If there are conflicts, the user should edit the result and delete one

of the alternatives.

Options

-e Don’t warn about conflicts.

-p Send results to standard output instead of overwriting file1.

-q Quiet; do not warn about conflicts.

-A Output conflicts using the -A style of diff3. This merges all

changes leading from file2 to file3 into file1 and generates the

most verbose output.

-E Output conflict information in a less verbose style than -A;

this is the default.

-L label

Specify up to three labels to be used in place of the corre-

sponding filenames in conflict reports. That is:

merge -L x -L y -L z file_a file_b file_c

generates output that looks as if it came from x, y, and z

instead of from file_a, file_b, and file_c.

-V Print version number.

mesg

mesg [option]

Change the ability of other users to send write messages to your

terminal. With no options, display the permission status.

Options

n Forbid write messages.

y Allow write messages (the default).

metamail

metamail [options] [filename]

Normally invisible to users, metamail is used to send and display

rich text or multimedia email using MIME typing metadata. Mail-

reading programs normally call metamail to determine how to

handle the data, but metamail can be called directly by developers

who want to use it
