script to read file into array

STAGED · 01-24-2006, 08:32 PM

This c

an't possibly be the first request like this. But I was wondering if there's a nice script already done to something like (i.e., not exactly like) the following:

i.) read a file (consisting of 8 columns separated by spaces)
ii.) generating a file of just the first two columns
iii.) writing the two columns to file

Thanks

here is a quality starting bit.. you figure out the rest.. (which is very little)

`cat a.file | cut -d ' ' -f1,2`

<edit> this had better not have been homework.. i will find your teacher..

Thanks very much. This is not homework, just self-enlightning.

Best regards.

Code:

awk -F" " '{print $1, $2}' oldfile > newfile
