Quoting
Quoting can be used for three purposes in the shell:
- to group a sequence of words into a single "word"
- to control the kinds of transformations that are performed
- to capture the output of commands (back-quotes)
The three different kinds of quotes have three different effects:
single-quote (') |
| grouping, turns off all transformations |
double-quote (") |
| grouping, no transformations except $ and ` |
backquote (`) |
| no grouping, capture command results |
