remove ^M characters from file using sed

Question

I have this line inside a file:

ULNET-PA,client_sgcib,broker_keplersecurities
,KEPLER

I try to get rid of that ^M (carriage return) charact

Answer 1

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 $'\r' < inputfile
