Thanks in advance.

You could simply print only the fields you want.

if you want to delete fields in fiels I recommend you to use SED otherwise. Just use AWK and you can pick the fields you want to print.

If you give me more information what you really like to do I can give you a better advice.

If you wanted to delete the 5th field from each line

>awk '{$5=""; print }' filename

do you want it to write to a file?

Or only want to print everything except field 5?

If you dont want second field (presuming space is the delimiter) of 5fields file just do at command prompt...

awk '{print $1,$3,$4,$5}' inputfl > outputfl
