If the records are all of fixed size, dd can be used to insert a newline after them. An example with 4 byte fixed size records:
dd is unaffected by line length limitations. You chould chain this before an awk or grep or what have you.
I assume you meant bs=4 instead of bs=3, but when processing a 1.2Gb file, dd will run noticeably faster with its default block size (512 bytes) or a larger size like bs=1024000. The dd bs=n parameter specifies how many bytes dd will read at a time from its input file and how many bytes at a time it will write to its output file.
With conv=unblock, it is just the conversion buffer size (specified by cbs=n) that determines the output line length produced by the dd utility.
Hi All,
Following is the sample file
and following is the op desired
that is the last entry of each unique first field is required.
My solution is as follows
However the original file has around a million entries and around a 100,000 uniques first fields, so this soln.... (6 Replies)

Hello everyone. Need some help copying a filesystem. The situation is this: I have an oracle DB mounted on /u01 and need to copy it to /u02. /u01 is 500 Gb and /u02 is 300 Gb. The size used on /u01 is 187 Gb. This is running on solaris 9 and both filesystems are UFS.

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.
