Expand shortened URLs

expandurl() { curl -sIL $1 | grep ^Location; }
curl(1) is more portable than wget(1) across Unices, so here is an alternative doing the same thing with greater portability. This shell function uses curl(1) to show what site a shortened URL is pointing to, even if there are many nested shortened URLs. This is a great way to test whether or not the shortened URL is sending you to a malicious site, or somewhere nasty that you don't want to visit. The sample output is from: expandurl http://t.co/LDWqmtDM

What Others Think

Seems that some shorteners return lower case "Location" in headers so perhaps grep -i should be used.
