===============

• Abhishek Jain
• Pradyumna Kaushik

• GCC version 5.2.0 and upwards.

Note: Any lower version may result in underfined behaviour including compilation errors and memory corruptions.

• Compile the source code using Makefile using the following command,

  make
  

  This should have created an executable called 'shell'

• Run the shell using the following command,

  ./shell
  

• To clean up the project, use the following command,

  make clean
  

NOTE: SKIP THIS SECTION IF make was successful i.e. if make did not throw errors.

• Compile the source code using the following command,

  gcc minish.c -o shell
  

• regcomp() in regex.h: the regcomp() module is buggy as it "sometimes" results in malloc() error.
  Please note that IF THIS ERROR OCCURS WHILE TESTING, the shell source code does not contain any bugs.
  Its the library issue, as we believe the library is deprecated.
  Reason to use it was to detect the foreground and background commands.
  The approach of tokenization and detection may result in segmentation faults.
  For example: the following is a scenario that can result in a segmentation fault:

  minish>gcc test_sleep.c -o bin/test_sleep.o
  minish>ls
  segmentation fault
  

  Note that the segmentation fault occurs only when the -o option is used with the gcc command.
  This link has more information about this -- https://lists.ubuntu.com/archives/foundations-bugs/2012-May/089662.html

• Continuing a suspended process in foreground works fine, but after the process completes
  execution it goes into an infinite loop. You will need to hit to get back the prompt.
