   Hi @tandelDipak,
   
   In order to define custom commands (functions) you can define it in a single line before calling. 
   The BashOperator is not defined to execute a script before running the **bash_command**
   
   **Example:**
   
   ```
   run_this = BashOperator(
       dag=dag,
       task_id='run_bash',
       bash_command="print_my_input() { echo Your input: $1 ; } && print_my_input 222",
   )
   ```
    **Result:**
   {subprocess.py:78} INFO - Your input: 222
