					|  |  |  | # General Usage: | 
			
		
	
		
			
				
					|  |  |  | # | 
			
		
	
		
			
				
					|  |  |  | #  1. Source this file at the end of your bash profile so as not to interfere | 
			
		
	
		
			
				
					|  |  |  | #     with anything else that's using PROMPT_COMMAND. | 
			
		
	
		
			
				
					|  |  |  | # | 
			
		
	
		
			
				
					|  |  |  | #  2. Add any precmd or preexec functions by appending them to their arrays: | 
			
		
	
		
			
				
					|  |  |  | #       e.g. | 
			
		
	
		
			
				
					|  |  |  | #       precmd_functions+=(my_precmd_function) | 
			
		
	
		
			
				
					|  |  |  | #       precmd_functions+=(some_other_precmd_function) | 
			
		
	
		
			
				
					|  |  |  | # | 
			
		
	
		
			
				
					|  |  |  | #       preexec_functions+=(my_preexec_function) | 
			
		
	
		
			
				
					|  |  |  | # | 
			
		
	
		
			
				
					|  |  |  | #  3. Consider changing anything using the DEBUG trap or PROMPT_COMMAND | 
			
		
	
		
			
				
					|  |  |  | #     to use preexec and precmd instead. Preexisting usages will be | 
			
		
	
		
			
				
					|  |  |  | #     preserved, but doing so manually may be less surprising. | 
			
		
	
		
			
				
					|  |  |  | # | 
			
		
	
		
			
				
					|  |  |  | #  Note: This module requires two Bash features which you must not otherwise be | 
			
		
	
		
			
				
					|  |  |  | #  using: the "DEBUG" trap, and the "PROMPT_COMMAND" variable. If you override | 
			
		
	
		
			
				
					|  |  |  | #  either of these after bash-preexec has been installed it will most likely break. |
