Problem with AWK.

Hi,

I am splitting file on each HEADER. I am using following command.

Code:
awk '/^HEADER/{close("file"f);f++}{print $0 > "FILE_"f}' $Filename

I want to use a variable while generating output file. like in above command, splitted files have name "FILE_1", "FILE_2" , "FILE_3" and so on.

I dont want to use "FILE_", I want some variable that I can use instead ... like DATETIME or any run time value. I tried placing variables in place of "FILE_" but it was not working.

Please advice how can I do this.

Thanks.

Try this.

Code:
 
var=`date +"%d%m%Y"`
 
awk '/^HEADER/{close("file"f);f++}{print $0 > '$var'"_FILE_"f}' $Filename

Hi Franklin52,
Your code generates only one file whereas it should generate 4 files.

Hi lathavim,
I tried with var=`date +"%m%d%y%H%M%S"` in your code and the filename generated was "7.2709e+10_FILE_1" (exponential value)
also it working with numbers not with Characters...

Do you have the word "HEADER" on the start of every header? Post a sample of your input file within code tags.
