fuck() {
    sudo $(fc -ln -1)
}

This function takes the last command and puts sudo in front of it. Actually used it in a zoom call at work without thinking and it took a second to realize why everyone was laughing. Not my invention--came across it years ago on stackoverflow or someplace and thought it was funny/useful.

kmirl@tux:~$ ls /root
ls: cannot open directory '/root': Permission denied
kmirl@tux:~$ fuck
[sudo] password for kmirl: 
bin  debs  docs  Mail

Isn't this the same effect as just running 'sudo !!' ?

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)

Yeah but instead of a function you just make it an alias.

[-] subtext@lemmy.world 1 points 3 months ago

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
