Hi all...
(This is Don's domain.)
I have come across an anomaly in sh and dash compared to bash.
It involves echoing a character set to a file in sh and dash compared to bash.
It is probably easier to show the code and results first.
#!/usr/local/bin/dash

assert
ASSERT(3) BSD Library Functions Manual ASSERT(3)
NAME
assert -- expression verification macro
SYNOPSIS
#include <assert.h>
assert(expression);
DESCRIPTION
The assert() macro tests the given expression and if it is false, the calling process is terminated. A diagnostic message, consisting of the
text of the expression, the name of the source file, the line number and the enclosing function, is written to stderr and the abort(3) func-
tion is called, effectively terminating the program.
If expression is true, the assert() macro does nothing.
The assert() macro may be removed at compile time with the cc(1) option -DNDEBUG.
DIAGNOSTICS
The following diagnostic message is written to stderr if expression is false:
"assertion "%s" failed: file "%s", line %d, function "%s"
",
"expression", __FILE__, __LINE__, __func__);
SEE ALSO
cc(1), _DIAGASSERT(3), abort(3)
STANDARDS
The assert() macro conforms to ISO/IEC 9899:1999 (``ISO C99'').
HISTORY
A assert macro appeared in Version 6 AT&T UNIX.
Information on the name of the enclosing function appeared in ISO/IEC 9899:1999 (``ISO C99'').
