Parsing ENV['PATH']

It works fine for me. Both with double/single quotes.

How does you initial string looks ?

in the “# do more stuff here” section, are you calling break ?

My PATH env. variable is a long list of ‘:’ separated
paths; however ENV[‘PATH’] only sees the first path.

So, the ‘split’ works fine, it’s the initial string I’m
splitting that is the problem.

What I’m trying to do is find the path to a certain program on my
system, like

@@cleartool = String.new(‘’)
ENV[“PATH”].split(‘:’).each { |path|
@@cleartool = “#{path}/cleartool” if
FileTest.exist?(“#{path}/cleartool”)
}

The problem is that ENV[‘PATH’] doesn’t contain what I expect. When I
run env in
my c shell, I get a line like this:

PATH=/home/pensch/apps/usr/local/bin:/home/pensch/apps/htmldoc/bin:/home/pensch/bin:/apps/java/j2re1.4.1_01/bin…

so splitting on ‘:’ I feel should get the paths I want. However, running
the script
on Solaris w/ C shell, ENV[‘PATH’] doesn’t contain this string

puts ENV[‘PATH’] prints ‘/home/pensch’

The same script on my Linux box (bash) gets the expected result.

I’m stumped. Any ideas?

As to why your path appears to be incomplete I couldn’t tell you.
However, what you’re trying to accomplish sounds like the “which”
command. You can find File.which in the “ptools” package on the RAA, or
on RubyGarden as “FileWhich”.
