I want to print 2 columns in reverse order.

What I want:

LONGER-NAME-PRINTING,0x8da763b9
NAME-1,0x8da6cec9
LONGER-NAME-PRINTING2,0x8da3e489

What I am getting:

awk 'BEGIN { FS="," } { print $2 ,$1}' eol456.txt 

0x8da763b9E-PRINTING
0x8da6cec9
0x8da3e489E-PRINTING2

Separately they look fine:

awk 'BEGIN { FS="," } { print $1}' eol456.txt

0x8da763b9
0x8da6cec9
0x8da3e489

awk 'BEGIN { FS="," } { print $2}' eol456.txt 

LONGER-NAME-PRINTING
NAME-1
LONGER-NAME-PRINTING2

I am really confused why it is not working as I would expect it to. Any help would be greatly appreciated. Thanks.

Did you check for DOS CRLF endings on your file? See the output of `file eol456.txt` – Inian Sep 23 '22 at 06:19
`awk 'BEGIN { FS="," } { print $2 ,$1}' file` should work fine. You want line to be `0x8da763b9E-LONGER-NAME-PRINTING`? – RavinderSingh13 Sep 23 '22 at 06:19

`awk -F, '{sub(/\r$/, ""); print $2, $1}' file` should work for you – anubhava Sep 23 '22 at 06:24
Inian I checked that and it states "eol456.txt: ASCII text, with CRLF line terminators". – Musik847 Sep 23 '22 at 08:10
RavinderSignh13 I want it to be like this: LONGER-NAME-PRINTING,0x8da763b9 – Musik847 Sep 23 '22 at 08:11
anubhava that worked! I am really confused on how that works though. Could you please elaborate? – Musik847 Sep 23 '22 at 08:12
