Into What Directory should user Bash Scripts - either tutorial or purposeful - GO? Single, Multiple, whatever? Thank you for this concise, specific and stunningly simple tutorial which I will unpack and digest over the coming days.

Hi @wogelsby, it doesn't really matter where the scripts are located, as long as you follow the instructions for setting the proper permissions on them. Some tutorials will tell you to make a bin directory and put that in your path, but it's not necessary.

Well written article! 😎

Elegant set I’ll recommend it for every bash newcomer. ;)

@wogelsby that may depend on used OS and/or used additional package manager(s) in it.

Fastest check in your terminal $PATH like:

cat /etc/paths

and/or

echo $PATH

Most popular (i.e. on MacOS)

/usr/local/bin or /usr/local/sbin

For learning, teaching, private

On the other hand for learning, teaching and private-usage purposes I also suggest creating bin and sbin folders in your $HOME like:

mkdir $HOME/bin
mkdir $HOME/sbin

Exporting paths

in your $HOME/.profile (or $HOME/.bash_profile, depending on OS) export these paths like:

export PATH=$HOME/bin:$HOME/sbin:$PATH

back to the terminal, open a new window to include new exports, or source them in the current window like:

source $HOME/.profile
# or
# source $HOME/.bash_profile

check if your exports are included:

echo $PATH

You should see your new exported paths among others like /Users/you/bin:/Users/you/sbin:<other>

Then all scripts placed in $HOME/bin or $HOME/sbin will be available, just to remember to chmod +x after touching ;)

note

I deliberately use $HOME instead of ~ in this description, although personally I prefer the last one, the first is probably safer depending on OS.

Very great article Tiana. I am newbie to bash scripting. sometimes i get confused with some flags. for instance if [-z ls 4]. what's the meaning of -z?

Hey Tania, I think there's a typo on the output of this command:

echo -e "This string has a \new line"

It should be:

This string has a
ew line
