SED switching columns in one file delimited by , I have a file with 65k lines looking like this: Mumford & Sons,Wilder Mind (Deluxe),Believe - Live,02 Oct 2016 10:25 Mumford & Sons,Wilder Mind (Deluxe),Tompkins Square Park,02 Oct 2016 10:19 Mumford & Sons,Wilder Mind (Deluxe),Believe,02 Oct 2016 10:16 Bon Iver,22 A Million,00000 Million,02 Oct 2016 10:06 Bon Iver,22 A Million,____45_____,02 Oct 2016 10:03 Bon Iver,22 A Million,8 (circle),02 Oct 2016 09:58 I have been trying a lot, but I cant get it done. I need it to look like this: Mumford & Sons,Believe - Live,Wilder Mind (Deluxe),02 Oct 2016 10:25 so that second column is switched with the third one. Is there any simple way to do this?

Would this work?

`awk -F, '{A=$3; $3=$2; $2=A; print}' OFS=, yourfile`

Basically `-F` says that you separate columns by `,`, the body switches 2nd with 3rd column, and then you `print` the modified line.
