SED substitution question 2

[AnotherAlan]

Hi all,

I need to do some substitutions in php pages after changing my web server.
I have written this, which works;
sed 's:\/opt\/SunOne-6.1\/docs:\/usr\/local\/apache2\/htdocs:g' > appdocs.php.test

However, I also have a directory path that starts /app.

My question is - Is it possible to write one sed statement that can substitute for either occurence of app or opt?

Something like sed 's:\/[opt | app]... blah blah. or would I need to use two sed statements?

Thanks
Alan

Apologies,

Seems as though I didn't search the forum properly.

Oops!

What's up Alan,

You're on the right track.

sed 's/V[app|opt]...' should work.

Hey borne2bash,

Thanks for the reply, you'd think that it should work, but not for me I'm afraid.
I've tried in ksh and bash, but no luck, syntax below

sed 's:\/\[opt|app]\/:\/usr:g'
and
sed 's:\/[opt|app]\/:\/usr:g'

Is it my escaping? Or am I just trying too hard to do something that could quite easily be done with a couple of sed statements?

Cheers for your input though, much appreciated.

Time to go home I think.

Perhaps this ?
sed 's:/[oa]p[tp]/SunOne-6.1/docs:/usr/local/apache2/htdocs:g'

Hope This Helps, PH.

GENIUS, every time PHV, every time.

Thank you very much.
I was getting a little too happy with those escapes!!

Of course now I have to stay at work and play around with sed...

As always, much appreciated.

Just another idea to mull over (I know you have a solution already), but I recently discovered the -r option for GNU sed which allows you to use extended regular expressions, e.g.

[tt]sed 's:/(opt|app)/SunOne-6.1/docs:/usr/local/apache2/htdocs:g' [/tt]

...which is I think what borne2bash was heading for.

Hi

And this is why the explanations are good. We understood your code even with the small error... ;-)

[tt]sed 's:/(opt|app)/SunOne-6.1/docs:/usr/local/apache2/htdocs:g'
[red]/\[/red]
[red]-r[/red][/tt]
