How to tell SED to emit output in 8-bit ASCII only?
I have to mangle some "plain ASCII" text file (i.e. 8 bits/characters where the text DOES contain characters like Umlauts and accented characters from the upper 7-bits range, i.e. with hex codes in [128..254]).
For this I am trying to use SED which I downloaded as part of cygwin package (yes, I am doing this one Windoze...).
Alas, SED emits the result using Unicode-16 characters (i.e. 16 bits/characters), which the program for which the output is intended can't handle. Can one tell SED to NOT emit Unicode-16 characters but force it to emit 8-bit characters (Unicode-8) only?
Hi All,
i am using the below perl command to remove the non ascii value,it is working fine.
we need to find the similar solution using the sed command. but i tried it is not working and getting the error.
perl -pe 's/]//g' test.txt
sed is not working.
sed -i 's/]//g'... (11 Replies)
Hello everyone.
I bought a dell laptop (XPS M1330) online which came without a hard drive. There is a Windows Vista Ultimate OEMAct sticker with product key at the bottom case. I checked dell website (here) for this model and it says this model supports both 32 and 64-bit version of Windows... (4 Replies)

Hi,
Here is the issue. From the program snippet I have Base: 0x1800000000, Size: 0x3FFE7FFFFFFFF which are of 40 and 56 bits. SO I used use bignum to do the math but summing them up I always failed having correct result.

Hi gurus,
I have a file in unix with ascii values. I need to convert all the ascii values in the file to ascii characters. File contains nearly 20000 records with ascii values. (10 Replies)
ASCII(1) General Commands Manual ASCII(1)NAME
ascii, unicode - interpret ASCII, Unicode characters
SYNOPSIS
ascii [ -8 ] [ -oxdbn ] [ -nct ] [ text ]
unicode [ -nt ] hexmin-hexmax
unicode [ -t ] hex [ ... ]
unicode [ -n ] characters
look hex /lib/unicode
DESCRIPTION
Ascii prints the ASCII values corresponding to characters and vice versa; under the -8 option, the ISO Latin-1 extensions (codes 0200-0377)
are included. The values are interpreted in a settable numeric base; -o specifies octal, -d decimal, -x hexadecimal (the default), and -bn
base n.
With no arguments, ascii prints a table of the character set in the specified base. Characters of text are converted to their ASCII val-
ues, one per line. If, however, the first text argument is a valid number in the specified base, conversion goes the opposite way. Control
characters are printed as two- or three-character mnemonics. Other options are:
-n Force numeric output.
-c Force character output.
-t Convert from numbers to running text; do not interpret control characters or insert newlines.
Unicode is similar; it converts between UTF and character values from the Unicode Standard (see utf(6)). If given a range of hexadecimal
numbers, unicode prints a table of the specified Unicode characters -- their values and UTF representations. Otherwise it translates from
UTF to numeric value or vice versa, depending on the appearance of the supplied text; the -n option forces numeric output to avoid ambigu-
ity with numeric characters. If converting to UTF , the characters are printed one per line unless the -t flag is set, in which case the
output is a single string containing only the specified characters. Unlike ascii, unicode treats no characters specially.
The output of ascii and unicode may be unhelpful if the characters printed are not available in the current font.
The file /lib/unicode contains a table of characters and descriptions, sorted in hexadecimal order, suitable for look(1) on the lower case
hex values of characters.
EXAMPLES
ascii -d
Print the ASCII table base 10.
unicode p
Print the hex value of `p'.
unicode 2200-22f1
Print a table of miscellaneous mathematical symbols.
look 039 /lib/unicode
See the start of the Greek alphabet's encoding in the Unicode Standard.
