## NAME
       envdir - runs another program with environment modified according to files in a specified di‐
       rectory.

## SYNOPSIS
       **envdir** _d_ _child_

## DESCRIPTION
       _d_ is a single argument.  _child_ consists of one or more arguments.

       **envdir** sets various environment variables as specified by files in the directory named _d_.  It
       then runs _child_.

       If  _d_  contains  a file named _s_ whose first line is _t_, **envdir** removes an environment variable
       named _s_ if one exists, and then adds an environment variable named _s_ with value _t_.  The  name
       _s_  must not contain =. Spaces and tabs at the end of _t_ are removed. Nulls in _t_ are changed to
       newlines in the environment variable.

       If the file _s_ is completely empty (0 bytes long),  **envdir**  removes  an  environment  variable
       named _s_ if one exists, without adding a new variable.

## EXIT CODES
       **envdir**  exits 111 if it has trouble reading _d_, if it runs out of memory for environment vari‐
       ables, or if it cannot run _child_.  Otherwise its exit code is the same as that of _child_.
