1 | .TH MKPROTO 8 "10 May 1981" |
| 2 | .UC 4 | |
| 3 | .SH NAME | |
| 4 | mkproto \- construct a prototype file system | |
| 5 | .SH SYNOPSIS | |
| 6 | .B /etc/mkproto | |
| 7 | special proto | |
| 8 | .SH DESCRIPTION | |
| 9 | .I Mkproto | |
| 10 | is used to bootstrap a new file system. | |
| 11 | First a new file system is created using | |
| 12 | .IR newfs (8). | |
| 13 | .I Mkproto | |
| 14 | is then used to copy files from the old file system into the new | |
| 15 | file system according to the directions found in the prototype file | |
| 16 | .I proto. | |
| 17 | The prototype file | |
| 18 | contains tokens separated by spaces or | |
| 19 | new lines. | |
| 20 | The first tokens comprise the specification | |
| 21 | for the root directory. | |
| 22 | File specifications consist of tokens | |
| 23 | giving the mode, | |
| 24 | the user-id, | |
| 25 | the group id, | |
| 26 | and the initial contents of the file. | |
| 27 | The syntax of the contents field | |
| 28 | depends on the mode. | |
| 29 | .PP | |
| 30 | The mode token for a file is a 6 character string. | |
| 31 | The first character | |
| 32 | specifies the type of the file. | |
| 33 | (The characters | |
| 34 | .B \-bcd | |
| 35 | specify regular, block special, | |
| 36 | character special and directory files | |
| 37 | respectively.) | |
| 38 | The second character of the type | |
| 39 | is either | |
| 40 | .B u | |
| 41 | or | |
| 42 | .B \- | |
| 43 | to specify set-user-id mode or not. | |
| 44 | The third is | |
| 45 | .B g | |
| 46 | or | |
| 47 | .B \- | |
| 48 | for the set-group-id mode. | |
| 49 | The rest of the mode | |
| 50 | is a three digit octal number giving the | |
| 51 | owner, group, and other read, write, execute | |
| 52 | permissions, see | |
| 53 | .IR chmod (1). | |
| 54 | .PP | |
| 55 | Two decimal number | |
| 56 | tokens come after the mode; they specify the | |
| 57 | user and group ID's of the owner of the file. | |
| 58 | .PP | |
| 59 | If the file is a regular file, | |
| 60 | the next token is a pathname | |
| 61 | whence the contents and size are copied. | |
| 62 | .PP | |
| 63 | If the file is a block or character special file, | |
| 64 | two decimal number tokens | |
| 65 | follow which give the major and minor device numbers. | |
| 66 | .PP | |
| 67 | If the file is a directory, | |
| 68 | .I mkproto | |
| 69 | makes the entries | |
| 70 | .BR . "" | |
| 71 | and | |
| 72 | .B .. | |
| 73 | and then | |
| 74 | reads a list of names and | |
| 75 | (recursively) | |
| 76 | file specifications for the entries | |
| 77 | in the directory. | |
| 78 | The scan is terminated with the | |
| 79 | token | |
| 80 | .BR $ . | |
| 81 | .PP | |
| 82 | A sample prototype specification follows: | |
| 83 | .PP | |
| 84 | .nf | |
| 85 | .in +5 | |
| 86 | d\-\-777 3 1 | |
| 87 | usr d\-\-777 3 1 | |
| 88 | sh \-\-\-755 3 1 /bin/sh | |
| 89 | ken d\-\-755 6 1 | |
| 90 | $ | |

| 99 | fs(5), | |
| 100 | dir(5), | |
| 101 | fsck(8), | |
| 102 | newfs(8) | |
| 103 | .SH BUGS | |
| 104 | There should be some way to specify links. | |
| 105 | .PP | |
| 106 | There should be some way to specify bad blocks. | |
| 107 | .PP | |
| 108 | Mkproto can only be run on virgin file systems. | |
| 109 | It should be possible to copy files into existent file systems. |
