## Tests the env command in various scenarios: without arguments, setting, unsetting, and mixing envrionment variables.
# FIXME: All of these tests are broken and will not even call FileCheck.

## Check default environment.
# RUN: env | FileCheck -check-prefix=NO-ARGS %s
#
# NO-ARGS: BAR=2
# NO-ARGS: FOO=1
# NO-ARGS: QUX=3

## Set environment variables.
# RUN: env FOO=2 BAR=1 | FileCheck -check-prefix=SET-VAL %s
#
# SET-VAL: BAR=1
# SET-VAL: FOO=2
# SET-VAL: QUX=3

## Unset environment variables.
# RUN: env -u FOO -u BAR | FileCheck -check-prefix=UNSET-U %s
#
# UNSET-U-NOT: BAR
# UNSET-U-NOT: FOO
# UNSET-U: QUX=3

## Mixed set and unset environment variables.
# RUN: env -u FOO BAR=1 -u BAR FOO=2 | FileCheck -check-prefix=MIXED-SET-UNSET %s
#
# MIXED-SET-UNSET-NOT: BAR
# MIXED-SET-UNSET: FOO=2
# MIXED-SET-UNSET: QUX=3

## Mixed set and unset with additional variable.
# RUN: env -u FOO BAR=1 -u BAR FOO=2 BAZ=4 | FileCheck -check-prefix=MIXED-SET-UNSET-ADD-3 %s
#
# MIXED-SET-UNSET-ADD-NOT: BAR
# MIXED-SET-UNSET-ADD: BAZ=4
# MIXED-SET-UNSET-ADD: FOO=2
# MIXED-SET-UNSET-ADD: QUX=3
