I'm trying to run source /Users/alastair/.rvm/scripts/rvm, but keep getting:
Bad : modifier in $ (").
Where would the problem be? Happy to paste other files in if these would help.
Are you in any case running a shell that is not Bash or ZSH? Bash >= 3.2.25 or ZSH >= 4.3.10 is required.
Your problem looks like you were using minimalistic shell sh which is not supported by RVM.
You can check user shell in /etc/passwd and change it with chsh -s /path/to/new/shell - list of allowed shells is available in /etc/shells - but make sure to pick Bash/ZSH, also note that links like sh->bash will not work as bash changes behavior based on the name that was invoked.

I have tried to run:
uninstall_oh_my_zsh
but i get a message stating that: -bash: uninstall_oh_my_zsh: command not found
Other commands i have tried are:
chmod +x ~/.oh-my-zsh/tools/uninstall.sh
I get a response stating that: No such file or directory
sh ~/.oh-my-zsh/tools/uninstall.sh
Ran:
chsh -s /bin/bash
To change default terminal from /bin/zsh to /bin/bash
I also tried:
rm -rf ~/.oh-my-zsh
rm ~/.zshrc
cp ~/.zshrc.pre-oh-my-zsh ~/.zshrc
source ~/.zshrc
None of them have worked thus far, when i open my terminal. I get a message stating that:
The default interactive shell is now zsh.
To update your account to use zsh, please run chsh -s /bin/zsh
You don't have Oh My Zsh (a set of configuration files for zsh and a way to manage them) installed in the first place.
The warning is coming from /bin/bash itself; it's hard-coded into the executable supplied by macOS.
$ strings /bin/bash | grep "default interactive shell"
The default interactive shell is now zsh.
Though they don't say so, I suspect the warning is there because they plan to remove bash from future versions of macOS entirely. They stopped providing newer versions of bash years ago.
Your default shell is already /bin/bash; the warning is recommending that you switch to /bin/zsh.
You can continue to use bash, though I recommend installing a newer version (3.2 is old) using something like Homebrew, then changing your login shell to the new version.
However, unless you are really committed to using bash, I suggest given zsh a try.
I am trying to install Anthos Service Mesh (ASM) for a Kubeflow installation and need /bin/bash to be v5+. MacOS comes with Bash v3.2.57 which doesn't work. Simply installing Bash v5+ in "/usr/local/bin" doesn't work either as several shell scripts for the install points to "/bin/bash" and thus I still get the old version.
I had hoped I could just temporarily move the new bash v5+ to "/bin/bash" and then revert after completing the ASM install - something like this:
>>>$sudo mv /bin/bash /bin/bash_old
>>>$sudo cp /usr/local/bin/bash /bin
>>>$make install_asm
>>>$sudo mv /bin/bash_old /bin/bash
>>>mv: rename /bin/bash to /bin/bash_old: Operation not permitted
So that doesn't seem to be possible
What would be the best way to get around this? It doesn't seem to work just adding an alias to .zshrc in the hope that whenever I execute a shellscript with "#!/bin/bash" it would actually call "/usr/local/bin/bash":
~/.zshrc:
alias /bin/bash="/usr/local/bin/bash"
>>>$/bin/bash --version
>>>GNU bash, version 5.1.8(1)-release (x86_64-apple-darwin19.6.0)
test_bash.sh:
#!/bin/bash
/bin/bash --version
>>>$sh ./test_bash.sh
>>>GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin19)
Perhaps there is a way for me be permitted to move the binaries as in the example above?
By the way already the "/usr/local/bin/bash" is a link - not sure if that has any influence on what I am trying to do.
>>>$ll /usr/local/bin/bash
>>>/usr/local/bin/bash -> ../Cellar/bash/5.1.8/bin/bash
Any hints are warmly welcomed!
I used a combination of adding my new shell location to the list of approved shells in /etc/shells, then changing my user's default shell with:
chsh -s /path/to/new/bash/version
as well as making sure my new bash location was exported to the front of my path not the end, so commands looking for just any bash find that first:
export PATH=/opt/homebrew/bin/bash:$PATH
No issues with this for far but this is a new machine and I'm just getting it set-up. If you have a SHELL environment variable set in any of your bash start-up scripts make sure to change it to your new bash binary also.
When running bash scripts inside zsh-Terminal I want it to use the homebrew bash version 4 instead of the default 3 of OS X.
How can I do that?
I installed bash 4 on my MacBook.
brew install bash
Instead of using it as the default shell using the following command, I want to keep my zsh.
chsh -s $(brew --prefix)/bin/bash # BAD! as I lose zsh
Still I want to run:
./my-cool-bash.sh
Use the following shebang in your scripts:
#!/bin/env bash
This makes them use the first bash in the PATH; which is the one you want.
This solution works with any Bash on any UNIX-like system.
use your new bash path:
ex, if new bash is in /usr/local/bin/
/usr/local/bin/bash my-cool-bash.sh
or write first line of script:
#!/usr/local/bin/bash
you could put an alias in your .zshrc file, something to the effect of
alias mcb='./usr/local/bin/bash/my-cool-bash.sh so that you can call it from your normal zsh whenever you want.
Hi I've recently installed zsh using cygwin on my Windows machince but when I type zsh to start this I get the following:
GG#GG-PC ~
$ zsh
\[\e]0;\w\a\]\n\[\e[32m\]\u#\h \[\e[33m\]\w\[\e[0m\]\n\$
On my mac I am using iTerm2 and this is so much easier to setup on here. Also I am having trouble in setting up the aliases and this is becauses its not setup properly in terms of config file where I can set this up in a separate file.
Any ideas how I can resolve?
It looks like zsh is inheriting the value of PS1 from the previous shell. The PS1 environment variable sets the shell prompt, and zsh used a different format for prompt substitutions than other shells. Try entering the following command after you start zsh:
PS1=$'%{\e]0;%d\a%}\n%F{green}%n#%m %F{yellow}%d%f\n%# '
If that works, add that line to your ~/.zshrc file.
That's also probably a good place to put your aliases.
There might be an issue because you launch zsh from bash actually and not cygwin.
One thing you can do is to launch zsh as the starting shell of mintty (the window that wraps your shell)
Create a shortcut with this inside:
c:\<cygwin-folder>\bin\mintty.exe -i /Cygwin-Terminal.ico /usr/bin/zsh --login -
Yo need to update .zshrc with your required theme and then
source .zshrc
This has been frustrating me for two days and it seems like it should be a very simple thing. I was just created an account on a Solaris machine. Sun OS 5.10 I believe.
The default is Bourne shell which I don't want. I did a cat /etc/shells which results in:
/bin/sh
/sbin/sh
/bin/ksh
/usr/bin/ksh
Looks like Korn shell is all I can use.
I created a .profile file and wrote:
export SHELL=/usr/bin/ksh
Then I did a env and it looks like /bin/sh is still listed as my shell. I logged off, logged back on and now I get:
-sh: SHELL=/usr/bin/ksh: is not an identifier
I've tried adding #!/usr/bin/ksh at the beginning of the .profile. That didn't work. I've tried adding a semicolon at the end of the export. That didn't work. I've tried: SHELL=/bin/ksh and that didn't work either.
My end goal is to get this environment to a point where I can operate productively. I'm used to BASH where I have tab-completions, up-arrow for history, etc and this Bourne shell doesn't have any of that and it frustrates me to no end.
I know this must be simple but all my Googling comes to no avail. Can someone help me?
/etc/shells is not a standard Solaris file, you probably shouldn't rely on its contents.
On the other hand, bash is part of the default Solaris 10 installation. It should already be present as /bin/bash (/usr/bin/bash actually but /bin is a symlink to /usr/bin anyway).
If bash is not there, you might want to ask to the administrator to install the SUNWbash package from the Solaris_10/Product directory in the installation media.
Then, to update your shell, the regular way is to have the shell defined for your account updated. If it is local, that's the last field in your /etc/passwd entry.
Alternatively, you might use that hack at the end of your .profile:
[ ! "$BASH_VERSION" -a -x /bin/bash ] && SHELL=/bin/bash exec /bin/bash
In descending order of preference
ask the sysadmin to install bash and update /etc/shells and update your login shell
see if the chsh program is installed that will allow you to change your own login shell
ask the sysadmin to change your login shell to /usr/bin/ksh
modify your ~/.profile:
if type [[ >/dev/null; then
: # this is ksh
else
# not ksh
export SHELL; SHELL=/usr/bin/ksh
exec $SHELL
