According to this super user question, someone said that !! won’t work in a function, so you must use the fc -ln -1 command in a subshell instead. Note the response that says eval shouldn’t be used (not sure why)
Eval shouldn’t be used on userinput. Meaning that if smb other than you may use this to change the system he could put malicious code in the eval part.
Isn’t this the same effect as just running ‘sudo !!’ ?

Oh good point, I didn’t think about that

Probably doesn’t matter on shell level
no because it takes the previous command and adds sudo to it right?
!!is a shortcut for whatever the last command wasis it not?E: https://devhints.io/bash#history
