We all look like hackers when using the terminal (specially if we have green over black theme) but the truth is we tend to be amazingly lazy, and start using poor techniques.
I'm very untidy on my life, and I'm used to save the git clones in brand new directories so for example, in order to enter in my cloned repo, I have to...
# cd random_named_dir
# cd cloned_repo_dir
or even worse:
#cd random_nam*
#cd *
When updating my git, (I'm sorry, probably my virtual infrastructures' teacher will read this) in hurry I might write:
git add .
I sometimes save stuff in $HOME but later I don't remember where did I put 'em, or complain and sigh when I have to write my password in sudo because a long time passed since the last time I wrote it.
What are your most dark lazy secrets on the terminal? Do you want to change that and start using the terminal properly even in hurry? :p
