awk - remove ^M characters from file using sed

I have this line inside a file:

ULNET-PA,client_sgcib,broker_keplersecurities
,KEPLER

I try to get rid of that ^M (carriage return) character so I used:

sed 's/^M//g'

However this does remove everything after ^M:

[root@localhost tmp]# vi test
ULNET-PA,client_sgcib,broker_keplersecurities^M,KEPLER

[root@localhost tmp]# sed 's/^M//g' test
ULNET-PA,client_sgcib,broker_keplersecurities

What I want to obtain is:

[root@localhost tmp]# vi test
ULNET-PA,client_sgcib,broker_keplersecurities,KEPLER

Use tr:

tr -d '^M' < inputfile

(Note that the ^M character can be input using Ctrl+VCtrl+M)


EDIT: As suggested by Glenn Jackman, if you're using bash, you could also say:

tr -d $'
' < inputfile
