Re: bash 2.0.2 backquoted text includes final carriage return


Hello,

The original complaint is correct. Here's what happens on Solaris under
bash 2.0.2:

1001> shell
BASH=/usr/local/bin/bash; BASH_VERSION=2.01.0(1)-release

1002> echo -n `hostname` |od -c
0000000   n   i   t   r   o   g   e   n
0000010


Here's the same under Linux:

1001> shell
BASH=/bin/bash; BASH_VERSION=2.02.0(3)-release
1002> echo -n `hostname` |od -c
echo -n `hostname` | od -c
0000000   t   i   t   a   n   i   u   m   .   t   e   k   n   o   w   l
0000020   e   d   g   e   .   c   o   m
0000030


BTW, using $( ... ) instead of ` ... ` (my personal preference) yields the
same results.

Lastly, on page 18 of my copy of the BASH manual (sec. 3.10.2 Command
Substitution), it is explicitly stated that trailing newlines are removed.
