Hi Wiiliam, |
| 21 |
|
| 22 |
this is a convenient 'abbreviation' or 'alias' for cobnstructs such this one |
| 23 |
|
| 24 |
if [ foo ] |
| 25 |
then |
| 26 |
bar |
| 27 |
fi |
| 28 |
|
| 29 |
in shell scripting. |
| 30 |
|
| 31 |
Most shells have implemented this as a builtin (and 'test' also) |
| 32 |
though. |
| 33 |
|
| 34 |
HTH! |
| 35 |
|
| 36 |
Best regards, |
