"csv" means "comma separated values". There are no commas in your "test.csv" file, so I'll assume your file looks like the one in the following excerpt -

Code:
$
$
$ # show the content of the csv file "f3"
$
$ cat f3
name,price,descriptor
Car,50,Mustang
Car_,70,Audi A5
Bike,30,BMW)
SUV@,80,Fortuner+_
Car,75,Sierra
$
$ # run the awk one-liner to process "f3"
$
$ awk -F, 'NR>1 {if ($1 !~ /^[a-zA-Z0-9 ]+$/ || $3 !~ /^[a-zA-Z0-9 ]+$/){print $0 >"f3.err"} else {print $0 >"f3.tmp"}}' f3 ; mv f3.tmp f3
$
$ # show the content of the error file "f3.err"
$
$ cat f3.err
Car_,70,Audi A5
Bike,30,BMW)
SUV@,80,Fortuner+_
$
$ # show the content of the updated csv file "f3"
$
$ cat f3
Car,50,Mustang
Car,75,Sierra
$
$
