binary/hex output
i want to output something like
2f 00 00 00
but i can't seem to escape characters like i'm used to in some programming languages, so with this:
echo "/\0\0\0" >> outputfile
i actually get
2f 5c 30 5c 30 5c 30 0a
ie the \0 isn't giving me the 00 i need, and in addition it has got an extra couple of bytes on the end - 0a (return carriage?).
obviously i'm going about this the wrong way - any suggestions? thanks.

Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
Thanks (0 Replies)

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)
NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS
-n Do not add the NEWLINE to the output.
