If join(1) is available on your system, you should use join(1) instead of jmerge.
jmerge(1) will Merge Data Records from Two Delimited Text Files creating One Merged File.
The merge will occur based upon the First Column of each File. Each record on Output will be a concatenation of the corresponding data from both Files based upon Column 1 with a tag indicating if a match was found.
For example if you have the Two Files shown below. This command will produce the results as shown:
% jmerge -d '|' -i key.txt -K stat.txt dat.txt
The Main (key) File (key.txt). Records unique by Column 1:
.-------.-------.
| Col 1 | Col 2 |
|-------+-------|
| 001 | A |
| 002 | B |
| 003 | C |
| 005 | E |
'-------'-------'
The Data File (dat.txt), Multiple Records per Column 1:
.-------.-------.-------.
| Col 1 | Col 2 | Col 3 |
|-------+-------+-------|
| 001 | AA | B12 |
| 001 | AB | B345 |
| 003 | CA | B5 |
| 003 | CB | B67 |
| 004 | DA | B67 |
| 005 | EA | B89 |
| 005 | EB | B100 |
| 005 | EC | B104 |
'-------'-------'-------'
This is the Output File Created, notice the Tag:
.----------------.-------.-------.-------.-------.
| Col 1 with Tag | Col 2 | Col 3 | Col 4 | Col 5 |
|----------------+-------+-------+-------+-------|
| MATCHED: 001 | A | 001 | AA | B12 |
| MATCHED: 001 | A | 001 | AB | B345 |
| MATCHED: 003 | C | 003 | CA | B5 |
| MATCHED: 003 | C | 003 | CB | B67 |
| NO MATCH: 004 | DA | B67 | | |
| MATCHED: 005 | E | 005 | EA | B89 |
| MATCHED: 005 | E | 005 | EB | B100 |
| MATCHED: 005 | E | 005 | EC | B104 |
'----------------'-------'-------'-------'-------'
And this is the Output Match Stats File you can request to be created:
