Having an entry that is 78 bits long that contains characters is very strange. Most entries in a file are a stream of 8 bit bytes. So, to split your entries (each of which is 9.75 bytes) into 11 byte lines (your 9.75 bytes per entry plus 2 bits for byte packing and a newline so the output is a text file), you're probably going to find writing a C program to read bytes and rotate bits into the proper positions easier than doing it in a shell script.

What two bits should be added to your entries to produce 10 characters (assuming ASCII or EBCDIC) from your input entries?

If your entries are all 78 bits long, why is your grep looking for a varying number of characters before and after the colon and why is the string it is matching varying from 1 to 76 characters (not bits or bytes) inclusive instead of the 78 bits you specified???

Please show us the first 200 bytes of your input file piped through the command:
Code:
od -bcx

install-solaris

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
