How can I check all the different shells that I can use in OSX Terminal application?
The default one is bash, and I know zsh because I tried and it worked. I wonder how can I check if there are any more than this two.
The easy way is go to /etc and check the shells file. The content is the list of shells available in Mac OSX.
The included by default are:
/bin/bash
/bin/csh
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh
Alternatively, you can check their binaries by going to /bin and recognising them visually. Naturally, you have to know them in order to recognise them.
In MacOS the following command will list the available shells on your system
$ ls -l /bin/*sh
-r-xr-xr-x 1 root wheel 618448 Nov 19 00:26 /bin/bash
-rwxr-xr-x 1 root wheel 380016 Feb 7 16:11 /bin/csh
-r-xr-xr-x 1 root wheel 1287040 Sep 21 00:35 /bin/ksh
-r-xr-xr-x 1 root wheel 618512 Nov 19 00:26 /bin/sh
-rwxr-xr-x 1 root wheel 380016 Feb 7 16:11 /bin/tcsh
-rwxr-xr-x 1 root wheel 610288 Sep 21 00:35 /bin/zsh

I have a .profile which is copied to /home/vscode during my container build before running common-debian.sh
This is important as during container image build common-delian.sh will skip creating a default .profile if the file is already present
In that profile I have a number of bash functions and some exported variables.
One of the variables relies on executing one of the declared functions, and in my shell I can see the correct variable and value is set.
This problem arises when opening a new integrated terminal in vscode.
"new terminal" command
However none of my functions are available in the shell to execute.
Confirmed through typeset -F
I can run source ~/.profile and the functions are then available in the shell.
Is there some place I can turn up logging to determine what is happening here?
Details about the install
vscode Host install is Mac M1
VERSION='0.202.6'
CONTENTS_URL='https://github.com/microsoft/vscode-dev-containers/tree/main/containers/debian/history/0.202.6.md'
DEFINITION_ID='debian'
VARIANT='bullseye'
GIT_REPOSITORY='https://github.com/microsoft/vscode-dev-containers/'
GIT_REPOSITORY_RELEASE='v0.224.0'
BUILD_TIMESTAMP='Fri, 25 Feb 2022 10:48:36 GMT'
Example function declaration
kconfig() {
ls $HOME/.kube/configs/* | tr '\n' ':'
}
declare -f kconfig
Example variable making use
export KUBECONFIG="$(kconfig)"
I can confirm before sourcing .profile, this variable is set and valid and should only have come from the .profile declaration.

Edit below:
Now I am copying this file in as ~/.bash_profile
There is still a .profile, vscode common-debian.sh creates this if the file is not present when building the container image.

also added the following to /etc/profile.d/
# This file is intended to be copied into /etc/profile.d
project_profile="$HOME/.bash_profile"
if [ -r $project_profile ]; then
source $project_profile
else
echo "File not found or not readable: $project_profile"
fi
none of which has had an effect on the resulting new shells
perhaps ignoring vscode
docker exec -it {container} /bin/bash still has the same results.
I have also tried creating an empty terminal profile with an empty shell profile, launching vscode from that terminal window.
Thinking that perhaps inherited env was causing issues.
Also set the following user setting
"terminal.integrated.inheritEnv": false,
From the man page for bash (in the INVOCATION section):
When bash is started non-interactively, to run a shell script, for
example, it looks for the variable BASH_ENV in the environment, expands
its value if it appears there, and uses the expanded value as the name
of a file to read and execute. Bash behaves as if the following command
were executed:
if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
but the value of the PATH variable is not used to search for the filename.
In your use case, i.e. a shell script, no startup file is read. But you can change that by setting the value of BASH_ENV to a file you want to read on startup. Alternately your script can source anything you like when it runs, e.g. source .profile.
Extracted from answer comments:
Original Poster noted that the issue was fixed using this in vscode:
"terminal.integrated.defaultProfile.linux": "bash",
"terminal.integrated.profiles.linux": {
"bash": {
"path": "/bin/bash",
"icon": "terminal-bash",
"args": [ "-l" ]
},
}
(The -l arg to make it a login shell being, probably, the important part?)
I think I messed up my .bash_profile and .bashrc file.
Is there any way I can reset them to default?
When I want to access them through the terminal I get: Permission denied.
If I open them using sublime text, my .bashrc is completely empty and my .bash_profile contains the following code:
PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
export PATH=/usr/local/bin:$PATH
alias python=python3
alias sublime="open -a /Applications/Sublime\ Text.app"
source ~/.profile
Any idea on what I could add/delete to any of the files?
Python does not run properly anymore since I accidentally played around on those files.
You may find the default .bash_profile and .bashrc files in /etc/skel/
[user#server /]$ ls -la /etc/skel

If it's the case you can get them back:
cp /etc/skel/.bash_profile /etc/skel/.bashrc ~/
Make a backup of your current files before ;)
Just to explain: the content of /etc/skel/ is copied into the home directory of a user when created with adduser.
I want to set an alias for vim so that when I use vim I want all my personal vim files to be sourced. (I want to do this because the machine I use is used by everyone else, so I don't want to affect others' usage. The alias is also set only when I login into the machine)
alias vim='vim -c "source ~/.dc_dotfiles/.vimrc_dc" --cmd "set rtp+=~/.dc_dotfiles/.vim"'
But this is not working as files in ~/.dc_dotfiles/.vim are not being sourced.
Here are the contents of ~/.dc_dotfiles/.vim folder
~$ ls -lhart .dc_dotfiles/.vim/plugin/

drwxr-xr-x 2 veveo veveo 24 Oct 18 17:35 .
When I am using the screen I set a flag that will let know if I am logged in. I added this part to my ~/.vimrc
if !empty($DCSCREENFLAG)
set rtp+=~/.dc_dotfiles/.vim
endif
If the flag is set, it means that I am logged in and using the screen, so go ahead and add the directory to the runtimepath.
I've been toying with chef, and may have installed ruby along the way. Now I would like to upgrade to ruby 2.0. Anyhow I'm curious what could have caused ruby to be added to the path of all new users? Note: there's no mention of ruby in the new user's .bashrc, .profile, or in the global /etc/environment:
ubuntu#ip-10-10-10-10:~$ sudo useradd -m testuser

/opt/rubies/1.9.3-p429/bin/ruby
testuser#ip-10-10-10-10:~$
I'm at a loss as to where to look to find and remove the references to ruby 1.9.3 being added apparently automatically.
I faced similar issue. Please try with this option dpkg --get-selections.
As you might be knowing everything is considered as gems. Hence try with this also if above does not work...
$ gem -h
or
$rvm list known
and then you can install only the required version using
rvm install ruby 2.0.0-p247

Turns out somewhere along the way, somehow, chruby got installed. The quick fix to resolve the user PATH not being overwritten was to disable the .sh chruby put in /etc/profile.d:

Better would be to uninstall chruby, but it's not obvious to me how to do that given I don't know / don't remember how it was installed.
I simply changed the name in finder and now when I use a command in terminal, this is the error I keep receiving. I've tried to look at all the other cases of the same error but they all pertain to different solutions that don't work. The path is clearly correct because when I try to cd into the directory, I'm already in the directory it is contained in.

type cd ap and then [Press Tab] to autocomplete, may be there is some spaces after app
On MacOS with the default Bash
$ bash --version

cd app raises the error
-bash: cd: app: No such file or directory
due to a bug of the super old Bash version installed with MacOS.
The workaround is to prefix the directory with ./ in this way
cd ./app
and it will work.
The alternative is to install a modern and better Bash version using Homebrew.
brew install bash
