Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Retrieve the size of a file on a server

- Where $URL is the URL of the file.

- Replace the $2 by $3 at the end to get a human-readable size.

Edit: Replaced command with better version by FRUiT. (removed unnecessary grep)

Downloads the entire file, but http servers don't always provide the optional 'Content-Length:' header, and ftp/gopher/dict/etc servers don't provide a filesize header at all.

Know a better way?

If you can do better, submit your command here.

Useless use of grep.......

@ioggstream: Doesn't work for me on bash v4.2.10

Comment by d3Xt3r 140 weeks and 6 days ago

only works if $URL is an http or https protocol, and only if the server sends a Content-Length header.
