perl - Using one grep operation instead of two? -
is there efficient way use grep
in following command running, since want use perl's grep
?
@found = grep { !/$ip/ } `$ssh $ips[0] netstat -aan | /bin/grep 1010`;
basically, connecting fileserver, executing netstat
command , grep ip addresses containing 1010. on output need use grep
find specific ip address. can done somehow using 1 perl command?
sure, can this:
@found = grep { /1010/ && !/$ip/ } `$ssh $ips[0] netstat -aan`;
the condition use in grep
can not arbitrary expression, full block of code if need be.
