awk help

HI ,

I am trying to validate the source files, before loading them. The validation I am doing is checking the no of columns in the file should be proper, all the source files should have 8 columns, if any source file has less than 8 columns, I have to move the improper source files to a directory called invalid source files.

I started with the below awk, but I am not sure how to move the files with improper columns to a different directory.

awk '{if(NF < 8) {print "Invalid File"} else {print $0}' 1.csv

Can any body suggest how can I do this.

$awk '{if(NF < 8) {print "mv " FILENAME " /tmp/"; exit} else {print $0}}' 1.csv | sh

Hi , Thanks for your quick response.

I have modified the code for checking all the .csv files for proper file format.

find  /edw/data/  -name '*.csv'  | while read FILENAME
awk -F, '{if(NF < 8) {print "mv " FILENAME " /edw/data/incorrect/"; exit}}' 
< "$FILENAME" > | sh

I am getting the below error, where am I doing it wrong.

syntax error near unexpected token `|'

awk -F, '{if(NF < 8) {print "mv " FILENAME " /edw/data/incorrect/"; exit}}' $myfile  | sh

I am getting the below error...,i tried putting the -f option after move but still same issue ,pls tell me where i am doing wrong

mv: illegal option -- T
Usage: mv [-i | -f] [-E{force|ignore|warn}] [--] src target
   or: mv [-i | -f] [-E{force|ignore|warn}] [--] src1 ... srcN directory
