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)
do this
``
``
if (condition)
do this
else
do that
``
