Hi,
Its been a long time friends, since i last posted.
So what's better to reboot the posting spree than Linux.
awk is the focus today.
This post is not supposed to be an extended tutorial, but just a reference for novices and first timers.
awk is not just a simple command, its an interpreter, well atleast sort of.
you can write awk scripts, and rule the world :)
consider a condition in which you want to print the second column of every line of the input, which can be a file or even the output of some command piped through.
ls -l | awk '{print $2}'
this command does it all, takes the input from ls command and prints the 2nd column.
and its just not that you can even use if/for/while etc.
So, jump into the depths of awk.
More is coming.
