+Here are my **personal** coding standards for some languages.
+
+## Interpreted languages
+#### Never put the file extension to the source file instead use a shebang.
+`` 
+    #!/bin/sh
+    #!/bin/python3
+    #!/bin/perl
+``
+
+## Posix shell
+#### Always wrap variables with `"${}"` to prevent globbing.
+`` 
+    echo "${var}"
+    echo "${1}"
+    echo "${@}"
+``
+
+## Makefiles
+#### If Makefile is fully posix complient and doesn't have anything extra add 
+`.POSIX:` to the beginning of the file
+
+## C 
+#### Use K&R style `if`s
+``
+    if (condition) {
+        do this;
+        do that;
+        do another;
+    }
+``
+#### if only one line don't use curly braces.
+``
+    while (condition)
