Hi,
There seems to be a bug in the dash man page, at least in 0.5.7. It reads:
Precision:
An optional period, `.', followed by an optional digit
string giving a precision which specifies the number of digits to appear after
the decimal point, for e and f formats, or the maximum number of *characters*
to be printed from a string (b and s for-
mats); if the digit string is missing, the precision is
treated as zero;
dash behaves cuts to the number of bytes
$ length=10; printf "%.${length}s\n" "eeeeeeeeeeeeeeeeeeeeeeeee"
eeeeeeeeee
$ length=10; printf "%.${length}s\n" "ëëëëëëëëëëëëëëëëëëëëëëëëë”
ëëëëë
The POSIX specification (2008) says:
precision Gives the minimum number of digits to appear for the d, o, i, u, x,
or X conversion specifiers (the field is padded with leading zeros), the number
of digits to appear after the radix character for the e and f conversion
specifiers, the maximum number of significant digits for the g conversion
specifier; or the maximum number of *bytes* to be written from a string in the
s conversion specifier. The precision shall take the form of a ( '.' ) followed
by a decimal digit string; a null digit string is treated as zero.
So it seems to me that “characters” should be changed to “bytes”.
Kind Regards,
