Ruby pad IP address with zeros
Not sure why this was so difficult to figure out, but the Googs failed me when I tried to look this up. So here it is for my fellow lazy sysadmins who want IP fields to line up nice and pretty.
##
# For pretty printing, align text with equal char length of IPs
def pad_ip_with_zeros(ipString)
arr = ipString.to_s.split('.')
barr = []
arr.each {|octet|
barr.push(octet.rjust(3,'0'))
}
return barr.join('.')
end #def pad_ip_with_zeros(ipString)
##
# Undo pretty printing of IP address
def unpad_ip_with_zeros(ipString)
arr = ipString.to_s.split('.')
barr = []
arr.each {|octet|
barr.push(octet.to_i)
}
return barr.join('.')
end #def pad_ip_with_zeros(ipString)
