- NAME
- env - run a program in a modified environment
-
- SYNOPSIS
- env [-] [-i] [-u name] [+ignore-environment] [+unset=name]
- [name=value]... [command [args...]]
-
- DESCRIPTION
- This manual page documents the GNU version of env. env runs
- a command with an environment modified as specified by the
- command line arguments. Arguments of the form
- `variable=value' set the environment variable _✓v_✓a_✓r_✓i_✓a_✓b_✓l_✓e to
- value _✓v_✓a_✓l_✓u_✓e. _✓v_✓a_✓l_✓u_✓e may be empty (`variable='). Setting a
- variable to an empty value is different from unsetting it.
-
- The first remaining argument specifies a program to invoke;
- it is searched for according to the specification of the
- PATH environment variable. Any arguments following that are
- passed as arguments to that program.
-
- If no command name is specified following the environment
- specifications, the resulting environment is printed. This
- is like specifying a command name of `printenv'.
