Change the $domain variable to whichever domain you wish to query.

Works with the majority of whois info; for some that won't, you may have to compromise:

domain=google.com; for a in $(whois $domain | grep "Domain servers in listed order:" --after 3 | grep -v "Domain servers in listed order:"); do echo ">>> Nameservers for $domain from $a

Note that this doesn't work as well as the first one; if they have more than 3 nameservers, it won't hit them all.

As the summary states, this can be useful for making sure the whois nameservers for a domain match the nameserver records (NS records) from the nameservers themselves.

rename file name with fixed length nomeric format pattern

find . -maxdepth 1 -type f -not -iname '*.jpg' -ls |awk '{TOTAL+=$7} END {print int(TOTAL/(1024^2))"MB"}'

With this sentence we can estimate the storage size of all files not named *.jpg on the current directory.

The syntax is based on Linux, for Unix compliance use:

find ./* -prune ! -name '*.jpg' -ls |awk '{TOTAL+=$7} END {print int(TOTAL/(1024^2))"MB"}'

We can change the jpg extension for whatever extension what we need

sudo aptitude remove -P $(dpkg -l|awk '/^ii linux-image-2/{print $2}'|sed 's/linux-image-//'|awk -v v=`uname -r` 'v>$0'|sed 's/-generic//'|awk '{printf("linux-headers-%s\nlinux-headers-%s-generic\nlinux-image-%s-generic\n",$0,$0,$0)}')

Same as 7272 but that one was too dangerous

so i added -P to prompt users to continue or cancel

Note the double space: "...^ii␣␣linux-image-2..."

Like 5813, but fixes two bugs: [1]This leaves the meta-packages 'linux-headers-generic' and 'linux-image-generic' alone so that automatic upgrades work correctly in the future. [2]Kernels newer than the currently running one are left alone (this can happen if you didn't reboot after installing a new kernel).

BASH: Print shell variable into AWK

Alternatively:

export MyVAR=84; awk '{ print ENVIRON["MyVAR"] }'

MyVAR=84; awk '{ print "'"$MyVAR"'" }'

The result of this command is a tar with all files that have been modified/added since revision 1792 until HEAD. This command is super useful for incremental releases.

This one-liner will use strace to attach to all of the currently running apache processes output and piped from the initial "ps auxw" command into some awk.
