sed command working inline but not inside bash script

Question

I have this inline sed command:

sed -e 's/^M/\'$'\n/g' filename.txt

which is working inline, but not inside a bash script:

#!/bin/bash
sed -e 's/^M/\'$'\n/g' $1

Removing \'$' from the code doesn't solve the problem (replaces ^M with just an "n").

Cheers, Andrea

Does your real `path/to/filename.txt` contain any spaces? If so, your problem should be resolved by writing `"$1"` instead of just `$1`. — Socowi, Mar 16 '17 at 17:50

In #!/bin/bash you need to use $'\r' instead of ^M

You can use the tr (translate) command

#!/bin/bash
tr -d $'\r' < $1

See: remove ^M characters from file using sed for a solution for removing carriage return

thanks for the reply, actually what I needed was: `tr $'\r' $'\n' < $1` – brownstone Mar 16 '17 at 18:23
