thank you again felipe.vinturin for your quick response

I had (and still have your code severely in mind) but if i use the find<Path> part wouldn't this need to be iterated through a loop in order to access the specific directory out of the 720 in the main directory? (please be aware that i'm a newbie in shell scriptingSmilie )

so the main directory is : /home/datasets/

and in there there are 720 directories....by using the find <path> in order to access the single .txt file (and then in the do-done put these 3 awk commands) wouldn't i have to call every time the find tool to find again the path (e.g. /home/datasets/hour_1/ then /home/datasets/hour_2/ etc..etc..)?

thanks again

hi felipe again, i actually have tried your code by doing this:
Code:
!usr/bin/sh

find /home/tester/datasets/ -name "hour_*.txt" -type f | \

while read fname
do
	fileBaseName = `basename "${fname}" `
	fileDirName = `dirname "${fname}" `

#	echo "fileBaseName: [${fileDirName}][${fileBaseName}] - fname[${fname}]"

	awk '{print $0 > $2".txt"}' fileBaseName
	awk '{print > "n_"FILENAME}' RS= " " "cust_*.txt"
	awk 'FNR>3 {print > "fin_"FILENAME}' "n_cust*.txt"

done


i get errors on fileBaseName and fileDirName and as expected some errors in the awk commands....is the fileBaseName and fileDirName failure has to do that i'm under cygwin?

cheers and thank you again!

zip_source_file - create data source from a file LIBRARY
libzip (-lzip) SYNOPSIS
struct zip_source * zip_source_file(struct zip *archive, const char *fname); "zip_uint64_t start" "zip_int64_t len" DESCRIPTION
The function zip_source_file creates a zip source from a file. zip_source_file opens fname and reads len bytes from offset start from it.

Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error. ERRORS
zip_source_file fails if: [ZIP_ER_INVAL] fname, start, or len are invalid. [ZIP_ER_MEMORY] Required memory could not be allocated. [ZIP_ER_OPEN] Opening fname failed. SEE ALSO
