PS1 (Prompt character) appearing in cat output
RedHat Linux 5.8/Korn Shell

I have text file name /etc/oracle/config.loc. It has the following text
Code:
#Device/file  getting replaced by device +OCR
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+OCR

But , when I open this file using cat , the PS1 character (for prompt) appears as the last character in the last line

Code:
$ PS1='> '
>
> cat /etc/oracle/config.loc
#Device/file  getting replaced by device +OCR
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+OCR
local_only=false>

Changing PS1 to $ sign. As you can see below the dollar sign appears in cat output in the last line

Code:
> PS1='$ '
$
$
$ cat /etc/oracle/config.loc
#Device/file  getting replaced by device +OCR
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+OCR
local_only=false$

But it doesn't happen for all files. For instance, PS1 character doesn't appear in the below file abc.txt
Code:
$ cat abc.txt
hello world

Why is this happening ? How can I fix this ?
