Hello
I have a file with records...The records have several lines and have start and end born...
This is a template:
LDR is start born and BK is end born...As you see, in this record I have a field 650 with L $$a string and a 0 at the end...I would liek to remove the zero in this file (34000 records) but only for the foeld 650...
Some one knows how to do?
i tried the following:-
sed -e file 's/^@//g' > temp
also tried
sed -e file 's///g' > temp
nothing happened....can someone please tell me wht is wrong???
also someinformation abt the character "^@"(it is ONLY ONE character and NOT TWO characters)
thanx in advance.. (13 Replies)

Can somebody explain why my sed command is not working.
I do the folloinwg:
Generates a binary file to /tmp/x1.out

decodes the file (no problem so far)

UNITS(7) Linux Programmer's Manual UNITS(7)NAME
units, kilo, kibi, mega, mebi, giga, gibi - decimal and binary prefixes
DESCRIPTION
Decimal prefixes
The SI system of units uses prefixes that indicate powers of ten. A kilometer is 1000 meter, and a megawatt is 1000000 watt. Below the
standard prefixes.
Prefix Name Value
y yocto 10^-24 = 0.000000000000000000000001
z zepto 10^-21 = 0.000000000000000000001
a atto 10^-18 = 0.000000000000000001
f femto 10^-15 = 0.000000000000001
p pico 10^-12 = 0.000000000001
n nano 10^-9 = 0.000000001
u micro 10^-6 = 0.000001
m milli 10^-3 = 0.001
c centi 10^-2 = 0.01
d deci 10^-1 = 0.1
da deka 10^ 1 = 10
h hecto 10^ 2 = 100
k kilo 10^ 3 = 1000
M mega 10^ 6 = 1000000
G giga 10^ 9 = 1000000000
T tera 10^12 = 1000000000000
P peta 10^15 = 1000000000000000
E exa 10^18 = 1000000000000000000
Z zetta 10^21 = 1000000000000000000000
Y yotta 10^24 = 1000000000000000000000000
The symbol for micro is the Greek letter mu, often written u in an ASCII context where this Greek letter is not available. See also

Binary prefixes
The binary prefixes resemble the decimal ones, but have an additional 'i' (and "Ki" starts with a capital 'K'). The names are formed by
taking the first syllable of the names of the decimal prefix with roughly the same size, followed by "bi" for "binary".
Prefix Name Value
Ki kibi 2^10 = 1024
Mi mebi 2^20 = 1048576
Gi gibi 2^30 = 1073741824
Ti tebi 2^40 = 1099511627776
Pi pebi 2^50 = 1125899906842624
Ei exbi 2^60 = 1152921504606846976

Discussion
Before these binary prefixes were introduced, it was fairly common to use k=1000 and K=1024, just like b=bit, B=byte. Unfortunately, the M
is capital already, and cannot be capitalized to indicate binary-ness.
At first that didn't matter too much, since memory modules and disks came in sizes that were powers of two, so everyone knew that in such
contexts "kilobyte" and "megabyte" meant 1024 and 1048576 bytes, respectively. What originally was a sloppy use of the prefixes "kilo" and
"mega" started to become regarded as the "real true meaning" when computers were involved. But then disk technology changed, and disk
sizes became arbitrary numbers. After a period of uncertainty all disk manufacturers settled on the standard, namely k=1000, M=1000k,
G=1000M.
The situation was messy: in the 14k4 modems, k=1000; in the 1.44MB diskettes, M=1024000; etc. In 1998 the IEC approved the standard that
defines the binary prefixes given above, enabling people to be precise and unambiguous.
Thus, today, MB = 1000000B and MiB = 1048576B.
In the free software world programs are slowly being changed to conform. When the Linux kernel boots and says
hda: 120064896 sectors (61473 MB) w/2048KiB Cache
the MB are megabytes and the KiB are kibibytes.
