how to compare list of functions from 2 files?
I wanted to list all functions in 2 files I have, so I used:
cat <file_A> | grep -E "^function"
cat <file_B> | grep -E "^function"
How can I compare the outputs and highlight the similarities?
bash grep

Two options here:
if you need GUI solution - then you can use Meld Merge tool:
sudo apt install meld
meld <(grep -E "^function" file_A) <(grep -E "^function" file_B)
if you need terminal solution - use power of diff:
diff <(grep -E "^function" file_A) <(grep -E "^function" file_B)
no way of doing so without saving output to files?

You can use the process substitution functionality in this way:
diff <(cat <file_A> | grep -E "^function") <(cat <file_B> | grep -E "^function")
You do not need to use cat
in this case. Also, there is a nice wrapper of diff
called colordiff
(it must be installed: sudo apt install colordiff
). Here is one of my favorite usages:
colordiff --side-by-side --left-column --width=180 --show-C-function <(grep -E "^function" <file_A>) <(grep -E "^function" <file_B>)
