# t-copy command

The t-copy BASIC program copies data
from one device to another.

## Syntax

```
t-copy source.device dest.device{(file.count}
```

## Parameter(s)

| file.count | Specifies number of file segments to copy. Default is 1 file segment. For example, a file in t-dump format is written on tape as 1 file segment. A file-save or account-save on tape is written as 2 file segments, plus 1 file segment for each account. Therefore, to copy to the first account of a save, specify a file count of 3; to copy the first two accounts, specify a file count of 4; and so on. |

Note: Both source and destination devices must be attached
to the current process.

## Example(s)

```
who

15 dm dm
list-device
```

```

Tape Status 17 Feb 2003 11:46:41
# Type Density Owner Device Name
----------------------------------------------------------------
0 | Floppy | 3 1/2" 1.44M | 15* + | /dev/rpdsk/2
1 | Floppy | 5 1/4" 1.2M | | /dev/rpdsk/3
2 | Quarter Inch | High | 15* | /dev/rmt/0n
```
Copies the contents of device 0 to device 2, up to the third EOF
mark. If device 0 contains data in save format, this copies the first
account on tape.

```
t-copy 0 2 (3
```
Copies up to the first EOF mark (default file count is
1). In this case, if device 0 contains data in t-dump format, this copies the t-dump from device 0
to device 2.

```
t-copy 0 2
```
