Install Shellutils by running the following commands:
./configure --prefix=/usr && make && make install && cd /usr/bin && mv date echo false pwd stty /bin && mv su true uname hostname /bin && mv chroot ../sbin |
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:
ln -sf test [ |
