Solved. It is a wrong .bashrc file that gives an alias adding the -l switch...

In perl v5.10, as pre-installed on my Ubuntu 64bit 10.04 LTS OS, the 'print' function does not append "\n" after it automatically (which is the right behavior). So the following command:

$ /usr/bin/perl -e 'print 123; print 456'       # v5.10

will print:

123456                                          # no NL appended

But in perl v5.14 in my own folder, 'print' behaves exactly the same as 'say', i.e. it prints a "\n" after it every time:

$ perl -e 'print 123; print 456'                # v5.14

gives the output:

123                                             # NL appended
456

The website says that the only difference between 'print' and 'say' is that 'say' appends NL after the string list while 'print' does not.

Is this a bug behavior of 'print' in perl v5.14 then?
