Subject: Re: extracting part of a string

Hi,

You can use a regular expression to extract the server names:


text = 'server.corp.abc.com:/vol/test/xyz
server2.corp.def.com:/vol/stage/123
server3.corp.xyz.net:/vol/prod/abc'

servers = text.scan /^\s*([^:\s]+)/
p servers


This looks for the beginning of a line followed by whitespace followed 
by characters, which are neither colons nor whitespace. The latter part 
is then saved.

If you don't like the strings being in subarrays, you can append "map 
&:first".
