This question already has an answer here:
In bash, I use arguments that look like
paste <(cat file1 | sort) <(cat file2 | sort)
comm <(cat file1 | sort) <(cat file2 | sort)
When I check
man comm or
man paste, the documentation says the args are indeed FILES.
Are intermediate temporary files get created (on TEMP filesystem or elsewhere on slower disk) for
<(cat file1 | sort)and
<(cat file2 | sort)?
What is the name for this
<( )magic? (to lookup its documentation)
Is it specific to bash or does it work across other shells?
