I just have installed Catalina on my imac, and I saw a terminal bash looks weird.
It should be ~$ but my terminal shows ~%
Can anyone change this uncommon line(~%) to a normal line(~$)?
Thank you in advance
You can set your PS1 variable in your .bashrc, .bash_profile, or .profile to whatever you want. For example:
export PS1=“\h \W $ “
Will give your hostname, current working directory, followed by the $ you wanted. This can be customized however you like, see this link for a good description.
Also, as chepner mentioned in the comments, you need to set your default shell back to bash. I believe the easiest thing to do is go into your terminal settings, and change your shell:
Terminal > Preferences... > General > Shells open with: Command (complete path): /bin/bash
For a long time, the bash was a default shell in macOS. However, Apple replaced Bourne Again SHell with Z shell for licensing reasons
Set default shell to bash on Macos Catalina. The procedure is as follows:
Open the terminal application.
List available shells by typing cat /etc/shells.
To update your account to use bash run chsh -s /bin/bash.
Close terminal app.
Open the terminal app again and verify that bash is your default shell.

I am seeing a strange problem with the storing of an env in mac os.
I set custom env in ~/.bash_profile
export MYENV=user
Then ran the . ~/.bash_profile and then I printed the env using
printenv then I can see the MYENV=user in the list.
If I close the terminal and reopen and execute printenv then I could not see MYENV in the list still I can see the export MYENV=user in ~/.bash_profile. It seems strange to me.
I am using Mac os High Sierra 10.13.6.
Could some body please tell me what mistake I am doing?
Note that ~/.bash_profile is only run for login shells. From the man page:
When bash is invoked as an interactive login shell, or as a non-interactive shell
with the --login option, it first reads and executes commands from the file
/etc/profile, if that file exists. After reading that file, it looks for
~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and exe-
cutes commands from the first one that exists and is readable. The --noprofile
option may be used when the shell is started to inhibit this behavior.
So if you terminal isn't launching the shell with -l, --login or with $0 having a leading hyphen it won't be a login shell and thus won't read ~/.bash_profile. You may need to reconfigure how your terminal launches the shell if you want the shell to read that config script.
On the other hand ~/.bashrc is always read by an interactive shell. So if you put the export in that script it should do what you expect. It certainly does for me. You replied to Amila that it didn't work for you. So I'd suggest a simple experiment. Open two terminal windows. In one edit ~/.bashrc and add these two lines:
echo running .bashrc
export WTF=abc
In the other window just run bash. It should echo that message and echo $WTF should print abc. Now open a new terminal window. If you don't see that message and the env var isn't present then something is inhibiting reading that config script. Possibly the shell is being run with the --norc flag.
~/.bash_profile is executed before the initial command prompt is returned to the user, which means after a new login. Try adding the environment variable to ~/.bashrc instead.
I just upgrade pycharm into 2016.3.1. Before upgrade, I do not have problem to see the current directory path under the prompt on terminal window. After upgrade into pycharm 2016
3.1. All directory path on prompt on terminal window seems like messed up with 133;C;133;D;01337;RemoteHost=hawkins#pc_name.home1337;CurrentDir=/Users/hawkins/path133;MAC:path hawkins$ 133;B for some reason. Anyone have expereience on how to resolve this?
MAC:path$
133;C;133;D;01337;RemoteHost=hawkins#pc_name.home1337;CurrentDir=/Users/hawkins/path133;MAC:path hawkins$ 133;B
133;C;133;D;01337;RemoteHost=hawkins#pc_name.home1337;CurrentDir=/Users/hawkins/path133;MAC:path hawkins$ 133;B
133;C;133;D;01337;RemoteHost=hawkins#pc_name.home1337;CurrentDir=/Users/hawkins/path133;MAC:path hawkins$ 133;B
I had a similar problem. It turned out my problem was due to have iTerm shell integration installed.
As you have tagged the question [osx], I assume that you might also have done this.
There is a nice explanation to what these strange symbols mean in this answer: https://unix.stackexchange.com/a/294886/47407
I figured I could avoid having to uninstall Shell Integration by clearing my PROMT_COMMAND, and setting PS1 again. I made a shell script called pycharm_terminal.sh with the following
export PROMT_COMMAND=
export PS1="\[\e[31m\]\u\[\e[0m\] at \[\e[33m\]\h\[\e[0m\] in \[\e[32m\]\w\[\e[0m\] at [\A] \[\033[31m\]`git branch 2> /dev/null | grep -e ^* | sed -E s/^\\\\\*\ \(.+\)$/\(\\\\\1\)\ /`\[\033[35m\]\n$ \[\033[00m\]"
bash -i
The PS1 variable can be set to whatever you had before. This is just how I like mine.
Now, in PyCharm Settings: Go to Tools > Terminal and in "Shell path" set it to /bin/bash <path_to_pycharm_terminal.sh>.
Now try opening a new terminal in PyCharm. It shouldn't have those control character errors.
Solution that worked for me:
Go to Settings > Plugins
Find plugin "Python Terminal" and disable it
Restart PyCharm
The only negative effect I've noticed - auto activation of virtualenv on terminal start doesn't work.
for some reason, I figure it out by create a .pycharmrc under by user directories
and setting up /usr/local/bin/bash --rcfile ~/.pycharmrc under Tool->Terminal on shell path. It seems like it fixed but i have no idea why
MAC: path$ cat ~/.pycharmrc
exec bash
This is what worked for me:
Created new file pycharm_terminal.sh with one command bash -l
Then I set PyCharm Settings: to Tools > Terminal and in "Shell path" set it to /bin/bash/path_to_pycharm_terminal.sh.
Restart PyCharm and all work as expected
bash -l, by man, is a: -l Make bash act as if it had been invoked as a login shell (see INVOCATION below).
which is probably mean, that when PyCharm starts the Terminal and executing the pycharm_terminal.sh with bash -l, everything in .bash_profile is include by default
Found this question while trying to resolve similar issue for 'Geany' on mac osx. I had an install of iterm2 on my machine and was getting garbage in front of the terminal prompt.
similar solution as KPLauritzen offered also works for 'Geany' terminal as such.
Hope this helps someone:
Create shell script in home directory using desired PS1 & CLICOLOR settings:
~/geany_terminal.sh
export PROMT_COMMAND=
export PS1='[\e[1;32m][\u#\h \W] \D{%F %T}\n\$[\e[0m]'
export CLICOLOR=1
export LSCOLORS=gxBxhxDxfxhxhxhxhxcxcx
bash -i
Then I went to 'Edit -> Preferences --> Terminal' and set my 'Shell' to:
/bin/bash /Users/myusername/geany_terminal.sh
Upon reloading Geany, the Terminal now displays with PS1 and CLICOLOR settings exactly as I have set in my .bash_profile without garbage in front.
You can just activate your .bash_profile
/bin/bash --rcfile ~/.bash_profile
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
I have installed Hadoop and every time I want to run it, first I have to do this:
source ~/.bash_profile
or it won't recognize the command hadoop
Why is that?
I am on OSX 10.8
Now that we've narrowed down the problem:
Run ps -p $$ at the command line to check if you are, in fact, using a bash shell.
Realize that you are in zsh, which means you should be editing your profile in .zshrc.
Copy the offending lines from .bash_profile to .zshrc, OR
Modify your .zshrc to directly source your .bash_profile.
UPDATE: Do what #TC1 mentions in the comments and keep the shell-specific code in each shell's own profile, and from those profiles, only source shell-agnostic code.
On Mac Catalina, I just had to open "preferences" on terminal and change the "shells open with" from "default" to "Command(complete path)", which the default path was "/bin/zsh". touch ~/.zshrc, if that file doesn't exist already, and copy/paste your stuff from ".bash_profile" into the ".zshrc" file.
To elaborate, with terminal running, I opened "settings" from the Terminal menu on the Mac navbar. On the "General" tab, look for "Shells open with" select "Command (complete path)", and type in /bin/zsh.
bash_profile.sh is applicable for bash shell.
if your default shell is not bash and if your default shell is someother shell for example zsh then you have to manually load the .bash_profile using source ~/.bash_profile.
You can always change the default shell to bash shell so that the .bash_profile file will be automatically loaded.
Inorder to automatically load .bash_profile, you can update your default shell to bash using the command chsh -s /bin/bash
cat /etc/shells will list the default shells available in the
machine
echo $SHELL will display the currently active shell in your machine
To change active shell to a different shell, use chsh -s /bin/bash.
Then echo $SHELL to verify if the shell has changed.
Terminal -> Preference -> profile -> Shell -> Run command : source ~/.bash_profile
Tick on run inside shell.
After doing all those , just logout and check weather everything works fine or not
I tried the approved answer. Changing the .zshrc file works for one of my machines. But for the other one, when I run ps -p $$, it is -sh under the command. And I changed both bash and zsh files, neither of them works for me this time.
So I found this
https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html
it mentioned
"When Bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. "
so I went to that file /etc/profile and add "source ~/.bashrc" in that file. Then it works since every time a terminal is opened, it runs the command in that /etc/profile file.
Not sure if this is the best solution but it works.
sudo nano /etc/bashrc and change that, restarted the terminal and it finally remembered with command. Tried ~/.bash_profile and ~/.bashrc without success, just wasn't sourcing it.
Go to “Preferences/Profiles then look in the right window and find “shell”.
Once in that if your “Startup Run Command” hasn’t been turned on. Click the box to turn it on and in the command section type:
(If you made a .zsh file)
source .zsh ; clear
(If you made a .bash_profile)
source .bash_profile ; clear
Doing this ; clear
Will clear your terminal to a new page so that you don’t see your terminal display:
“Last login: etc
User#user-Mac ~ % source .zsh
If you typed the commands as I said you should just get this:
User#user-Mac ~ %
That way you will be greeted with a clear page with no extra jumbo. Also to make sure that your .zsh or .bash_profile aliases work type the following command to see a list of your custom aliases:
Alias
One alias I like to do is
alias LL=“ls -la”
This will display a tree or the directory you are in as well as hidden files.
I'm looking for a way to make the cygwin terminal more compact, or an alternate terminal that is more compact. Currently, every command I enter has a header line above it with username and pwd, and there is a blank line trailing every command. For instance:
username ~
$ cd tmp
username ~/tmp
$
3 lines for every 1 line of command. I frequently work on a small screen, which makes all this wasted space quite irritating. Is there a setting somewhere I can alter to prevent all this wasted space? Or, perhaps another terminal?
Thanks in advance.
That's the default shell prompt set by Cygwin.
To use a smaller prompt in your current terminal:
PS1='$ '
To make the change permanent, put that command in your ~/.bashrc file.
You can set the prompt to just about anything you like, as explained by the bash manual (there are several variables that control different prompts; $PS1 is the main one).
It's important to remember than in Cygwin (as in Linux and Unix), the terminal program is a separate program from the shell that runs in it. The prompt is controlled by the shell; bash is the default. The graphical display is controlled by the terminal emulator, which could be rxvt, mintty, xterm, or even the Windows terminal that normally runs a DOS-like shell.
What you're seeing there is the prompt, as stored in the environment variable PS1
echo $PS1
will show you how it's created. By the way, that prompt is managed by the bash shell, not by the terminal.
export PS1=$
will give you just a $ prompt
export PS1="$ "
will leave some room behind the prompt. There are many more possibilities, here is a nice tutorial.
bash reads its settings from a file called ~/.bashrc aka a file called .bashrc in your home directory. Note that due to the initial dot in the name ls won't show the file by default, ls -a or ls -la will.
I would Recommend we go with modern terminals using Cygwin-X as shown in the below interactive menu
I love Xfce Terminal which allows creating tabs and new windows with font options and color options
