How to call a function in shell Scripting?

Question

I have a shell script which conditionally calls a function.

For Example:-

if [ \"$choice\" = \"true\" ]
then 
  process_install
elif [ \"$choice\" =          


        

Answer 1

#!/bin/bash  
# functiontest.sh a sample to call the function in the shell script  

choice="true"  
function process_install  
{  
  commands...
}  

function process_exit  
{
  commands...  
}  

function main  
{  
  if [[ "$choice" == "true" ]]; then  
      process_install
  elif [[ "$choice" == "false" ]]; then  
      process_exit  
  fi  
}  

main "$@"  

it will start from the main function
