CP(1)							      General Commands Manual							     CP(1)

NAME

       cp, mv  - copy, move files

SYNOPSIS

       cp file1 file2
       cp file ... directory

       mv file1 file2
       mv file ... directory

DESCRIPTION

       In  the	first form file1 is any name and file2 is any name except an existing directory.  In the second form the commands copy or move one
       or more files into a directory under their original file names, as if by a sequence of commands in the first form.  Thus is equivalent to

       Cp copies the contents of plain file1 to file2.	The mode and owner of file2 are preserved if it already exists; the mode of file1 is  used
       otherwise.

       Mv  moves  file1 to file2.  If the files are in the same directory, file1 is just renamed; otherwise mv behaves like cp followed by rm.	Mv
       will rename directories, but it refuses to move a directory into another directory.

DIAGNOSTICS

       Cp and mv refuse to copy or move files onto themselves.

NAME

       combine - combine sets of lines from two files using boolean operations

SYNOPSIS

       combine file1 and file2

       combine file1 not file2

       combine file1 or file2

       combine file1 xor file2

       _ file1 and file2 _

       _ file1 not file2 _

       _ file1 or file2 _

       _ file1 xor file2 _

DESCRIPTION

       combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:

       and Outputs lines that are in file1 if they are also present in file2.

       not Outputs lines that are in file1 but not in file2.

       or  Outputs lines that are in file1 or file2.

       xor Outputs lines that are in either file1 or file2, but not in both files.

       "-" can be specified for either file to read stdin for that file.

       The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
       for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
       same as "b and a". To obtain commutative behavior sort and uniq the result.

       Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
       test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
