Work on pipe seperated log file

ruby-talk
1

Hi,
     I have a pipe seperated txt file, i need to read the data and work
on it.
Data looks like this:
file
test1|acount1|emp1
test2|acount2|emp2
test3|acount3|emp3
test4|acount4|emp4

when i say emp3, it should display 'test3' value and so on.

You can use File#foreach to iterate over the lines of the file,
String#split to divide each line in parts, and a Hash or other data
structure to store things for later querying.

You can use CSV and put data in a Hash. This should get you started:

$ ruby19 -r csv -e 'CSV.new(ARGF, col_sep:"|").each{|r| p r}' <<CSV
test1|acount1|emp1
test2|acount2|emp2
test3|acount3|emp3
test4|acount4|emp4
CSV
["test1", "acount1", "emp1"]
["test2", "acount2", "emp2"]
["test3", "acount3", "emp3"]
["test4", "acount4", "emp4"]

Kind regards
