Add a newline to the end of a file

    Description:
     Add a missing newline to the end of a file to placate compilers like gcc 3. 
  

gcc 3.x complains if a source or header file doesn't have a newline at the end:

    $ gcc -c no_eof.c
    no_eof.c:9:2: warning: no newline at end of file

The following snippet will fix that for one or more files: perl -i -pl -eof file1 file2 ...

The following is an alternative approach: perl -i -pe '$_ .= $/ if eof and not /\n/' file1 file2 ...

perlrun

    -i[extension]
      ...

      If no extension is supplied, no backup is made and
      the current file is overwritten.

However, on Dos and some other OSes the extension is mandatory. This is due to the fact that these OSes cannot unlink an open file.

I imagine it's a regular perl, but the platform is something other than Windows.

See perlrun and the latest p5p digest
