Dash-0.5.3

[Ag. Hatzimanikas]

This is a ticket to record the recent activity (1) around Dash.

Dash was included in the book (revision 6667) with the intention to replace Ash, which is no longer under development ( this will be a separate ticket).

Dash, which stands for 'Debian's Ash', is maintained by Herbert Xu from Debian, is a standard POSIX shell. It can be used for debugging standard POSIX syntax/commands or as a default shell for small systems.

Instructions.

We placed the binary (--bindir=/bin) into the root filesystem. For FHS compliance we used (--mandir=/usr/share/man). We used LC_ALL=C make, for the different behavior of sort command (which is being used during the build), in a locale other than the standard C locale. Example.

echo -e ".\n:" |LC_ALL=el_GR.UTF-8 sort
:
.
echo -e ".\n:" |LC_ALL=C sort
.
:

Binary behavior:
Result without the fix.

$ : ${FOO=foo}
dash: :: not found

Expected result, if FOO wasn't set
$ echo $FOO
foo

See (2) for more information.

Dan submitted a patch about the issue upstream. Note: There will a new release, with this fix and all the patches from the debian unstable. Until then, a patch is pending to be applied in the book. ​http://www.linuxfromscratch.org/~dnicholson/patches/dash-0.5.3-fixes-1.patch
