That doesn't work either...it just deletes all the "R" characters.

You need to escape the CR and make it global. This works better:

sed -i 's/\r\n/\n/g' file.txt

Running the command:

tr -d '1532' < teste.f > teste1.f

Cleans up my ctrl-m's but not the final ctrl-z. Anyone would happen to know why?

all sequences of the form "1532"...that's wrong
for two reasons.

First, "32" is a typo, that's just
a random control character. "12" is the correct
octal escape for newline (and 15 is carriage
return).

15 is r. Yes, you do want to delete all r's.

32 is CTRL-Z. DOS text files have an EOF byte: 0x1a or 32 or ^Z. This also removes that character. Yes, you do want to delete all ^Z's.

So this is good advice and does work. Did you try it?

I do agree with the other poster who said to use -i to edit the file in place, though.

sed is made for these kind of things...

> sed -i "s/r//" file.txt

If you want to keep a backup of the file just specify an extension.

> sed -i.bak "s/r//" file.txt

Above line will create file.txt.bak as a copy of the original file.

The quickest fix is to just delete all carriage
returns, leaving the newlines in place:

tr -d '15" < dos-format-file > unix-friendly-file
or better
tr -d "r" < dos_file > unix_file

There's also "dos2unix", which comes with most
Linux/Unix systems I've seen in the last 10 years:

dos2unix -n dos_file new_unix_file

Or in a singl e shot
perl -pi -s 'rn/n/' filename
dos2unix filename.
