Installing Sh-utils-2.0

Estimated build time:           2 minutes
Estimated required disk space:  11 MB

Installation of Sh-utils

Install Shellutils by running the following commands:

./configure --prefix=/usr &&
make &&
make install &&
cd /usr/bin &&
mv basename date echo false hostname /bin &&
mv pwd sleep stty su test true uname /bin &&
mv chroot ../sbin

FHS compliance notes

There is a command installed in this package which is named test. It is often used in shell scripts to evaluate conditions, but is more often encountered in the form of [ condition ]. These brackets are built into the bash interpreter, but the FHS dictates that there should be a [ binary. We create that in this way, while still in the /usr/bin directory:

cd /bin &&
ln -sf test [
