What Others Think

If you're doing something like this: "rm -Rf ../$blah/", you have to make sure that $blah is set, or at least give it a default value like ${blah:-DEFAULTVALUE} and quote it. You need to quote $PWD also. Imagine that $PWD is unset or has a space in it in this scenario. "basename $PWD" fails and $blah remains unset. The next command becomes "rm -Rf ..//", which could be disasterous if you're one level up from the root directory.

Thank you eightmillion. Can you find any problems with this revision?

removedir () { echo "You are about to delete the current directory $PWD Are you sure?"; read human; if [[ "$human" = "yes" ]]; then blah=$(echo "$PWD" | sed 's/ /\\ /g'); foo=$(basename "$blah"); rm -Rf ../$foo/ && cd ..; else echo "I'm watching you" | pv -qL 10; fi; }

That is a bit better, although you don't need to mess with the sed business and you still need to quote your variable when you call "rm -Rf" or you could end up deleting multiple unintended directories. This is pretty workable:

removedir(){ read -p "You are about to delete the current directory $PWD Are you sure? " human;if [ "$human" = "yes" ]; then foo=$(basename "$PWD");[ -z "$foo" ] && { echo "Error: Couldn't get working directory" >&2;return 1;}; rm -Rf ../"$foo"/ && cd ..; else echo "I'm watching you" | pv -qL 10; fi; }

Notice the "[ -z $foo ]" part. That checks if the variable $foo is null. If it is null, then the function echoes an error message to stderr and returns a non-zero exit status. Otherwise, it continues. Also notice "read -p". You can specify a prompt for the read command. On a side note, a neat way to get the basename of the current working directory in Bash is to use "${PWD##*/}".
