Shell Programming and Scripting

Hi Experts,

Is there a way to find whether a file contains ^M character in it?. It's quite obvious to vi, but can this be accomplished using an automated way to find recursively in a directory.

probably i guess the best way would be to

1) Read the file and check if the end of line is ^M
2) If so, then echo saying the file has ^M character
3) Else not

pls correct me if i am wrong

Code:

find . -type f -exec grep -l "^M" {} \;

(the control-m (^M) in the grep is acquired by pressing control-v then control-m - i.e. don't cut and paste the above code, because it won't give you the desired result!)

so what are you going to do after finding there are ^M characters? Ultimately, do you want to remove them? if yes, use the find command together with dos2unix.

thanks much ghostdog74.. yes that's the ultimate goal.. i wud do sed 's/\r//' filename >filename.new

if you have dos2unix, use it. its easier than crafting your own regex.

but i don't :-(

Use tr:

Code:

tr -d '\r' < dosfile > unixfile
