Installation

Functions are stored in files named func_foo.sh while scripts are stored in files named foo.

1. Save the files in your ~/bin folder
2. Add /bin folder to your PATH variable, i.e., export PATH=/bin:$PATH
3. In order to be able to use functions, add the following code to your ~/.bashrc file for each function you want to use:

if [ -f ~/bin/func_foo.sh ]; then
  source ~/bin/func_foo.sh
fi

or for a set of functions:

FUNCS="func_foo1.sh
       func_foo2.sh"
for FILE in ${FUNCS}; do
  if [ -f "~/bin/${FILE}" ]; then
    source ~/bin/${FILE}
  fi
done
