Make the Script Executable Run the following command to make the script executable:

chmod +x make-slice.sh

Add the Script to Your PATH Move the script to a directory that's in your PATH, or add its directory to your PATH. For example, you can move it to /usr/local/bin:

sudo mv make-slice.sh /usr/local/bin/make-slice 

Make this script executable and move it to a directory in your PATH:

chmod +x fsd 
sudo mv fsd /usr/local/bin/fsd 

#Now you can run your command using:

fsd make-slice
