Installation of ksh

Unlike other BLFS packages, you will need to first create a working directory in which to extract the sources and perform the build. Install ksh by running the following commands:

mkdir ksh &&
cd ksh &&
tar -xf ../INIT.2008-02-02.tgz &&
tar -xf ../ast-ksh.2008-02-02.tgz &&
bin/package make

The test suite for this package requires other packages from the AT&T ast software library, namely nmake, in which case, you'd be better to install the ast-base package using the same instructions. The package command will accept a test argument to test the package.

Now, as the root user:

install -v -m755 arch/linux.i386/bin/ksh /bin &&
install -v -m644 arch/linux.i386/man/man1/sh.1 \
    /usr/share/man/man1/ksh.1 &&
install -v -m755 -d /usr/share/doc/ksh-2008-02-02 &&
install -v -m644 lib/package/{ast-ksh,INIT}.html \

Command Explanations

bin/package make: This command rebuilds the ast INIT package and builds the ast ksh package.
