Get rid of newline from shell commands in Ruby

Ruby
1

I am trying to run simple shell commands in my script, but am unable to
get rid of new lines even using chomp or chop.

Is there something I am missing ?

  u=`echo  '#{l}' | cut -d: -f4`.chop()
  p2=`echo '#{l}' | cut -d: -f3`.chop()
  p1=`echo '#{l}' | cut -d: -f2`.chomp()
  h=`echo  '#{l}' | cut -d: -f1`.chop()

Cant get newlines to go !! ??

  path="#{p1}/#{@CODELINEFILTER}#{p2}"
  puts path

Any suggestions ?

You might try using

echo -n

and sidestep the problem completely.

I’m somewhat confused as to why a more rubish construct like:

u,p2,p1,h = l.split(’:’)

is not more appropriate?
