If you don't use other LC_{category}, there is no difference. |
| 9 |
|
| 10 |
But if you use it with these variables, there it is: |
| 11 |
|
| 12 |
LANG is fallback, overridden by all other LC_* variables. |
| 13 |
|
| 14 |
LC_ALL is enforcement, and overrides LANG and all LC_{category} |
| 15 |
variables. It means: if you define LC_ALL, sessing LC_{category} has no |
| 16 |
effect. |
| 17 |
|
| 18 |
There is an example: |
| 19 |
|
| 20 |
utx$ ( export LANG=C LC_NUMERIC=C LC_ALL=C ; printf "%'5.3f\\n" 1 ) |
| 21 |
1.000 |
| 22 |
utx$ ( export LANG=C LC_NUMERIC=C LC_ALL=cs_CZ ; printf "%'5.3f\\n" 1 ) |
| 23 |
1,000 |
| 24 |
utx$ ( export LANG=cs_CZ LC_NUMERIC=C LC_ALL=C ; printf "%'5.3f\\n" 1 ) |
| 25 |
1.000 |
| 26 |
utx$ ( export LANG=C LC_NUMERIC=cs_CZ LC_ALL=C ; printf "%'5.3f\\n" 1 ) |
| 27 |
1.000 |
| 28 |
utx$ ( export LANG=C LC_NUMERIC=cs_CZ ; printf "%'5.3f\\n" 1 ) |
| 29 |
1,000 |
| 30 |
|
| 31 |
Note: Script programmers do often a mistake, using following |
| 32 |
construction: |
| 33 |
LC_TIME=C date |
| 34 |
|
| 35 |
It works incorrectly, if you have LC_ALL set to any language. |
