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

still the same line:

sed -i 's/^M//g' file

when you type the command, for ^M you type Ctrl+VCtrl+M

actually if you have already opened the file in vim, you can just in vim do:

:%s/^M//g

same, ^M you type Ctrl-V Ctrl-M
