Repeat last executed command

I don't know why this ain't written as simply as it is. I always see it's just used as parameter, like: vi `!!` But i use it to repeat a command, as i always work on several shells and check the result of one shell on a second.

Generate Random Passwords

If you want a password length longer than 6, changing the -c6 to read -c8 will give you 8 random characters instead of 6. To end up with a line-feed, use this with echo: # echo `< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c6` Modern systems need higher strenght, so add some special characters: # < /dev/urandom tr -dc '12345!@#$%qwertQWERTasdfgASDFGzxcvbZXCVB' | head -c8
This is sample output - yours may be different.

< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c6
