Introduction
|
|
============
|
|
|
|
This is GNU Bash, version 4.4. Bash is the GNU Project's Bourne
|
|
Again SHell, a complete implementation of the POSIX 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 spec and a description of the Bash `posix mode'.
|
|
|
|
There are some user-visible incompatibilities between this version
|
|
of Bash and previous widely-distributed versions, bash-4.2 and
|
|
bash-4.3. 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 as published by the Free Software Foundation,
|
|
version 3 of the License (or any later version). For more information,
|
|
see the file COPYING.
|
|
|
|
A number of frequently-asked questions are answered in the file
|
|
`doc/FAQ'.
|
|
|
|
To compile Bash, type `./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.
|
|
|
|
Questions and requests for help with bash and bash programming may be
|
|
sent to the help-bash@gnu.org mailing list.
|
|
|
|
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!
