Capture output of a bash command, parse it and store into different bash
variables
pstrongExplanation:/strong/p pI have a small embash/em script which simply
runs emany/em Linux command (e.g. say codeifconfig/code)/p pThe typical
output of emifconfig/em is something like this:/p precodeeth0 Link

most people usually do is store the ementire/em output into a
file/variable and parse based on that. I however want to know if there is
anyway that I could put emspecific/em parts of the output in more than one
variable (say a embash variable/em called code${IPETH0}/code to carry the
IP address code10.106.145.12/code from emeth0/em and code${IPLO}/code to
carry the IP address code127.0.0.1/code from emlo/em in the above example
emwithout running ifconfig command twice/em)./p pSomething like what
emtee/em command does with the input but I want to do this for the
emoutput/em and store the output into 2 or emmore/em variables in one go.
Any ideas?/p
