regex for turning a URL into a real hyperlink (i.e. for posting somewhere that accepts basic html)

sed "s/\([a-zA-Z]*\:\/\/[^ ]*\)\(.*\)/\<a href=\"\1\"\>\1\<\/a\>\2/"
This should work with anything://url.whatever etc etc ;)

What Others Think

This is a good place to note that the dividers on a sed substitute construct can be almost anything. It doesn't have to be a `/` . sed "s_\([a-zA-Z]*\:\/\/[^ ]*\)\(.*\)_\<a href=\"\1\"\>\1\<\/a\>\2_" . Since you have all that "picket fencing" ( `\/` ) and escaping of the parentheses this version will improve the readability.

I agree with unixmonkey365 and suggest to further use single quotes, here. sed 's|\([a-zA-Z]*://[^ ]*\)\(.*\)|<a href="\1">\1</a>\2|'

Cool, just found sed -r 'sT([a-zA-Z]*://[^ ]*)(.*)T<a href="\1">\1</a>\2T'

This is a command-based site through which you will get more kinds of Unix commands. If you are interested in diamond rings learning such commands, this is the best platform for you. Good to see the above one shared here. I am looking here for more updates on that.
