NAME
comm - select or reject lines common to two files
SYNOPSIS
/usr/bin/comm [-123] [--check-order|--nocheck-order][--output-delimiter=STR] [--help] file1 file2
DESCRIPTION
comm reads two files file1 and file2 which should be ordered in the
collating sequence of the current locale, and produces three text col‐
umns as output:
1 Lines only in file1.
2 Lines only in file2.
3 Lines in both files.
If lines in either file are not ordered according to the collating
sequence of the current locale, the behavior is dependent on the order
option specified.
--nocheck-order No error will be raised about the sort order. Output
will be invalid.
--check-order If any line in either file1 or file2 does not appear
in sorted order an error will occur, regardless of
whether the line if file1 matches the corresponding
line in file2.
If no order option is specified, the default behavior is not to check
the sort order of the input. This is identical to specifying the
--nocheck-order option.
If either file1 or file2 is -, comm uses standard input starting at the
current location.
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 dupli‐
cated in file1 and file2.
--check-order Check that the input is correctly sorted,
even if all lines in file1 are matched with
their corresponding line in file2.
--nocheck-order Do not check that the input is correctly
sorted. This is the default behavior.
--output-delimiter=STR Separate columns with STR.
--help Display command usage and exit.
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.
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.
