- FORMAT
- COMMON [FILE1] file1 [[FILE2] file2] [-1] [-2] [-3]
-
- TEMPLATE
- FILE1/A,FILE2,-1/S,-2/S,-3/S
-
- PURPOSE
- To select or reject lines common to two sorted files.
-
- SPECIFICATION
- The command COMMON reads file1 and file_2, which should be
- ordered in the collating sequence of SORT, and produces a
- three-column output: lines only in file1; lines only in
- file2; and lines in both files.
-
- Switches -1, -2, or -3 suppress printing of the corre-
- sponding column. Thus COMMON -1 -2 prints only the lines
- common to the two files; COMMON -2 -3 prints only the
- lines in the first file but not in the second; COMMON -1
- 1 -2 -3 is a no-op.
-
- If file2 is not given, the default input will be used.
