User Commands comm(1)
NAME
comm - select or reject lines common to two files
SYNOPSIS
comm [-123] file1 file2
DESCRIPTION
The comm utility reads file1 and file2, which must be
ordered in the current collating sequence, and produces
three text columns as output: lines only in file1; lines
only in file2; and lines in both files.
If the input files were ordered according to the collating
sequence of the current locale, the lines written will be in
the collating sequence of the original lines. If not, the
results are unspecified.
OPTIONS
The following options are supported:
-1 Suppresses the output column of lines unique to
file1.
-2 Suppresses the output column of lines unique to
file2.
-3 Suppresses the output column of lines duplicated in
file1 and file2.
OPERANDS
The following operands are supported:
file1 A path name of the first file to be compared. If
file1 is -, the standard input is used.
file2 A path name of the second file to be compared. If
file2 is -, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of comm
when encountering files greater than or equal to 2 Gbyte ( 2
**31 bytes).

User Commands comm(1)
EXAMPLES
Example 1: Printing a list of utilities specified by files
If file1, file2, and file3 each contain a sorted list of
utilities, the command
example% comm -23 file1 file2 | comm -23 - file3
prints a list of utilities in file1 not specified by either
of the other files. The entry:
example% comm -12 file1 file2 | comm -12 - file3
prints a list of utilities specified by all three files. And
the entry:
example% comm -12 file2 file3 | comm -23 -file1
prints a list of utilities specified by both file2 and
file3, but not specified in file1.
