- User Variables -
|
| 10 |
Variables must always be enclosed by {}
|
| 11 |
e.g. ${foo} ${bar}
|
| 12 |
- Internal Shell Variables -
|
| 13 |
Do not use {} with internal variables unless appropriate
|
| 14 |
e.g. case $1 in
|
| 15 |
e.g. foo=$IFS
|
| 16 |
e.g. echo "blah${1}123"
|
| 17 |
- Assigning with Quotes -
|
| 18 |
When assigning to a variable from another variable, you should
|
| 19 |
not need quotes. However, you do when assigning from a subshell.
|
| 20 |
e.g. foo=${bar}
|
| 21 |
e.g. foo="$(uname -a)"

- Brackets -
|
| 27 |
Always use the [ ... ] form instead of [[ ... ]] as the later only really
|
| 28 |
works in bash, and we should support as many shells as we can.
|
| 29 |
- Quoting -
|
| 30 |
When dealing with strings, you should quote both sides.

- Structure -
|
| 36 |
Use the more compact form
|
| 37 |
e.g. if ... ; then
|
| 38 |
e.g. while ... ; do
|
| 39 |
Do not use the older form
|
| 40 |
e.g. if ...
|
| 41 |
then
|
| 42 |
- Functions -
|
| 43 |
Use the more compact form
|
| 44 |
e.g. foo() {
|
| 45 |
Do not lead with 'function '
|
| 46 |
e.g. function foo() {
|
