Install WordPress on Linux in 5 Seconds

WordPress is available on WordPress.org in two formats, .zip and .tar.gz: I wanted an option to download and extract WordPress as easily as possible. I had looked for a way to do this with the zip format but apparently Archives read from standard input are not yet supported, except with funzip (and then only the first member of the archive can be extracted). (source So, my solution was to use WordPress’ latest.tar.gz file and pipe it (stdin/stdout). Running the following command will create a wordpress folder in your current working directory with all files: wget -O – http://wordpress.org/latest.tar.gz | gzip -c -d | tar -x Notes: wget -O – //send output to stdout, use – before the URL gzip -c -d //read from stdin, decompress tar -x // extract, could probably also use -v to verify

wget: no retries

Wget – is the non-interactive network downloader, and you can set it up to download without retrying / making any retries with the following option: -t number / –tries=number: Set number of retries to number. Specify 0 or ‘inf’ for infinite retrying. The default is to retry 20 times, with the exception of fatal errors like “connection refused” or “not found” (404), which are not retried. It is usually also helpful to set up a timeout for requests which may take a long time: -T seconds / –timeout=seconds: Set the network timeout to seconds seconds. This is equivalent to specifying ‘–dns-timeout’, ‘–connect-timeout’, and ‘–read-timeout’, all at the same time. When interacting with the network, Wget can check for timeout and abort the operation if it takes too long. This prevents anomalies like hanging reads and infinite connects. The only timeout enabled by default is a 900-second read timeout. Setting a timeout to 0 disables it altogether. Unless you know what you are doing, it is best not to change the default timeout settings. All timeout-related options accept decimal values, as well as subsecond values. For example, ‘0.1’ seconds is a legal (though unwise) choice of timeout. Subsecond timeouts are useful for checking server response times or for testing network latency.
