Inspiring Lines...!!!

Today gentlemen, I am honored to coach you

More honored to be leading you onto the field of battle

But theres another honor to be bestowed upon you

And that is in the answer that comes with that question:

Who am I? I AM A CHAMPION!

Thats right, and you need to remember that all through this game

I will conquer what has not been conquered

Defeat will not be in my creed

I will believe what others have doubted

I will always endeavor to pull esteem, honor, and respect out of my team

I have trained my mind and my body will follow

Who am I? I AM A CHAMPION!

I will acknowledge the fact that my opponent does not expect me to win

But I will never surrender

Weakness will not be in my heart

I will look to my comrades and to those who are a part of me in this world and those who have trained

me

And I will draw strength from them

Who am I? I AM A CHAMPION!

I will gladly go out into the field of battle

And I will move in everything I can do

And I will reach my field of battle by any means at my disposal

And when I get there, I will arrive violently

I will rip the heart from my enemy, and leave it bleeding on the ground

Because he cannot stop me

Who am I? I AM A CHAMPION!

To my side I have comrades, comrades that have been with me through thick and thin

Who have sacrificed their blood, sweat and tears

Never will I let them fall, never will I let them down, and I will never leave an enemy behind

Because our opponent does not know my heart

Who am I? I AM A CHAMPION!

No one will deny me, no one will define me

And no one will tell me who and what I am and can be

Belief will change my world

It has moved continents, it has moved countries, it has put men on the moon

And it will carry me through this battle

Who am I? I AM A CHAMPION!

Defeat, retreat: those are not in my words

I dont understand those definitions

I dont understand when things go wrong

I dont understand mistakes

But I do understand this:

I understand victory,

And I understand never surrendering

No matter how bad things go my heart and my mind will carry my body through limits and weakness

Who am I? I AM A CHAMPION!

Today will be that day

Not tomorrow, not next week, but right now, right here

In your house and in your homes

Who am I? I AM A CHAMPION!

History will remember me

I will not let worrying affect my cause

I will define myself

I will write my own pages

And no one will tell me what I cannot be

I will never give up

Not until Ive given everything I got

Because who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Who am I? I AM A CHAMPION!

Awk Introduction Tutorial – 7 Awk Print Examples

Awk Introduction and Printing Operations

Awk is a programming language which allows easy manipulation of structured data and the generation of formatted reports. Awk stands for the names of its authors “Aho, Weinberger, and Kernighan”

The Awk is mostly used for pattern scanning and processing. It searches one or more files to see if they contain lines that matches with the specified patterns and then perform associated actions.

Some of the key features of Awk are:

• Awk views a text file as records and fields.
• Like common programming language, Awk has variables, conditionals and loops
• Awk has arithmetic and string operators.
• Awk can generate formatted reports

Awk reads from a file or from its standard input, and outputs to its standard output. Awk does not get along with non-text files.

Syntax:

awk '/search pattern1/ {Actions}
     /search pattern2/ {Actions}' file

In the above awk syntax:

• search pattern is a regular expression.
• Actions – statement(s) to be performed.
• several patterns and actions are possible in Awk.
• file – Input file.
• Single quotes around program is to avoid shell not to interpret any of its special characters.

Awk Working Methodology

1. Awk reads the input files one line at a time.
2. For each line, it matches with given pattern in the given order, if matches performs the corresponding action.
3. If no pattern matches, no action will be performed.
4. In the above syntax, either search pattern or action are optional, But not both.
5. If the search pattern is not given, then Awk performs the given actions for each line of the input.
6. If the action is not given, print all that lines that matches with the given patterns which is the default action.
7. Empty braces with out any action does nothing. It wont perform default printing operation.
8. Each statement in Actions should be delimited by semicolon.

Let us create employee.txt file which has the following content, which will be used in the
examples mentioned below.

$cat employee.txt
100  Thomas  Manager    Sales       $5,000
200  Jason   Developer  Technology  $5,500
300  Sanjay  Sysadmin   Technology  $7,000
400  Nisha   Manager    Marketing   $9,500
500  Randy   DBA        Technology  $6,000

Awk Example 1. Default behavior of Awk

By default Awk prints every line from the file.

$ awk '{print;}' employee.txt
100  Thomas  Manager    Sales       $5,000
200  Jason   Developer  Technology  $5,500
300  Sanjay  Sysadmin   Technology  $7,000
400  Nisha   Manager    Marketing   $9,500
500  Randy   DBA        Technology  $6,000

In the above example pattern is not given. So the actions are applicable to all the lines.
Action print with out any argument prints the whole line by default. So it prints all the
lines of the file with out fail. Actions has to be enclosed with in the braces.

Awk Example 2. Print the lines which matches with the pattern.

$ awk '/Thomas/
> /Nisha/' employee.txt
100  Thomas  Manager    Sales       $5,000
400  Nisha   Manager    Marketing   $9,500

In the above example it prints all the line which matches with the ‘Thomas’ or ‘Nisha’. It has two patterns. Awk accepts any number of patterns, but each set (patterns and its corresponding actions) has to be separated by newline.

Awk Example 3. Print only specific field.

Awk has number of built in variables. For each record i.e line, it splits the record delimited by whitespace character by default and stores it in the $n variables. If the line has 4 words, it will be stored in $1, $2, $3 and $4. $0 represents whole line. NF is a built in variable which represents total number of fields in a record.

$ awk '{print $2,$5;}' employee.txt
Thomas $5,000
Jason $5,500
Sanjay $7,000
Nisha $9,500
Randy $6,000

$ awk '{print $2,$NF;}' employee.txt
Thomas $5,000
Jason $5,500
Sanjay $7,000
Nisha $9,500
Randy $6,000

In the above example $2 and $5 represents Name and Salary respectively. We can get the Salary using  $NF also, where $NF represents last field. In the print statement ‘,’ is a concatenator.

Awk Example 4. Initialization and Final Action

Awk has two important patterns which are specified by the keyword called BEGIN and END.

Syntax: 

BEGIN { Actions}
{ACTION} # Action for everyline in a file
END { Actions }

# is for comments in Awk

Actions specified in the BEGIN section will be executed before starts reading the lines from the input.
END actions will be performed after completing the reading and processing the lines from the input.

$ awk 'BEGIN {print "Name\tDesignation\tDepartment\tSalary";}
> {print $2,"\t",$3,"\t",$4,"\t",$NF;}
> END{print "Report Generated\n--------------";
> }' employee.txt
Name Designation Department Salary
Thomas   Manager   Sales           $5,000
Jason   Developer   Technology   $5,500
Sanjay   Sysadmin   Technology   $7,000
Nisha   Manager   Marketing   $9,500
Randy   DBA     Technology   $6,000
Report Generated
--------------

In the above example, it prints headline and last file for the reports.

Awk Example 5. Find the employees who has employee id greater than 200

$ awk '$1 >200' employee.txt
300  Sanjay  Sysadmin   Technology  $7,000
400  Nisha   Manager    Marketing   $9,500
500  Randy   DBA        Technology  $6,000

In the above example, first field ($1) is employee id. So if $1 is greater than 200, then just do the default print action to print the whole line.

Awk Example 6. Print the list of employees in Technology department

Now department name is available as a fourth field, so need to check if $4 matches with the string “Technology”, if yes print the line.

$ awk '$4 ~/Technology/' employee.txt
200  Jason   Developer  Technology  $5,500
300  Sanjay  Sysadmin   Technology  $7,000
500  Randy   DBA        Technology  $6,000

Operator ~ is for comparing with the regular expressions. If it matches the default action i.e print whole line will be  performed.

Awk Example 7. Print number of employees in Technology department

The below example, checks if the department is Technology, if it is yes, in the Action, just increment the count variable, which was initialized with zero in the BEGIN section.

$ awk 'BEGIN { count=0;}
$4 ~ /Technology/ { count++; }
END { print "Number of employees in Technology Dept =",count;}' employee.txt
Number of employees in Tehcnology Dept = 3

Then at the end of the process, just print the value of count which gives you the number of employees in Technology department.
