Code:
-bash-3.00# echo test >> orig.file
-bash-3.00# cat orig.file
 
test
-bash-3.00# ln orig.file hardlink.file
-bash-3.00# cat orig.file
 
test
-bash-3.00# cat hardlink.file
 
test

both files have same content

Code:
-bash-3.00# echo hard test >> hardlink.file
-bash-3.00# cat hardlink.file
 
test
hard test
-bash-3.00# cat orig.file
 
test
hard test

edit hardlink.file and all content changes

Code:
-bash-3.00# cp orig.file copied.file
-bash-3.00# cat copied.file
 
test
hard test
-bash-3.00# echo copy test >> copied.file
-bash-3.00# cat copied.file
 
test
hard test
copy test
-bash-3.00# cat orig.file
 
test
hard test
-bash-3.00# cat hardlink.file
 
test
hard test

change to copied file doesn't show same with original file but hardlink and orig file show same content.

Thanks for your nice reply,.
