| 17 | _\bU_\bu_\be_\bn_\bc_\bo_\bd_\be and _\bu_\bu_\bd_\be_\bc_\bo_\bd_\be are used to send a binary file via | |
| 18 | uucp (or other) mail. This combination can be used over | |
| 19 | indirect mail links even when _\bu_\bu_\bs_\be_\bn_\bd(1C) is not available. | |
| 20 | ||
| 21 | _\bU_\bu_\be_\bn_\bc_\bo_\bd_\be takes the named source file (default standard | |
| 22 | input) and produces an encoded version on the standard out- | |
| 23 | put. The encoding uses only printing ASCII characters, and | |
| 24 | includes the mode of the file and the _\br_\be_\bm_\bo_\bt_\be_\bd_\be_\bs_\bt for recrea- | |
| 25 | tion on the remote system. | |
| 26 | ||
| 27 | _\bU_\bu_\bd_\be_\bc_\bo_\bd_\be reads an encoded file, strips off any leading and | |
| 28 | trailing lines added by mailers, and recreates the original | |
| 29 | file with the specified mode and name. | |
| 30 | ||
| 31 | The intent is that all mail to the user ``decode'' should be | |
| 32 | filtered through the _\bu_\bu_\bd_\be_\bc_\bo_\bd_\be program. This way the file is | |
| 33 | created automatically without human intervention. This is | |
| 34 | possible on the uucp network by either using _\bs_\be_\bn_\bd_\bm_\ba_\bi_\bl or by | |
| 35 | making _\br_\bm_\ba_\bi_\bl be a link to _\bM_\ba_\bi_\bl instead of _\bm_\ba_\bi_\bl. In each | |
| 36 | case, an alias must be created in a master file to get the | |
| 37 | automatic invocation of _\bu_\bu_\bd_\be_\bc_\bo_\bd_\be. | |
| 38 | ||
| 39 | If these facilities are not available, the file can be sent | |
| 40 | to a user on the remote machine who can uudecode it manu- | |
| 41 | ally. | |
| 42 | ||
| 43 | The encode file has an ordinary text form and can be edited | |
| 44 | by any text editor to change the mode or remote name. | |

| 50 | The file is expanded by 35% (3 bytes become 4 plus control | |
| 51 | information) causing it to take longer to transmit. | |
| 52 | ||
| 53 | The user on the remote system who is invoking _\bu_\bu_\bd_\be_\bc_\bo_\bd_\be | |
| 54 | (often _\bu_\bu_\bc_\bp) must have write permission on the specified | |
| 55 | file. | |
