Question

`xargs` provides a really nice mechanism to pipe results into successive `pants` calls Is there a similar pattern for joining results of two `pants` calls My use case is pretty non standard but I would like to run something like `pants lt find a buch of targets gt amp amp pants lt find a bunch of different targets gt | xargs pants test`

Just use command substitution is one way `pants test $ $ `

The specific things I want to join are unit tests that are 3 dependee layers away from resource file targets unit tests that are 2 dependee layers away from python source targets

Lots of ways

high-yak-85899 · Answer

Command substitution is similar to what I had come up with so sounds like that s the way to keep going

Maybe just group the way your doing a subshell ` amp amp | pants test`

Knowing thy shell was deemed important and boy were they right
