📋 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 variables, or if it cannot run child. Otherwise its exit code is the same as that of child.
