Top Forums UNIX for Dummies Questions & Answers Finding a column in a flatfile Post 12818 by Jimbo on Monday 7th of January 2002 07:08:51 PM

For two columns, it would be:

cut -c20-30,50-60 myfile > newfile

but reversing these:

cut -c50-60,20-30 myfile > newfile

will produce same results! man page indicates to use multiple cuts, then paste back together to get the columns rearranged. Now, how easy would it have been for the cut command to just output the data in the desired order?

So if you want column 2 followed by column 1, I would use awk:

awk '{print substr($0,50,11), substr($0,20,11)'} myfile > newfile

That comma will give you a space separator. Omit it to get the two columns concatenated.
