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:
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.
I have tried to do it using:... (14 Replies)

encoding(n) Tcl Built-In Commands encoding(n)
__________________________________________________________________________________________________________________________________________________NAME
encoding - Manipulate encodings
SYNOPSIS
encoding option ?arg arg ...?
_________________________________________________________________INTRODUCTION
Strings in Tcl are encoded using 16-bit Unicode characters. Different operating system interfaces or applications may generate strings in
other encodings such as Shift-JIS. The encoding command helps to bridge the gap between Unicode and these other formats.
DESCRIPTION
Performs one of several encoding related operations, depending on option. The legal options are:
encoding convertfrom ?encoding? data
Convert data to Unicode from the specified encoding. The characters in data are treated as binary data where the lower 8-bits of
each character is taken as a single byte. The resulting sequence of bytes is treated as a string in the specified encoding. If
encoding is not specified, the current system encoding is used.
encoding convertto ?encoding? string
Convert string from Unicode to the specified encoding. The result is a sequence of bytes that represents the converted string.
Each byte is stored in the lower 8-bits of a Unicode character. If encoding is not specified, the current system encoding is used.
encoding names
Returns a list containing the names of all of the encodings that are currently available.
encoding system ?encoding?
Set the system encoding to encoding. If encoding is omitted then the command returns the current system encoding. The system encod-
ing is used whenever Tcl passes strings to system calls.
EXAMPLE
It is common practice to write script files using a text editor that produces output in the euc-jp encoding, which represents the ASCII
characters as singe bytes and Japanese characters as two bytes. This makes it easy to embed literal strings that correspond to non-ASCII
characters by simply typing the strings in place in the script. However, because the source command always reads files using the ISO8859-1
encoding, Tcl will treat each byte in the file as a separate character that maps to the 00 page in Unicode. The resulting Tcl strings will
not contain the expected Japanese characters. Instead, they will contain a sequence of Latin-1 characters that correspond to the bytes of
the original string. The encoding command can be used to convert this string to the expected Japanese Unicode characters. For example,
set s [encoding convertfrom euc-jp "xA4xCF"]
would return the Unicode string "u306F", which is the Hiragana letter HA.
