.SH DESCRIPTION |
| 28 |
|
.I Rlam |
| 29 |
|
simply joins records (or lines) from multiple inputs, separating them with |
| 38 |
|
.PP |
| 39 |
|
An input is either a stream or a command. |
| 40 |
|
Commands are given in quotes, and begin with an exclamantion point ('!'). |
| 41 |
< |
If the inputs do not have the same number of lines, then |
| 41 |
> |
If the inputs do not have the same number of records, then |
| 42 |
|
shorter files will stop contributing to the output as they |
| 43 |
|
run out. |
| 44 |
|
.PP |
| 65 |
|
indicates three floats per input record for the next named input. |
| 66 |
|
In the case of the |
| 67 |
|
.I \-ia |
| 68 |
< |
option, no number indicates one line per input record, and numbers |
| 69 |
< |
greater than zero indicate that many characters exactly per record. |
| 68 |
> |
option, no number reads one line per record, and numbers |
| 69 |
> |
greater than zero take multiple lines at a time from the same stream. |
| 70 |
|
For binary input formts, no number implies one value per record. |
| 71 |
|
For anything other than EOL-separated input, the default tab separator |
| 72 |
|
is reset to the empty string. |
| 73 |
|
.PP |
| 74 |
+ |
These options may be interspersed with input specifications, |
| 75 |
+ |
indicating different data to draw from the different files. |
| 76 |
+ |
.PP |
| 77 |
+ |
If a |
| 78 |
+ |
.I \-in |
| 79 |
+ |
option is given with a positive integer argument, this will be the |
| 80 |
+ |
maximum number of records that will be read or produced by |
| 81 |
+ |
.I rlam. |
| 82 |
+ |
.PP |
| 83 |
|
A hyphen ('-') by itself can be used to indicate the standard |
| 84 |
|
input, and may appear multiple times. |

To join two data files, the first having two words per |
| 102 |
+ |
record and the second having one: |
