Just try it out ... |
| 12 |
|
| 13 |
WORKDIR="SOME WORK DIR" |
| 14 |
S=${WORKDIR}/SUBDIR |
| 15 |
echo ${S} |
| 16 |
|
| 17 |
Output: SOME WORK DIR/SUBDIR |
| 18 |
|
| 19 |
... and you will see that this works. |
| 20 |
|
| 21 |
Although on the other hand you can't do ... |
| 22 |
|
| 23 |
S=SOME WORK DIR/SUBDIR |
| 24 |
echo ${S} |
| 25 |
|
| 26 |
Output: -bash: WORK: command not found |
| 27 |
|
| 28 |
... or ... |
| 29 |
|
| 30 |
S=${WORKDIR}/SUB DIR |
| 31 |
echo ${S} |
| 32 |
|
| 33 |
Output: -bash: DIR: command not found |
| 34 |
|
| 35 |
... as then things end up breaking as they are seen as commands. |
| 36 |
|
| 37 |
It's up to you whether you use them or not; while "..." helps you spare |
| 38 |
out on characters in some cases, in other cases not having them |
| 39 |
requires you to define an extra variable. Depends on what you prefer... |
