OPENGREP_FORCE_COLOR

Also spelled

SEMGREP_FORCE_COLOR

Value

true, yes, 1 or false, no, 0

Equivalent to

--force-color

See also

NO_COLOR

Read when neither --force-color nor --no-force-color is given. A true value styles the output even when it goes to a pipe or a file, and takes precedence over NO_COLOR. A false value keeps the default, in which only output to a terminal is styled.

The accepted values are true, yes and 1 for true, and false, no and 0 for false. Any other value is rejected like an invalid flag value, with exit status 2.

## Examples

### Color through a pipe, from the environment
