When I make some changes to the shell/bash behavior, such as setting up an alias, is there a quick command to reinitialize the terminal window instead of closing and opening a new window?
If you mean reloading your .bashrc configuration then:
For less typing, you can replace
source with a dot:
Some Addition i found in the manpage from the reset/tset command
tset reset terminal intialization
Tset initializes terminals. Tset first determines the type of terminal that you are using. This determination is done as follows, using the first terminal type found.
an advantage seems to be, that it's independent from the used shell. also works with fish here.
So to reinitialize any terminal just do-
An additional option to the
exec bash is that if you changed your
.bash_profile), you can do
$ exec bash --login
That will read your profile again as well. It wouldn't hurt to add the
-i option as well to explicitly tell bash that this is an interactive shell, but it can normally figure that out for itself.
You have to replace the running application/shell with a new instance. E.g. if you are using
bash as your preferred shell type the following line in your command line ($ is the placeholder for the beginning of your command line):
> $ exec bash
The running application/shell is replaced by new instance of
bash like starting from scratch. All your previous modification are gone.
Remark: Do not forget that your terminal application may be reprogrammed. You have to reset your terminal application manually.
your shell is an executable you can call. So if you're using bash you can call
bash and if you're using something else like zsh you can just enter
exec sudo --login --user $USER.
If you also want the previously entered commands to disapper (full reset of the terminal), combine it with
reset; exec sudo --login --user $USER
There are many answers around the web but most don't actually work. Easy way to test is to set
export SOMEVAR=42 then execute the supposedly resetting command and do
echo $SOMEVAR. If it's 42, the environment was not reset.
There is also
exec -c bash -l or
exec env -i bash -l, but these are broken, somehow the $HOME variable is not set after this.
