Hi Everyone,
I have:
$val="QQ3_1899_CD4".
The output will be:
1899.

SYNOPSIS

DESCRIPTION
writes its arguments separated by blanks and terminated by a new-line on the standard output. It also understands C-like escape conven-
tions; beware of conflicts with the shell's use of
write an alert character
backspace

backslash
the 8-bit character whose
ASCII code is the 1-, 2-, 3- or 4-digit octal number n, whose first character must be a zero.
write an 8-bit value that is the zero-, one-, two- or three-digit octal number
num
is useful for producing diagnostics in command files and for sending known data into a pipe.
Notes
Berkeley differs from this implementation. The former does not implement the backslash escapes. However, the semantics of the escape can
be obtained by using the option. The echo command implemented as a built-in function of follows the Berkeley semantics (see csh(1)).

variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5).
