env-replace

Pipe commands that produce lots of output through env-replace to replace expanded environment variables (especially prefix paths in build output) with the environment variables themselves.

Install:

python3 -m pip install env-replace

Usage:

export PREFIX="/super-long-prefix-path"
echo "cc -I$PREFIX/include -L$PREFIX/lib ..." | env-replace

reverses environment variable expansion so that the output is:

cc -I$PREFIX/include -L$PREFIX/lib ...

instead of

cc -I/super-long-prefix-path/include -L/super-long-prefix-path/lib ...
