.SH DESCRIPTION |
| 28 |
|
.I Rlam |
| 29 |
|
simply joins records (or lines) from multiple inputs, separating them with |
| 30 |
< |
the given separator string (TAB by default). |
| 30 |
> |
the given string (TAB by default). |
| 31 |
|
Different separators may be given for different files by specifying |
| 32 |
|
additional |
| 33 |
|
.I \-t |
| 34 |
|
options in between each file name. |
| 35 |
+ |
Note that there is no space between this option and its argument. |
| 36 |
|
If none of the input files uses an ASCII separator, then no end-of-line |
| 37 |
|
character will be printed, either. |
| 38 |
|
.PP |
| 50 |
|
Similarly, the |
| 51 |
|
.I \-id |
| 52 |
|
and |
| 53 |
< |
.I \-iw |
| 53 |
> |
.I \-ii |
| 54 |
|
options may be used to indicate binary 64-bit doubles or integer words, |
| 55 |
|
respectively. |
| 56 |
< |
If an number is immediately follows any of these options, then it |
| 56 |
> |
The |
| 57 |
> |
.I \-iw |
| 58 |
> |
option specifies 2-byte short words, and the |
| 59 |
> |
.I \-ib |
| 60 |
> |
option specifies bytes. |
| 61 |
> |
If a number is immediately follows any of these options, then it |
| 62 |
|
indicates that multiple such values are expected for each record. |
| 63 |
|
For example, |
| 64 |
|
.I \-if3 |
| 68 |
|
option, no number indicates one line per input record, and numbers |
| 69 |
|
greater than zero indicate that many characters exactly per record. |
| 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 |
+ |
If a |
| 75 |
+ |
.I \-in |
| 76 |
+ |
option is given with a positive integer argument, this will be the |
| 77 |
+ |
maximum number of records that will be read or produced by |
| 78 |
+ |
.I rlam. |
| 79 |
+ |
.PP |
| 80 |
|
A hyphen ('-') by itself can be used to indicate the standard |
| 81 |
|
input, and may appear multiple times. |
| 82 |
+ |
The |
| 83 |
+ |
.I \-u |
| 84 |
+ |
option forces output after each record (i.e., one run through inputs). |
| 85 |
|
.SH EXAMPLE |
| 86 |
|
To join files output1 and output2, separated by a comma: |
| 87 |
|
.IP "" .2i |
| 88 |
< |
rlam -t, output1 output2 |
| 88 |
> |
rlam \-t, output1 output2 |
| 89 |
|
.PP |
| 90 |
|
To join a file with line numbers (starting at 0) and its reverse: |
| 91 |
|
.IP "" .2i |
| 92 |
< |
cnt `wc -l < lam.c` | rlam - -t: lam.c -t\| '!tail -r lam.c' |
| 92 |
> |
cnt `wc \-l < lam.c` | rlam \- \-t: lam.c \-t\| '!tail \-r lam.c' |
| 93 |
|
.PP |
| 94 |
|
To join four data files, each having three doubles per record: |
| 95 |
|
.IP "" .2i |
| 96 |
< |
rlam -id3 -t file1.dbl file2.dbl file3.dbl file4.dbl > combined.dbl |
| 96 |
> |
rlam \-id3 file1.dbl file2.dbl file3.dbl file4.dbl > combined.dbl |
