I need to quickly download an ISO image to my new VMware ESX 4 box and discovered that the cURL utility is now included — pretty handy.
If you have not used cURL, it is similar to wget. However, with no parameters cURL will spew the download to standard out — definitely not what you want in the case of an ISO image. Therefore, the -O option — capital O — can be used to save the downloaded file, preserving the filename. If you happen to be behind a proxy server, don’t forget to set the http_proxy environment variable — standard Linux procedure.
The full man page is also present — if you need to know more, just type “man curl”.
