awk tutorial
Hi All,
I am new to this forum , i observed that many complicated problems are solved by using AWK.
Yoda and Vidyadhar85 and others give very quick solution to the problems using AWK.
As i am new to this, its getting tough for me to understand how does the AWK code works , although it gives the desired result , if you guys can share the link for any tutorial where i can read and learn AWK ?
I believe by reading the document of AWK will help me to understand the AWK code that i see in many threads.
Please advise on this.
Thanks
