output - KSH Resolving Environmental Variables for an Entire File -

I have a list of file names in which the environment variable in them I want to set a variable to read the file line by line and then read in a line, but the environment environment variable is translated into the appropriate environment variable. Even my script is:

  #! / Bin / ksh /test/currentEnv.sh While echoing line line for reading line & lt; $ 1   
 If my source file is:  
  foo1 $ ENVVAR1.csv foo2 $ ENVVAR2.csv foo3 $ ENVVAR3.csv   
 and my environment variables in currentEnv.sh  
  $ ENVVAR1 = Hello; ENVVAR1 $ ENVVAR2 = Export the world; ENVVAR2 $ ENVVAR3 = Export test; ENVVAR3 Export   
 I want the results of the script  
  foo1hello.csv foo2world.csv foo3test.csv   
 current In this, it only removes the original file:  
  foo1 $ ENVVAR1.csv foo2 $ ENVVAR2.csv foo3 $ ENVVAR3.csv   
 edit  
 I was able to get the majority to solve using my files: #! / Bin / ksh  
  /test/currentEnv.sh While reading line eval echo $ line   
 Although some of my variables are in the middle of the string:  
  foo3 $ ENVVAR3_bar.csv   
 this An env variable starts searching for $ ENVVAR3_bar and I do not need it, I want it for output:  
  foo3test_bar.csv    
 
  $ var = value # no var = value #  
 
 
 Yes    
 
 Since underscore is a valid character for a variable name, ksh is trying to extend the named variable  ENVVAR3_bar  : Aus You need to use braces to separate the variable names from the text:  
  foo3 $ ENVVAR3_bar.csv # no foo3 $ {ENVVAR3} _bar.csv # yes
