echo $ENCODEDThis command line percent-encodes strings, even binary data. You can use redirection. I used `echo -n` because I didn’t want a newline (%0A) tagged onto the end. I’ll be using this in a bash script to send HTTP POST data via curl.
My result is based on Perl URL Encode & Decode String, modified to be run on the command line and updated to skip the four non-alphanumeric unreserved characters specified in RFC 3986 Section 2.3.
I don’t know if this depends on Perl multibyte settings or anything else. I might have just been lucky. Perl isn’t my thing.

Thanks!

/ January 14, 2009you don’t need to do this, curl encodes the data: curl -d “option=arg”

curl –data-urlencode “paramName=param&=?/:=Value” http://www.example.com
