| You want to copy the contents of a directory named directory to another directory (/tmp). You also want to preserve timestamps. Which command would you use?
a. cp directory /tmp
b. cp -r directory /tmp
c. cp -a directory /tmp
d. cp -Ra directory /tmp
e. cp -R directory /tmp | |

| No one got it right. The answer is actually d. cp -Ra directory /tmp.
From the man page...
-R Copy directories recursively, and do the right thing when objects other than ordinary files or directories are encountered. | |

| i thought it was -p for 'preserve'. | |

| I read in the man pages & it says:
-a, --archive
same as -dpR
-d = Same as --no dereference --preserve=link
-p = same as --preserve=mode,ownership, timestamps
-R, -r, --recursive
copy directories recursively
So technically "-Ra" would be "Recusive +Dereference Preserve Recursive" | |

| Hmmm... I remember from a book or a guide a while back reading that -a was to preserve timestamps. Could of sworn that was right. Anyway, I'm sorry to cause any confusion. From now on I'll try my darndest to be 110% sure (unlike all the technical books out there.  ) | |

well, i use bsd now, and i used manpage to find out. it may be possible to have different linux flavor have different versions of the same program.
conflict is good, makes you find the right answer, so dont stop. if somebody argues you down and wins, even you learn something new! | |
