playing with VI editor

This might be helpful to you: How to remove ^M characters (they are end of line DOS's characters) from a file in vi: type this :%s/^V^M//g where ^V is control-v and ^M is control-m. :%s is the basic search and replace command in vi and the command you typed will look like this :%s/^M//g. It will replace what is between the first and second / with what is between the 2nd and 3rd /. Between the first and second slash, we have ^M and between the second and third we have an empty string since we are replacing with an empty string. g: means to replace all occurences.

ssh server
