Extracting Wordpress.zip file on Linux server

You can use two command line options to unzip to get your desired result, provided the zip contains no sub directories.

unzip -j -d /my-test-site wordpress-4.1.1.zip

Note that if your zip was of the order:

foo
├── 1
├── 2
├── 3
├── 4
├── 5
├── 6
├── 7
├── 8
├── 9
└── bar
    ├── 1
    ├── 2
    ├── 3
    ├── 4
    ├── 5
    ├── 6
    ├── 7
    ├── 8
    └── 9

Using this option would mean the files contained in foo/bar would clobber (replace the contents of) all files located in foo. I.e, the -j option removes all paths relatives to the file locations in the zip and puts in them in either the current directory (default) or the directory specified by the -d option.

If your zip has sub-directories, your method would be the way to go about extracting that zip file.

You could always alias the command:

alias wp_unzip='mv wordpress-4.1.1.zip /my-test-site && \
    cd /my-test-site && unzip wordpress-4.1.1.zip && \
    mv wordpress/* . && rmdir wordpress'
