Introduction
============
This is GNU Bash, version 3.1. Bash is the GNU Project's Bourne
Again SHell, a complete implementation of the POSIX.2 shell spec,
but also with interactive command line editing, job control on
architectures that support it, csh-like features such as history
substitution and brace expansion, and a slew of other features.
For more information on the features of Bash that are new to this
type of shell, see the file `doc/bashref.texi'. There is also a
large Unix-style man page. The man page is the definitive description
of the shell's features.
See the file POSIX for a discussion of how the Bash defaults differ
from the POSIX.2 spec and a description of the Bash `posix mode'.
There are some user-visible incompatibilities between this version
of Bash and a previous widely-distributed version, bash-1.14.
For details, see the file COMPAT. The NEWS file tersely lists
features that are new in this release.
Bash is free software, distributed under the terms of the [GNU]
General Public License, version 2. For more information, see the
file COPYING.
A number of frequently-asked questions are answered in the file
`doc/FAQ'.
To compile Bash, try typing `./configure', then `make'. Bash
auto-configures the build process, so no further intervention
should be necessary. Bash builds with `gcc' by default if it is
available. If you want to use `cc' instead, type
CC=cc ./configure
if you are using a Bourne-style shell. If you are not, the following
may work:
env CC=cc ./configure
Read the file INSTALL in this directory for more information about how
to customize and control the build process. The file NOTES contains
platform-specific installation and configuration information.
If you are a csh user and wish to convert your csh aliases to Bash
aliases, you may wish to use the script `examples/misc/alias-conv.sh'
as a starting point. The script `examples/misc/cshtobash' is a
more ambitious script that attempts to do a more complete job.
Reporting Bugs
==============
Bug reports for bash should be sent to:
bug-bash@gnu.org
using the `bashbug' program that is built and installed at the same
time as bash.
The discussion list `bug-bash@gnu.org' often contains information
about new ports of Bash, or discussions of new features or behavior
changes that people would like. This mailing list is also available
as a usenet newsgroup: gnu.bash.bug.
When you send a bug report, please use the `bashbug' program that is
built at the same time as bash. If bash fails to build, try building
bashbug directly with `make bashbug'. If you cannot build `bashbug',
please send mail to bug-bash@gnu.org with the following information:
* the version number and release status of Bash (e.g., 2.05a-release)
* the machine and OS that it is running on (you may run
`bashversion -l' from the bash build directory for this information)
* a list of the compilation flags or the contents of `config.h', if
appropriate
* a description of the bug
* a recipe for recreating the bug reliably
* a fix for the bug if you have one!
The `bashbug' program includes much of this automatically.
If you would like to contact the Bash maintainers directly, send mail
to bash-maintainers@gnu.org.
While the Bash maintainers do not promise to fix all bugs, we would
like this shell to be the best that we can make it.
Enjoy!
