linux - Extract all variable values in a shell script -

I am debugging an old shell script; I want to see the values ​​of all the variables used, this is a big ugly script that has been used with more than 140 variables. Anyway, I can extract the variable names from the script and put them in a convenient format. I:

  #! / Bin / sh if [$ {BLAH} .... ... .. rm -rf $ {JUNK} .....  
  Reverse    
 
 
 Try running your script as follows : Enable  
  bash -x ./script.bash   
 or  script  setting:  < Pre>  set -x
