how to split the string in a file in puppet ruby

[Spriya]

Hi,

I am trying to capture all paths in a text file. for that i am splitting the string into an array and the word with /java to get the paths.

Here is my ruby code

logfile = "/home/weblogic/javaapp.txt"

log = Facter::Util::FileRead.read(logfile)

log.each_line do |line|

unless log.nil?

log.each_line do |line|

   val = line.split(/  /)

    java_path = val.grep(%r!/java!)

    java_count += 1

Facter.add("java_known_weblogic_version#{java_count}") do

 setcode do

   java_path

end

end

Here is my text file

/u01/java/jdk1.7.0_72/jre/bin/java

/u01/java/jdk1.7.0_72/bin/java

/u01/java/jdk1.7.0_65/jre/bin/java

/u01/java/jdk1.7.0_65/bin/java

The facts are returning like this

java_known_weblogic_version1	["/u01/java/jdk1.7.0_72/jre/bin/java\n"]
java_known_weblogic_version10	[]
java_known_weblogic_version11	[]
java_known_weblogic_version12	[]
java_known_weblogic_version13	["/u01/java/jdk1.7.0_65/bin/java\n"]
java_known_weblogic_version14	[]
java_known_weblogic_version15	[]

My question how to eliminate  these []  and need to return only  path /u01/java/jdk1.7.0_65/bin/java?

Anyone please help me

Are those caused by empty lines in the file your are iterating?

If so, you can try and add a

next if line.empty?

early in your log.each_line loop.

HTH,
Felix
