RENV(1)

NAME
renv - normalize environment variables

SYNOPSIS
renv file ... [-q]
renv name="value" [file]

DESCRIPTION
Filter environment variables in a format suitable for sh(1). Only lines defining variable names using the characters [_a-zA-Z0-9] with a value in double-quotes are emitted. Values may also be empty.

    A="one"
    B="two"
    D=""

If the first argument is in the format ‘name=value’ renv will store and environment for reference in subsequent labels. By default entries are appended to $SD/local.env.

Optional arguments are as follows:

-q  Validate only, do not print lines.

LITERALS
Escape sequences starting with ‘\’, or subshells using ‘$(...)’ are not permitted.

‘$$’ expands to a single dollar sign.

EXAMPLES
Print environment variables in a normalized format

    $ renv final.env

Save the status code of the last command

    $ renv LAST_EXITSTATUS="$?"

CAVEATS
Tabs and multiple spaces are converted to into a single space. There is no provision for embedding literal double-quotes.

renv must be found in the current working directory or in the path defined by SD.
