[Help Request] Extracting uri's from mozilla bookmarks backup

[afulldevnull]

Hello Linux Forums,
I recently made the switch from Windows 7 to Ubuntu 10.10. I'm trying to get used to doing some scripting and so I'm trying to extract uri's from firefox backup file.

I can't post what the file contains because I'm not allowed to post urls without making 15 posts first.
I suppose the relevant information is that they begin with http and end at the next "}".

I think I need to pipe cat into grep and then use cut to select the fields.

Something like:

cat bookmarks.json | grep "http" | cut -d } -f 1

needless to say this doesn't work.

Can anyone point me in the right direction?

Much appreciated.

Your syntax is right!
But i suppose the bookmark backup is a single line file, thats why grep doesnt work.

You can try,

cat bookmarks.json | sed 's/\,/\n/g' | grep http | cut -d\" -f4 > new.json

Here the commas are converted to newline and the lines with http are taken and just urls filtered.

Let me know if it went well
