NAME
comm
- select or reject lines common to two files
SYNOPSIS
[-123i
]
file1 file2
DESCRIPTION
The
utility reads
file1
and
file2
which should be
sorted lexically, and produces three text
columns as output: lines only in
file1
lines only in
file2
and lines in both files.
The filename ``-'' means the standard input.
The following options are available:
-1
Suppress printing of column 1.
-2
Suppress printing of column 2.
-3
Suppress printing of column 3.
-i
Case insensitive comparison of lines.
Each column will have a number of tab characters prepended to it
equal to the number of lower numbered columns that are being printed.
For example, if column number two is being suppressed, lines printed
in column number one will not have any tabs preceding them, and lines
printed in column number three will have one.
The
utility assumes that the files are lexically sorted; all characters
participate in line comparisons.
ENVIRONMENT
The
LANGLC_ALLLC_COLLATE
and
LC_CTYPE
environment variables affect the execution of
as described in
environ(7).
