8.34.1. Installation of Bash

First, fix a race condition if using multiple cores:

sed -i  '/^bashline.o:.*shmbchar.h/a bashline.o: ${DEFDIR}/builtext.h' Makefile.in

Prepare Bash for compilation:

./configure --prefix=/usr                    \
            --docdir=/usr/share/doc/bash-5.1 \
            --without-bash-malloc            \

The meaning of the new configure option:


This option tells Bash to use the readline library that is already installed on the system rather than using its own readline version.

Compile the package:


Skip down to Install the package if not running the test suite.

To prepare the tests, ensure that the tester user can write to the sources tree:

chown -Rv tester .

Now, run the tests as the tester user:

su tester << EOF
PATH=$PATH make tests < $(tty)

Install the package and move the main executable to /bin:

make install
mv -vf /usr/bin/bash /bin

Run the newly compiled bash program (replacing the one that is currently being executed):

exec /bin/bash --login +h


The parameters used make the bash process an interactive login shell and continues to disable hashing so that new programs are found as they become available.

Short Descriptions


A widely-used command interpreter; it performs many types of expansions and substitutions on a given command line before executing it, thus making this interpreter a powerful tool


A shell script to help the user compose and mail standard formatted bug reports concerning bash


A symlink to the bash program; when invoked as sh, bash tries to mimic the startup behavior of historical versions of sh as closely as possible, while conforming to the POSIX standard as well
