Comparing a variable with a string python not working when redirecting from bash script

Question

First I ll show you both the bash and python script  both are in the  bin directory on my mac    The bash script  esh 1        bin bash  echo -n  Enter bash or natural-language command    read INPUT echo  INPUT  gt    USER INPUT txt  INPUT if           then echo Redirected to Python Script  esh 2  cat   USER INPUT txt  else echo Did not redirect to Python Script   fi esh 1   The python script  esh 2        usr bin python2 7  with open   Users bendowling USER INPUT txt    r   as UserInputFile      UserInput   UserInputFile read    UserInputFile   open   Users bendowling USER INPUT txt    w     if UserInput     List contents       UserInputFile write  ls   else      print  Didn t work   UserInputFile close     The bash script takes the user s input  stores it in a temporary file called USER INPUT txt  and checks if it runs correctly  If it doesn t  it calls esh 2  the python script  which reads the USER INPUT txt file  taking the user s input  It then checks if it s equal to the string  List contents   If it is  then it writes  ls  to the text file  It then closes the file  The bash file then cats the command stored in the text file  in the future I will make it run it as a command   The script then starts again   The problem is that when I enter  List contents  into the shell  it doesn t work  thus printing  Didn t work   However  if I go into the text file myself and write  List contents   the python script works and writes  ls  to the text file  I have no clue why this is happening  I would gladly appreciate any help on this matter   Thanks  b3n

When you read   the file  you may get a newline character   n  in your string  Try either  if UserInput strip       List contents     or  if  List contents  in UserInput    Also note that your second file open could also use with   with open   Users     USER INPUT txt    w    as UserInputFile      if UserInput strip       List contents     or if s in f          UserInputFile write  ls       else          print  Didn t work
