  • [gentoo-user] wiki page(kernel/upgrade) command confusion: 'cat' and 'a

    From russian sky@21:1/5 to All on Fri Jan 14 11:10:01 2022
    the sentence is just as follows:

    diff <(cat .config | sort) <(cat .config.old | sort) | awk '/^>.*(=|Linux)/ { $1=""; print }'

    without inserting the 'cat' and '*'(the part of awk),It seems like, the result of the command is the same as before.


    Does the existence of the aboving 'cat' and '*' (the part of awk) have some special meaning which make them necessary on the sentence?
