  • How to exclude all "permission denied" messages from "find"

    Use: find . ! -readable -prune or more generally find ! -readable -prune -o -print to avoid "Permission denied" AND do NOT suppress (other) error messages AND get exit status 0 ("all files are processed successfully") Works with: find (GNU findutils) 4.4.2. Background: The -readable test matches readable files. The ! operator returns true, when test is false. And ! -readable matches not readable directories (&files). The -prune action does not descend into directory. ! -readable -prune can be translated to: if directory is not readable, do not descend into it. The -readable test takes into account access control lists and other permissions artefacts which the -perm test ignores. For find versions without -readable test, you can check permissions: find . ! -perm -g+r,u+r,o+r -prune Adapted from stackoverflow: http://stackoverflow.com/questions/762348/how-can-i-exclude-all-permission-denied-messages-from-find

print character classes

Block known dirty hosts from reaching your machine
Blacklisted is a compiled list of all known dirty hosts (botnets, spammers, bruteforcers, etc.) which is updated on an hourly basis. This command will get the list and create the rules for you, if you want them automatically blocked, append |sh to the end of the command line. It's a more practical solution to block all and allow in specifics however, there are many who don't or can't do this which is where this script will come in handy. For those using ipfw, a quick fix would be {print "add deny ip from "$1" to any}. Posted in the sample output are the top two entries. Be advised the blacklisted file itself filters out RFC1918 addresses (10.x.x.x, 172.16-31.x.x, 192.168.x.x) however, it is advisable you check/parse the list before you implement the rules
