V6(8)               UNIX Programmer's Manual                V6(8)

NAME
     v6 - version 6 UNIX file system access utility

SYNTAX
     v6 [ -r ] special

DESCRIPTION
     _V_6 reads a version 6 UNIX file system present on the block
     special file _s_p_e_c_i_a_l. It reads the root directory of the
     file system, which is then the current directory.  At any
     time there is a current version 6 working directory in addi-
     tion to the current version 7 directory (that in effect at
     the time the program was entered).  _V_6 allows the user to
     change version 6 directories, list their entries, print the
     contents of files on the terminal, and copy them onto a ver-
     sion 7 file system.  It does not include any operations that
     write on or change the version 6 file system.  The -r option
     allows examination of a damaged file system; it suppresses
     the reading of the superblock or the root directory.

COMMANDS
     The available commands are:

     ls [ -i ] [ name ]
                    List entries in directory _n_a_m_e; list current
                    directory if no argument.  -i gives inode
                    numbers of files.

     cd name        Change to (version 6) directory _n_a_m_e.

     cat file       Print version 6 file _f_i_l_e on terminal

     cp file1 file2 Copy version 6 _f_i_l_e_1 to (v7) file _f_i_l_e_2

     cpdir          Copy all files in current v6 directory to
                    current version 7 directory

     printi inumber ...
                    Print the contents of the specified inodes.

     printblk blk   Print the contents of the specified block.

     cpblk file blk ...
                    Copy the specified blocks to v7 file _f_i_l_e.
                    The blocks are appended to the file if it
                    exists, otherwise the file is created.

     rootino inumber
                    Inode _i_n_u_m_b_e_r is taken to be that of the root
                    directory, and the corresponding directory is
                    read.

     !              Escape to the shell; the rest of the line is
                    passed to the shell.

     ?              Print the list of available commmands

     q or ^d        Exit from the program

DIAGNOSTICS
     Invalid command.
     Input line too long.  Input line limited to 80 characters.

BUGS
     It believes the superblock, thus results are unpredictable
     if the file system is not healthy.
     Cpdir is not recursive.
