| ## Tests the behaviour of chaining env commands together. |
| |
| ## Check that internal env can call internal env. |
| # RUN: env env | FileCheck -check-prefix=CHECK-2-EMPTY-ARGS %s |
| # |
| # CHECK-2-EMPTY-ARGS: BAR = 2 |
| # CHECK-2-EMPTY-ARGS: FOO = 1 |
| |
| ## Check setting variables in a nested env call. |
| # RUN: env FOO=2 env BAR=1 | FileCheck -check-prefix=CHECK-2-VAL %s |
| # |
| # CHECK-2-VAL: BAR = 1 |
| # CHECK-2-VAL: FOO = 2 |
| |
| ## Check unsetting variables in a nested env call. |
| # RUN: env -u FOO env -u BAR | FileCheck -check-prefix=CHECK-2-U %s |
| # |
| # CHECK-2-U-NOT: BAR |
| # CHECK-2-U-NOT: FOO |
| |
| ## Check mixed setting and unsetting in nested env calls. |
| # RUN: env -u FOO BAR=1 env -u BAR FOO=2 | FileCheck -check-prefix=CHECK-2-U-VAL %s |
| # |
| # CHECK-2-U-VAL-NOT: BAR |
| # CHECK-2-U-VAL: FOO = 2 |
| |
| ## Check setting, unsetting, and adding a new variable in nested env calls. |
| # RUN: env -u FOO BAR=1 env -u BAR FOO=2 env BAZ=3 | FileCheck -check-prefix=CHECK-3 %s |
| # |
| # CHECK-3-NOT: BAR |
| # CHECK-3: BAZ = 3 |
| # CHECK-3: FOO = 2 |
