Result is written back to the selection +buffer, where you can paste it into whatever application you want. + +This is useful even for single-line pastes: it removes tabs and any +newline at the end, so e.g. copying a command from a browser into the +shell won't trigger tab-completion or execute the command immediately. + +The selection buffer is read/written using xsel, which must be +installed and available on your PATH. + +xcleanpaste is best used by binding to a key using xbindkeys or +similar, though you can run it from the shell too. + +If you're using keybinding, you probably want at least separate keys +for xcleanpaste with no options and xcleanpaste with the -u option +(URL cleaner; see below). + +=head1 OPTIONS + +=over 4 + +=item B<-e><line-ending> + +Replace line endings with the given string rather than a space. Don't +use a space between the -e and the ending. Beware of shell quoting +rules. + +=item B<-n> + +Replace line endings with the string " \n " rather than a space. This is +space, backslash, lowercase n, space. Equivalent to B<-e ' \n '>. + +=item B<-u> + +Remove CGI arguments from any URLs found in the buffer. Some sites +including tracking info, e.g. https://site.blah/stuff?sessionID=12345, +which you shouldn't be pasting into anything others can see (e.g. IRC +or emails). + +=item B<-v> + +Verbose mode. Shows lines read and written from the xsel instances on +stderr. Not much use with xbindkeys though. + +=back + +Any other arguments are passed to xsel.
