|

|
||||
For shell scripts specifically (not exhaustive):
|
||||
|
||||
- We use tabs for indentation.
|
||||
|
||||
- Case arms are indented at the same depth as case and esac lines.
|
||||
|
||||
- We prefer $( ... ) for command substitution; unlike ``, it
|
||||
properly nests. It should have been the way Bourne spelled
|
||||
it from day one, but unfortunately isn't.
