Shell Programming and Scripting

Thanks durden_tyler,
that's more ways to do it that I'll ever need to have

Sorry for little bit of necro...

I have extension to my problem:
protocol doesn't have to be 'http', so it could be anything before '://' signs.

Also, second way more simple thing: how to get url protocol, again anything before '://url.com/blablabla'

Not sure how that fits in here. "necro" = corpse, death, dead tissue etc. (Necro | Define Necro at Dictionary.com) But anyway, I digress.

So here's the same file "f6" again, with a few non-http protocols thrown in:

Code:

$
$ cat -n f6
     1  http://name5.domain.com:8000/file.dat
     2  http://na5me.domain.com:8000/file.dat
     3  http://5name.domain.com:8000/file.dat
     4  http://name.domain.com:8000/file.dat
     5  ftp://name5.domain.com:8000/file.dat
     6  ftp://na5me.domain.com:8000/file.dat
     7  ftp://5name.domain.com:8000/file.dat
     8  ftp://name.domain.com:8000/file.dat
$
$

The Perl script below fetches the word that is between "://" and ".".
If this word has one or more digits at the end, then are left off.
If this word has one or more digits in the middle, or at the beginning, they are retained.

Code:

$
$ perl -lne '/^.*?:\/\/(.*?)\d*\..*$/; print $_,"\t=>\t",$1' f6
http://name5.domain.com:8000/file.dat   =>      name
http://na5me.domain.com:8000/file.dat   =>      na5me
http://5name.domain.com:8000/file.dat   =>      5name
http://name.domain.com:8000/file.dat    =>      name
ftp://name5.domain.com:8000/file.dat    =>      name
ftp://na5me.domain.com:8000/file.dat    =>      na5me
ftp://5name.domain.com:8000/file.dat    =>      5name
ftp://name.domain.com:8000/file.dat     =>      name
$
$

Here's the Perl script that fetches the protocol from the URL -

Code:

$
$ perl -lne '/^(.*?):\/\/(.*?)\d*\..*$/; print $_,"\t=>\t",$1' f6
http://name5.domain.com:8000/file.dat   =>      http
http://na5me.domain.com:8000/file.dat   =>      http
http://5name.domain.com:8000/file.dat   =>      http
http://name.domain.com:8000/file.dat    =>      http
ftp://name5.domain.com:8000/file.dat    =>      ftp
ftp://na5me.domain.com:8000/file.dat    =>      ftp
ftp://5name.domain.com:8000/file.dat    =>      ftp
ftp://name.domain.com:8000/file.dat     =>      ftp
$
$

HTH,
tyler_durden

Thanks,
durden_tyler, looks like perl is way to go

And 'necro', like... to revive topics from the dead. Or maybe it was some other word? Hehe.
