as part of your project, or globally as a system wide executable.

    Locally#

    Installing Composer locally is a matter of just running the installer in your project directory. See the Download page for instructions.

    The installer will just check a few PHP settings and then download composer.phar to your working directory. This file is the Composer binary. It is a PHAR (PHP archive), which is an archive format for PHP which can be run on the command line, amongst other things.

    Now just run php composer.phar in order to run Composer.

    You can install Composer to a specific directory by using the --install-dir option and additionally (re)name it as well using the --filename option. When running the installer when following the Download page instructions add the following parameters:

    php composer-setup.php --install-dir=bin --filename=composer

    Now just run php bin/composer in order to run Composer.

    Globally#

    You can place the Composer PHAR anywhere you wish. If you put it in a directory that is part of your PATH, you can access it globally. On unixy systems you can even make it executable and invoke it without directly using the php interpreter.

    After running the installer following the Download page instructions you can run this to move composer.phar to a directory that is in your path:

    mv composer.phar /usr/local/bin/composer

    Note: If the above fails due to permissions, you may need to run it again with sudo.

    Note: On some versions of OSX the /usr directory does not exist by default. If you receive the error "/usr/local/bin/composer: No such file or directory" then you must create the directory manually before proceeding: mkdir -p /usr/local/bin.

    Note: For information on changing your PATH, please read the Wikipedia article and/or use Google.

    Now just run composer in order to run Composer instead of php composer.phar.

    Installation - Windows#

    Using the Installer#

    This is the easiest way to get Composer set up on your machine.

    Download and run Composer-Setup.exe. It will install the latest Composer version and set up your PATH so that you can just call composer from any directory in your command line.

    Note: Close your current terminal. Test usage with a new terminal: This is important since the PATH only gets loaded when the terminal starts.

    Manual Installation#

    Change to a directory on your PATH and run the installer following the Download page instructions to download composer.phar.

    Create a new composer.bat file alongside composer.phar:

    C:\bin>echo @php "%~dp0composer.phar" %*>composer.bat

    Add the directory to your PATH environment variable if it isn't already. For information on changing your PATH variable, please see this article and/or use Google.

    Close your current terminal. Test usage with a new terminal:

    C:\Users\username>composer -V
    Composer version 1.0.0 2016-01-10 20:34:53

    Using Composer#

    Now that you've installed Composer, you are ready to use it! Head on over to the next chapter for a short and simple demonstration.
