According to this super user question, someone said that
!!won’t work in a function, so you must use thefc -ln -1command in a subshell instead. Note the response that saysevalshouldn’t be used (not sure why)Yeah but instead of a function you just make it an alias.
Oh good point, I didn’t think about that
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.
Probably doesn't matter on shell level
