When working in terminal, I’d like my prompt to look like:[user@host:.../cocoa/apple/examples]$I like to know a couple levels above where I am without it taking over the entire screen width. This function will let you show the last 3 levels or the whole path if less. It also shows ~ for your home path. Here is the code to get this to work in your .profile/.bashrc/whatever:

# Prompt that replace console title and uses breadcrumbsexport PS1='\[\e]2;\u@\H \w\a\][\u@\h:`breadcrumbs "$PWD" 3`]\$ ‘# Function that returns the last n path components of the specified path after# replacing $HOME with ~.  Call like:#     breadcrumbs path nfunction breadcrumbs{    echo $1 | sed “s|^$HOME|~|” | awk -v n=$2 ‘{        # Split the path into components        count = split($0, components, “/”);        # If there are less than n components, just print the whole path        if (count <= n) {            print $0        } else {            # Else print the last n components            if (count > n) {            	printf “…/”            }            for (i = count - n + 1; i < count; i++) {                printf “%s/”, components[i]            }            printf “%s”, components[i]        }    }’}
