Getting the old Terminal back after uninstalling fish

bashcommand lineterminal

Recently I got tired of the smaller kinks that the Fish Shell presented me with (undiscoverable commands etc.) so I decided I wanted to change the shell back to normal and uninstall fish.

However in the process of doing so I have done something terribly wrong.

I have set it to the normal: /bin/bash

However Im represented with a series of prompts (in regards to Vagrant) and have to exit this with the CTRL+C command (cancel)

I want to get my old terminal back (with my current folder prepended etc.) but I have no clue in how to accomplish this.

I've attached two screenshots. One is the current terminal (the one with the bash -bash-3.2$in front.
The second is the terminal i want (the default with username appended) [source of image is found on the internet, for reference]

This is the terminal I have

This is the terminal I want

I've found two things:

My bash profile is deleted hence i cannot see my computer name etc. I've tried to recreate it but:
I need a sample .bash_profile
…and i need it to be persistent such that when i exit my terminal I do not fire the VVV script (that it apparently fires off when it first enters the terminal)

First, rm ~/.bashrc ~/.bash_profile ~/.profile These are not needed and don't exist by default.

Second, check to see /etc/profile is there, should be:

# System-wide .profile for sh(1)
if [ -x /usr/libexec/path_helper ]; then
    eval `/usr/libexec/path_helper -s`
fi
if [ "${BASH-no}" != "no" ]; then
    [ -r /etc/bashrc ] && . /etc/bashrc
fi

Third, check /etc/bashrc (this is where your prompt is defined). Should be:

# System-wide .bashrc file for interactive bash(1) shells.
if [ -z "$PS1" ]; then
   return
fi
PS1='\h:\W \u\$ '
# Make bash check its window size after a process completes
shopt -s checkwinsize
# Tell the terminal about the working directory at each prompt.
if [ "$TERM_PROGRAM" == "Apple_Terminal" ] && [ -z "$INSIDE_EMACS" ]; then
    update_terminal_cwd() {
        # Identify the directory using a "file:" scheme URL,
        # including the host name to disambiguate local vs.
        # remote connections. Percent-escape spaces.
    local SEARCH=' '
    local REPLACE='%20'
    local PWD_URL="file://$HOSTNAME${PWD//$SEARCH/$REPLACE}"
    printf '\e]7;%s\a' "$PWD_URL"
    }
    PROMPT_COMMAND="update_terminal_cwd; $PROMPT_COMMAND"
fi

Finally, if it's still not working make sure you have /bin/bash set as your default shell using the advanced options in the User & Groups System Preference. If you don't login with bash, it will bypass the configs in /etc/

MacOS – Terminal – how to restart session after inadvertently exiting

At this point, there's no way to get the tab back. The terminal session is closed, and it no longer has a TTY. There's just no way to reference the tab in order to do anything clever. I'd suggest adding this function to your .bashrc or .profile so that you won't have the issue in the future:

exit() {
    read -t5 -n1 -p "Do you really wish to exit? [yN] " should_exit || should_exit=y
    case $should_exit in
        [Yy] ) builtin exit $1 ;;
        * ) printf "\n" ;;
    esac
}

or, for those of us who use the Z Shell (add it to your .zshrc):

exit() {
    if read -t5 -q "?Do you really wish to exit? [yN] "; then
        builtin exit $1
    fi
}

It's a nice little barrier between you and that annoying exit command! Lord knows I've done the same thing many times in the past.

“bash” command runs scripts in version 3.2, not 4.4

The error here is that the first path in PATH was to the bash executable, instead of to the directory that contains the bash executable. For readers with similar problems: double check to make sure any path you're adding to your PATH variable resolves to a directory, not to a file.

Problem:

I had added the following to my .bash_profile:

PATH=/usr/local/bin/bash:$PATH

/usr/local/bin/bash is not a directory. It's a file (well, a symbolic link to a file). So, regardless of placing it at the very beginning of PATH, the command bash will not find an executable file named bash inside any directory in PATH until it gets to /bin.

Solution:

In .bash_profile, setting

PATH=/usr/local/bin:$PATH

Solves the problem. Now the command bash finds the executable inside /usr/local/bin before it gets to /bin.
