remove ^M in a file

Shell Programming and Scripting
1

i have a file that was ftp'd and has ^M characters at the end,its a big file and i want some commands that can help me remove it.

2

In vi,

:s/^M//g

for ^M, type ctrl+v+m

3 
sed 's/^M$//'

Sed is almost the same and you also need to type ctrl+v and ctrl+m or it won't work.

4

you can use

dos2unix srcfilename tgtfilename

5

u can use this

tr -d '\015' <filename>
6

you can use dos2unix command also.

Check the man pages for more details.

7 
dos2unix filename.sh

To prevent the problem use the "ascii" command in ftp. The default is "binary" which will copy MSDOS style text file record terminators (carriage-return line-feed) when of course the correct unix text file terminator is just line-feed.
