Instance

A) Copy the file F1 to F2. If F2 exists, it will be overwritten with F1 content. If F2 does not exist, the F2 is created.

Date > F1 CP F1 F2 CMP F1 F2

b) If the target file exists, indicate whether to overwrite it.

Cp-i F1 F2

c) Copy the file F1 and F2 to the directory D1, D1 must already exist.

mkdir D1 CP F1 F2 d1 ls d1F1  F2

d) Copy all the files in the D1 to D2 by using a wildcard character. The D2 must be already there.

mkdir D2 CP d1/* D2 ls D2F1  F2

e) Copy the D1 directory (and its contents) into the D3 directory. If D3 does not exist, the D3 is created and contains the same content as the D1 directory.

mkdir D3 cp-r D1 D3 ls-r D3d3:d1d3/d1:f1  cp-r d1 d4ls-r d4d4:f1  f2
