The presence or absence of the which program in the main LFS book is probably one of the most contentious issues on the mailing lists. It has resulted in at least one flame war in the past. To hopefully put an end to this once and for all, presented here are two options for equipping your system with which. The question of which “which” is for you to decide.
The first option is to install the actual GNU which package.

Download (FTP): ftp://ftp.gnu.org/gnu/which/which-2.16.tar.gz

Estimated disk space required: 940 KB
Estimated build time: less than 0.1 SBU
Install which by running the following commands:
./configure --prefix=/usr && make
This package does not come with a test suite.
Now, as the root user:
make install
The second option (for those who don't want to install the package) is to create a simple script (execute as the root user):
cat > /usr/bin/which << "EOF" #!/bin/bash type -pa "$@" | head -n 1 ; exit ${PIPESTATUS[0]} EOF chmod -v 755 /usr/bin/which chown -v root:root /usr/bin/which
This should work OK and is probably the easiest solution for most cases, but is not the most comprehensive implementation.
