| 13 | [ source ] remotedest | | |
| 14 | .B mail | |
| 15 | sys1!sys2!..!decode | |

| 19 | .SH DESCRIPTION | |
| 20 | .I Uuencode | |
| 21 | and | |
| 22 | .I uudecode | |
| 23 | are used to send a binary file via uucp (or other) mail. | |
| 24 | This combination can be used over indirect mail links | |
| 25 | even when | |
| 8edddc75 | 26 | .IR uusend (1C) |
| e0107ca5 KM |
27 | is not available. |
| 28 | .PP | |
| 29 | .I Uuencode | |
| 30 | takes the named source file (default standard input) and | |
| 31 | produces an encoded version on the standard output. | |
| 32 | The encoding uses only printing ASCII characters, | |
| 33 | and includes the mode of the file and the | |
| 34 | .I remotedest | |
| 35 | for recreation on the remote system. | |
| 36 | .PP | |
| 37 | .I Uudecode | |
| 38 | reads an encoded file, | |
| 39 | strips off any leading and trailing lines added by mailers, | |
| 40 | and recreates the original file with the specified mode and name. | |
| 41 | .PP | |
| 42 | The intent is that all mail to the user ``decode'' should be filtered | |
| 43 | through the uudecode program. This way the file is created automatically | |
| 44 | without human intervention. | |
| 45 | This is possible on the uucp network by either using | |
| 8edddc75 | 46 | .I sendmail |
| e0107ca5 KM |
47 | or by making |
| 48 | .I rmail | |
| 49 | be a link to | |
| 50 | .I Mail | |
| 51 | instead of | |
| 52 | .I mail. | |
| 53 | In each case, an alias must be created in a master file to get | |
| 54 | the automatic invocation of uudecode. | |
| 55 | .PP | |
| 56 | If these facilities are not available, the file can be sent to a | |
| 57 | user on the remote machine who can uudecode it manually. | |
| 58 | .PP | |
| 59 | The encode file has an ordinary text form and can be edited | |
| 60 | by any text editor to change the mode or remote name. | |

| 64 | Mark Horton | |
| 65 | .SH BUGS | |
| 66 | The file is expanded by 35% (3 bytes become 4 plus control information) | |
| 67 | causing it to take longer to transmit. | |
| 68 | .PP | |
| 69 | The user on the remote system who is invoking | |
| 70 | .I uudecode | |
| 71 | (often | |
| 72 | .I uucp) | |
| 73 | must have write permission on the specified file. |
