The exported TSV file of Google Adwords' first five columns are text, they usually should collapse into one cell, a multi-line text cell, but there is no guaranteed way to represent line-break within cells for .tsv file format, thus Google split it to 5 columns. The problem is, with 5 columns of text, there are hardly space to put additional fields while maintain printable output. This script collapses the first five columns of each row into one single multi-line text cell, for console output or direct send to printer.
-1awk -F $'\t' '{printf $1 LS $2 LS $3 LS $4 LS $5; for (i = 7; i < NF; i++) printf $i "\t"; printf "\n--\n";}' LS=$'\n' 'Ad report.tsv' | column -t -s $'\t' -

This command will delete all branches in your git repository other than next and master. I use this to cleanup my git repos after making multiple branches and merging them back into next. It's much faster than individually deleting each expired branch using:
git branch -D <branch_name>-1git branch -D `git branch | awk '{ if ($0 !~ /next|master/) printf "%s", $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).
-1sudo 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)}') -
-1for f in ~/.mcabber/histo/*; do a=`egrep "^(MR|MS)" $f | wc -l`; echo $f: $a | awk -F\/ '{print $6}'; done
-
-1git branch -a | grep "remotes/origin" | grep -v master | awk -F / '{print $3}' | xargs -I % git clone -b % git://github.com/jamesotron/DevWorld-2010-Cocoa-Workshop %
-
First column is number of photos, second column is the focal length. Show Sample Output
-1exiv2 *JPG | grep Focal | awk '{print $5}' | sort -n | uniq -c -
Removes all lines between the lines containing "" and "", including these lines itself Backdrop: Sometimes when working with XML files without an graphical editor, large comment-/annotation-blocks taper the readability to walk through the file. I like to create a copy of such documents without these annotations. As the documentation itself is in documentation tags inside the annotation tags an therefore graphical editors tend to put the annotation tags in their own lines, this command removes all documentations within annotation-tags. Show Sample Output
-1awk "/<xsd:annotation>/{h=1};!h;/<\/xsd:annotation>/{h=0}" annotatedSchema.xsd -
-1ps aux | awk {'sum+=$3;print sum'} | tail -n 1
-
Today many hosts are blocking traditional ICMP echo replay for an "security" reason, so nmap's fast ARP scan is more usable to view all live IPv4 devices around you. Must be root for ARP scanning.
-1nmap -sP -PR -oG - `/sbin/ip -4 addr show | awk '/inet/ {print $2}' | sed 1d` -
find all computer connected to my host through TCP connection Show Sample Output
-1netstat -nut | awk '$NF=="ESTABLISHED" {print $5}' | cut -d: -f1 | sort -u - ‹ First < 48 49 50 51 52 > Last ›
