Putting values in one lines

Ruby
1

Hi,
Dont know how to explain this.

example , i am doing this

output=cat #{file} | grep "up down" | grep "aenet" | awk '{print $6}'
puts output

So i get this
ae40.0
ae30.0

But i want to output like ae40.0 ae30.0

how can i achieve this ??

Thanks for your help.

First I’d start by not using shell tools for this in a Ruby script (and
btw. the cat is useless). Then we’d need to know the input to come up
with
suggestions.

Hi , the output is coming from a router

require ‘stringio’

f = StringIO.new(<<ENDOFSTRING)
xe-0/0/2.0 up up aenet --> ae1.0
xe-0/0/3 up up
xe-0/0/3.0 up up aenet --> ae1.0

xe-10/0/6.0 up down aenet --> ae40.0
xe-24/0/3.0 up down aenet --> ae30.0
ENDOFSTRING

results = “”

f.each do |line|
md = line.match(/
up
\s*
down
\s*
aenet
.?
–>
\s
(.*)
\n
\z
/xms)

if md
results << $1 << " "
end
end

p results.rstrip

–output:–
“ae40.0 ae30.0”

If you’re hoping to do a pure ruby implementation of this, heed the
others.

If you just need the values, here’s the awk:

awk ‘BEGIN { ORS="" } /up.*down.*aenet/ { print $6 }’ file…

or,

awk -v ORS=’’ ‘/up.*down.*aenet/ { print $6 }’ file…

(you don’t need the cat or either grep)

Ok, well, pure ruby:

lines = IO.readlines(file)
lines.each do |l|
if l.match(/up\s+down\s+aenet/)
print l.split[5], " "
end
end
print “\n”

Okay: one line:

puts IO.readlines(“data”).grep(/up\s+down\s+aenet/).map{|l|
l.split[5]}.join " "

Ok, more compact:

output = []
IO.readlines(“data”).map{|l| output << l.split[5] if
l.match(/up\s+down\s+aenet/) }
puts output.join " "
