Linux SED RegEx replace, but keep wildcards
Question
If I have a string that contains this somewhere (Foo could be anything):
<tag>Foo</tag>
How would I, using SED and RegEx, replace it with this:
[tag]Foo[/tag]
My failed attempt:
echo "<tag>Foo</tag>" | sed "s/<tag>\(.*\)<\\/tag>/[tag]\1[\\/tag]"

Your regex is missing the terminating /
$ echo "<tag>Foo</tag>" | sed "s/<tag>\(.*\)<\\/tag>/[tag]\1[\\/tag]/"
[tag]Foo[/tag]

With this you can replace all types of tags and don't have to be tag specific.
$echo "<tag>Foo</tag>" | sed "s/[^<]*<\([^>]*\)>\([^<]*\)<\([^>]*\)>/[\1]\2[\3]/"
hope this helps.
