- env - set environment for command invocation
- env [ options ] [name=value]... [command ...]
- env modifies the current environment according to the name=value arguments, and then
invokes command with the modified environment.
- If command is not specified, the resulting environment is written to standard output quoted as required for
reading by the sh.
- -i, --ignore-environment
- Invoke command with the exact environment specified by the name
=value arguments; inherited environment variables are ignored. As an obsolete feature, - by
itself can be specified instead of -i.
- -p, --portable
- Quote the values as necessary to be able to be interpretted correctly by the shell.
- -u, --unset=name
- Unset the environment variable name if it was in the environment.
This option can be repeated to unset additional variables.
- If command is invoked, the exit status of env will be that of command. Otherwise, it will be
one of the following:
- env completed successfully.
- command was found but could not be invoked.
- command could not be found.
- sh(1), export(1)
