With regard to your question on how to pose a cp question, I think htere
are a multitude of possibilities. Take a look at the range of options for
cp and then start thinking about possibilities:
Write the command(s) to
(a) copy the file A from directory B to directory C
(b) copy the file from A from user B's home directory to user C's home
(c) copy the file from A from user B's home directory to user C's home
directory, assuming the home directory of user B is not /home/B
(d) copy the file A from directory B to directory C only if both the B and
C directories are on the same file system
(e) copy the file A from directory B to directory C preserving the
original timestamp fo file A (or any other attribute you choose)
(f) copy the file A from directory B to directory C, removing any existing
file A in directory C before copyign
(g) copy the file A from directory B to directory C even if a non-writable
fiel A exists already in directory C
(h) copy the file A from directory B to directory C if an immutbale file A
already exists in directory C
(i) copy the file A from directory B to directory C and ensure that the
output file is not sparse
(j) copy the file A from directory B to directory C and attempt to make
the output file sparse
(k) copy the file D/A from directory B to directory C creating
subdirectory D if it does nto already exist.
(l) copy the file A from directory B to directory C prompting before
overwriting existing destination files
That's a dozen to start with, all requiring decent knowledge of the cp
command. I wouldn't rank them all of equal difficulty, but that wasn't the
original question. :-)
