- PROGRAM:
- MERGE - Merges two sorted files together in various ways.
- USAGE:
- MERGE [<fid] fid [-U] [-R] [-Cn] [-Ln] [-D] [-I] [-F] [-H] [>fid]
- FUNCTION:
- This program merges two sorted files and produces various
- combinations in the output stream.
- The default is to do a straight forward merge of the standard
- input with the named file on the command line to the standard
- output.
-
- Options are:
- -D Output only lines found in both files
- -I Output only lines in the standard input which do not
- match lines in the named file.
- -F Output only lines in the named file which do not
- match lines in the standard input.
- -R Reverse sort order.
- -U Convert to upper case before compare.
- -Cn Column position to start compare. (Default 1.)
- -Ln Maximum length of compare. (Default whole line.)
- -H Display the available options.
- EXAMPLE:
- SORT <LTLFILE |MERGE BIGFILE >NEWFILE
- COMMENTS:
- Options -I and -F may be used together to get all lines
- not in common. This REQUIRES that no repeated lines exist in
- either file. UNIQUE may be used to eliminate repeated lines.
-
- Trying to merge two files which were not sorted the same way or
- not using the same sort criteria (i.e. -C, -L, -R, -U) will not
- give you the desired result.
