Samurai Monkey:

OK, it sounds like you have a space at the end of the name of your script. If so, you can rename it like this:

cd begperl
mv newline.pl\  newline.pl

Note: that's one space after the \, and then another to separate that file name from the new file name.

Regarding your next question (what is the ls -lb command), you can use man ls to read the man page for the ls command. When you do so, it should show something like this:

LS(1)                             User Commands                       
+      LS(1)

NAME
       ls - list directory contents

SYNOPSIS
       ls [OPTION]... [FILE]...

DESCRIPTION
       List information about the FILEs (the current directory by defa
+ult).  Sort
       entries alphabetically if none of -cftuvSUX nor --sort.

       Mandatory arguments to long options are mandatory for short opt
+ions too.

       -a, --all
              do not ignore entries starting with .

       -A, --almost-all
              do not list implied . and ..

       --author
              with -l, print the author of each file

       -b, --escape
              print C-style escapes for nongraphic characters

       --block-size=SIZE
              use SIZE-byte blocks.  See SIZE format below

As you can see above, the -b switch tells ls to put C style escapes in the file names where required. Perl and C escapes are basically the same, and since you didn't report any characters after the \, I guessed that it was a space. Here's a simple program to generate a file with a name with escapes in it:

#!/usr/bin/perl -w
open my $FH, '>', "test\ \r\x1b" or die;
print $FH "foo\n";
close $FH;

After I run it, I next run ls -alb to get:

$ ls -alb
total 2
drwxr-xr-x+ 1 301058 Domain Users  0 2010-12-15 14:14 .
drwxr-xr-x+ 1 301058 Domain Users  0 2010-12-15 14:13 ..
-rw-r--r--  1 301058 Domain Users 91 2010-12-15 14:12 foo.pl
-rw-r--r--  1 301058 Domain Users  4 2010-12-15 14:14 test\ \r\033

[download]

Then, to delete it, I just type "rm test" and hit the tab key to get the rest of the filename autocompleted for me, and then I press Enter to get rid of the file:

$ rm test\ ^M^[

[download]

Note how bash displays a carriage-return as ^M and escape as ^[ while ls -b shows them as \r and \033 respectively.
