# /bin/rbash
# /bin/dash

To change your shell.

Installation

On the HOME dir, like /home/wpsze/

1

4
git clone https://github.com/ohmybash/oh-my-bash.git
mv oh-my-bash-master .oh-my-bash
cd .oh-my-bash/
chmod +x oh-my-bash.sh

Backup our .bashrc first, 

1
cp ~/.bashrc ~/.bashrc.bak

copy the oh-my-bash to .bashrc 

1
cp ~/.oh-my-bash/templates/bashrc.osh-template ~/.bashrc

source it, 

1
source ~/.bashrc

The installation and use of oh-my-bash is very simple, and the use of oh-my-bash is similar to that of oh-my-zsh. There are functions such as auto-completion (ignoring case), history, and quick cd.

Theme

ls .oh-my-bash/themes/
vim ~/.bashrc
#
# OSH_THEME="font"
# or
OSH_THEME="simple"

and change theme like /home/wpsze/.oh-my-bash/themes/font/font.theme.sh 

1

CLOCK_THEME_PROMPT_PREFIX='['
CLOCK_THEME_PROMPT_SUFFIX=']'

local hostname="${_omb_prompt_bold_green}\u@\h"

absolute path

How can I display the absolute path in bash prompt? https://superuser.com/questions/202212/how-can-i-display-the-absolute-path-in-bash-prompt

# PS1='\u@\h:\w\$ '
# Replace the "\w" with "\$PWD"
# PS1=[\u@\h ]\$PWD$
PS1="$(clock_prompt)$python_venv${hostname}:${_omb_prompt_bold_teal}\${PWD} $(scm_prompt_char_info)${ret_status}$ ${_omb_prompt_normal}"

The key here is * gives the full path while * gives only the directory.

conda initialize

Add the following into .bashrc

if [ $? -eq 0 ]; then
    eval "$__conda_setup"

    if [ -f "/home/wpsze/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/wpsze/anaconda3/etc/profile.d/conda.sh"

History of most recent directories

Looks like a history of most recent directories you've been in. which d identifies it as an alias to dirs shell builtin, which prints the contents of the directory stack. Just tried it and number keys allow to move to respective directory.

dirs command shell builtin is used to display the list of currently remembered directories. By default, it includes the directory you are currently in. A directory can get into the list via pushd command followed by the dir name and can be removed via popd command.

$ dirs -v | head -n 10
# 0 ~
# 1 ~/.oh-my-bash/themes/font
# 2 ~/.oh-my-bash/themes
# ...

## Select number above will jump to that direcotry
$ 1
.oh-my-bash/themes/font $

add it to .bashrc

refer to zsh directories.zsh here dl() function name can be defined by yourself. 

1

3
function dl() {
    dirs -v | head -n 10
}
Remark: In .oh-my-bash/lib/directories.sh New package may be false on this function as 
1
OMB_DIRECTORIES_CD_USE_PUSHD=true #false
Set as ture

If it is client's node and don't want to modify the terminal config, then just add a function on .bashrc,
