I am reading in a csv file and it has a control character ^M at the end

$a=~s/\^M//;

Any help appreciated thanks.

 

This is an MS-DOSsy file, where each line is terminated by the famous 
CR/LF combination. "^M" is the carriage return. Between the regex 
slashes ("the jungle") "^" means "beginning of line", so what you have 
instructed regex to do is erase any capital "M" that happens to occur at 
the beginning of a line.

If you have a copy of the program dos2unix around, it will take care of 
this for you, otherwise you can try $a =~ s/\x0D//;

which means replace any CR you find with null. HTH.
