# Quote marks
|

|

|
## Single-quotes (aka _strong_ quotes)
|
||
|
|
|
||
|
|
Bash will interpret everything in the string as a literal:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
echo 'The directory is $(pwd)'
|
||
|
|
# The directory is $(pwd)
|
||
|
|
```
|
||
|
|
|
||
|
|
## Double-quotes
|
||
|
|
|
||
|
|
Bash will interpret strings as strings but will interpret expansions and substitutions as executable processes:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$pointlessVar='directory'
|
||
|
|
|
||
|
|
echo "The ${pointlessVar}"
|
||
|
|
|
||
|
|
# The directory is /home/thomas
|
||
|
|
```
|
||
|
|
|
||
|
|
It is therefore generally best to use double quotes whenever we wish to return mixed values.
