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 previous widely-distributed versions, bash-3.2 and +bash-4.0. 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, 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! + +Chet Ramey +chet.ramey@case.edu + +Copying and distribution of this file, with or without modification, +are permitted in any medium without royalty provided the copyright +notice and this notice are preserved.
