Shell Programming and Scripting

Hi,
I trying my first awk script.
I have this:

my code file:

Code:

#!/usr/bin/ksh
BEGIN{FS=","}
{if(FILENAME=="indata.txt") {L=1}}
END{print $1","$2","$3","L","$0}

my example file:

Code:

1,2v3,4,5 
#,2,3,4,5,6,78,9

i got this error:

Code:

 
 syntax error The source line is 3.
 The error context is
 <<<             >>> BEGIN{FS=","}
 awk: Quitting
 The source line is 3.

I tried to run a lot of different codes i always got error in the BEGIN line.
Can someone please tell me what is the error?

sorry for such a basic question but I'm in a rush to do something and probably I'm focusing on the wrong point.


Thanks,

i think u missed awk ' keyword

eg:

awk 'BEGIN { FS = "=" } {ORS = "~"} {if ($1=="END-PROCESS-DESCRIPTION-RECORD") {print "\n"}} { print $2}'

I use it in command line when i do :

Code:

 awk -f gather_files.awk indata.txt

shouldn't this be enought?

I made it working.
I'm doing like this:

Code:

#!/usr/bin/ksh

gzcat *common* | awk '  
BEGIN { FS = "," } ;
{if(isnum($1)) {imsi=$1}{imsi="xpto"}}
END{print imsi",1,"$0}
function isnum(n) { return n ~ /^[+-]?[0-9]+$/ }
' > final

now i just need to implement my logic! i still have 3 hours to do that.
lets hope i get it.

Don't post homework questions on the forum. Please read our rules.

this is not a homework question.
This a a work question that I'm trying to solve.
I don't understand almost nothing about Linux, thats why i asked this. it can look dummy but is not homework.
I have to fix a performance issue reading:
-6 different files.
-Each file splited in 23 parts.
total line: around 800.000.000
i tunned everything excepts the input file.
I measure some times and i think i will get an improvement creating a manipulated input file.

maybe it would be nicer if you ask before posting a comment like that without knowing.

I hate when people assumes some things without checking if that is true.
thanks for you bad comment.

It is my job here on the forums. I close about 5 homework threads every day - your comment about three hours left is what triggered the response. Sorry.
