## 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
