Reuse command to connect in bash

Question

I am using the following to indent the output of the configure script:

./configure | sed "s/^/    /"

Now I want to reuse part by pipe, so I don't have to write

./configure | sed "s/^/    /"
make | sed "s/^/    /"
make install | sed "s/^/    /"

I tried to put sed

in a variable like this:

indent=sed "s/^/    /"

and then do

./configure | indent

but it didn't work - how can i achieve this?

Try the following:

(./configure; make; make install) | sed "s/^/    /"

Why not just make a nickname?

alias indent="sed 's/^/    /'"

Use a BASH array to store the sed command:

indent=(sed "s/^/    /")

Then use:

./configure | "${indent[@]}"
make | "${indent[@]}"
make install | "${indent[@]}"

OR otherwise use the function for this sed command:

indent() { sed "s/^/    /"; }

Then use:

./configure | indent
make | indent
make install | indent
