title: Bash scripting with make
body: <p>I have a makefile which I use to run simple bash scripts inside of a repo I am working on. I am attempting to make a new make call which will log me into my mySQL database automatically. I have my username and password stored in a .zinfo file at a known location (such as "/u/r/z/myid/.zinfo"). I am attempting to read the lines of this file to get my password, which is of the format:</p>
  
  <pre><code>user = csj483
  database = cs495z_csj483
  password = fjlID9dD923
  </code></pre>
  
  <p>Here is the code I am trying to run from the makefile, but it is not working. If I run the same code directly in the shell, it seems to work ok. Note that I had to use double $$s because make doesn't like single ones.</p>
  
  <pre><code>login:
      for line in $$(cat /u/z/users/cs327e/$$USER/.zinfo); \
      do \
          PASSWORD=$$line; \
          echo $$PASSWORD; \
      done 
      echo $$PASSWORD
  </code></pre>
  
  <p>At this point, I am just trying to get the password, which should be the last value that PASSWORD is set to in the loop. If anyone can suggest an easier way to retrieve the password, or point out my error in my code, I would appreciate it. Eventually I will also want to retrieve the database name as well, and any help with that too would be appreciated as well. I am new to bash, but experienced in numerous other languages.</p>
