Would love to see something about pushd and popd in addition to cd. They can be very handy tools when you changing directories a lot and need to make a quick escape to where you've previously been! :)
Can't wait to see more!
Thanks for your response, i'll keep updating this page.
I think an important concept is also where a user's shell is defined.
A user's shell is typically setup when the user is added to the system. Often /bin/bash is set as a default, but macOS now sets /bin/zsh as the default shell for users.
A user could find their default shell by viewing the
/etc/passwdfile. For example,In the above example root's default shell is set to the Bash shell. While the games user actually has been set to a nologin shell, preventing anyone from logging into the user. This has certain uses for non-interactive user sessions. We have other shell options that we can use as well. There are lots of varieties and it depends on your OS, or what the administrator has set at account creation.
There are different commands to modify a user's shell. But one way you can do this is with the usermod command:
usermod -s /bin/bash USERIf you want to find a list of available shells on your system, try this command:
cat /etc/shellsThere's no such thing as a Linux shell. There are only various shells, e.g., bash, tcsh, zsh, etc. You can use exactly the same shells on FreeBSD, macOS, and others as you can on Linux.
@pauljlucas Yeah, you are correct mate, thanks for the help, i've updated the title accordingly.
You might want to reconsider the banner image and
#linuxtag as well.You still mention "Linux shell....". You ought to replace that with "A shell...."
sure, i'm working on it
I’m glad to see folks still talking about the terminal. That said, none of this is bash-specific. These will all work in a variety of shells, and I hope folks find whatever shell they prefer and have a great time in the shell.
You mention commands, but never once mention the
PATHenvironment variable or explain that commands likemkdir"live" in certain directories and the way commands work is that the shell searchesPATHfor a matching command.In my opinion "how bash works" is also an important topic for a beginners, Don't you think so?
Beginners with no experience with bash, see the black screen and don't know what to write on it.
From my Teaching experience, they are more interested in, How to use it.
not "How it works".
I hope you understood my point, sir.
Thanks for your Feedback though
