Hello,
My perl-cgi program copies by number one-liners (using file I/O) from a list in a file that is in my html directory which can be displayed as a web page. New one-line strings are added or old removed from the list dynamically with buttons on a separate web page. Each chosen one-liner needs to be modified with regexp in order to be passed to a javascript function for display in a text area on this web page. For example, quotes must be removed or re-escaped ($sqlQuery =~ s/\'/\\'/g;).

A character found at the end of some of the one-liners as "^M" must also be removed. It appears only in the unix(html) file in blue, contrasting the adjacent white text. I have no idea of it's origin or meaning. Using the chop function (or $string =~ s/.$//g;) works where this "^M" tail is present, but it's indiscriminate and $string =~ s/\\^M$//g; does nothing (with or without escaping "^"). What's the nature of this blue "^M" character and how do I select it out from the string?

My thanks for any answers.

In reply to A 'strange' character("^M") of contrasting color appearing unexpededly at the end of lines of a unix file. How can it be removed? by lev
