Change file directory linux

OR cd

Let us see all examples and usage for terminal in details.

How to use the Linux command line to change directory or folder

The directory in which the user is currently working is called the current working directory (CDW).

How to print the current working directory in Linux

To display the name of the current/working directory, type the following pwd command:
pwd

cd command in Linux termianl

The syntax is:
cd
cd ..
cd /path/to/dir
When cd command used without stipulating any directory name, cd command returns to the home directory. Let us change the directory to /usr/sbin/, run:
cd /usr/sbin/
Verify it:
pwd
Want to list the files in the /usb/sbin/ directory? Try the ls command:
ls
ls -l
Let us go back to user’s home directory, run:
cd
Again verify it:
pwd

Absolute vs Relative pathname

The cd command changes the current directory when a directory name provided by the user. The name can be written as an absolute pathname (e.g. cd /etc/httpd/ ) or as local pathname relative to the root directory (e.g. cd conf.d/ ). For example:
cd /etc/httpd/
pwd
ls
cd conf.d/
pwd
ls

The absolute vs. relative pathname for cd command in Linux

Understanding . and .. directories

On Linux the current directory is represented by a single dot ( . ) and two consecutive dots represent its parent directory ( .. ). Thus, to change to the parent of the current directory, run cd . .. For example:
ls
pwd
cd ..
pwd
ls

How can I return directly to my home directory when using the Linux terminal?

How do I change directories in the Linux terminal and return to the previous directory?

Simply pass the — option to the cd:
cd —
Verify it:
pwd

A note about symbolic links and cd command

The -P option instructs cd to use the physical directory structure instead of following symbolic links:
cd -P LinkDir
pwd
The -L option forces cd to follow symbolic links:
cd -L LinkDir
pwd

Linux cd command cheat sheet

Also returns you to your login directory cd — Returns you to your previous working directory cd / Takes you to the entire system’s root directory. cd /root Takes you to the home directory of the root user. You must be the root user to access this directory. cd /home Takes you to the home directory, where user login directories are usually stored cd .. Takes you to the directory one level up. cd

tom Takes you to tom’s home directory, if tom user has granted you permission cd /path/to/dir/ Take you to the /path/to/dir/ directory cd dir* Use a wildcard to change the directory name

Conclusion

The cd command is used to change the current directory in both Linux and other Unix-like systems. See Cd command wiki page.

How to Change File/Directory User and Group Ownership in Linux

Linux is a multi-user system that can be accessed simultaneously by multiple users.

File permissions are a way to restrict users to access other user’s files on Linux.

It is controlled by file ownership and file permissions.

Each file in Linux has 3 types of owners, it’s user, group, and others.

A user is the owner of the file, and group is the one to which the user belongs to.

Each file and directory has three permissions for all three owners, such as read, write, and execute.

This can be done using the chown command and the chgrp command.

By default these commands do not display any output, so use the “-v” option to get information about what’s being done.

Use the ls command to find out who owns a file and which group the file belongs to.

What’s chown Command

The chown command is used to change the user and/or group ownership of each given file. This allows the user to perform various actions and the details are described below.

The common syntax is as follows:

• USER – If you provide only a username, the group of files will not be changed, becoming the owner of a given user file.
• USER: – If you provide a username followed by a colon, the given user will become the owner of the files and the group of files will be converted into that user login group.
• USER:GROUP – If you provide a username followed by a colon and group name, the given user will become the owner of the files and the group of files.
• :GROUP – If you provide a group name after the colon, and owner is excluded, only the group of files will be transferred. It works the same way as chgrp.
• : – If you only provide a colon, no action is performed.

Alternatively, you can use “-c” switch instead of “-v” switch, it works like verbose but report only when a change is made.

1) How to Change the Owner of a File/Directory on Linux Using the chown Command

In this example, we are going to change the ownership of the “passwd-up.sh” file from “daygeek” to “root”.
Before

2) How to Change the Group Ownership of a File/Directory on Linux Using the chown Command

In this example, we are going to change the group ownership of the file “mysql_backup.sh” from “daygeek” to “root”.

3) How to Change the User and Group Ownership of a File/Directory on Linux Using the chown Command

Use the example below to change the file’s user and group ownership. In this example, the user and group ownership of the “test.txt” file will be changed from “daygeek” to “root”.

4) How to Change the User and Group Ownership Recursively on Linux Using the chown Command

In this example, the ownership of all the files and its sub-directories is changed from “daygeek” to “root”, which includes the parent directory rights.

5) How to Change User and Group Ownership of Multiple Files on Linux Using the chown Command

To change the user and group ownership of multiple files, use the example below.

6) How to Change the User and Group Ownership of Link Files on Linux Using the chown Command

Use the following examples for changing ownership of link files.

When you use the chown command as usual in link files, it only changes the ownership of the source file, not the link file itself. In this example, it changes the ownership of the “output.txt” file from “daygeek” to “root”.

Use the “-h” option with the chown command to change the ownership of the link file instead of the source file.

Note: “-L” and “-H” options can be used when recursively changing the symbolic link directory ownership.

7) How do i Change the User and Group Ownership of a File Using the “–from=” option Using the chown Command?

Alternatively, you can use the “–from=” option to change ownership of files.

8) How to Copy User and Group Ownership from One File to Another on Linux Using the chown Command

In some cases, if you want to copy ownership from one file to another, use the example below.
In this example, the owner permission is copied from the “2.txt” file to the “renu.txt” file.

9) Bonus Tips: How To Find And Change Ownership of Files Based On Specific Extension

In this example, the ownership of the “.sh” extension files will be changed to “daygeek”.

How do I change directories in the terminal, and know which directory I’m in?

How do I tell what is in which directory and how do I navigate the directory. I know I must be leaving out something simple.

3 Answers 3

In your session ls displays the content of the current directory (but not hidden files starting with a dot in the filename). You navigate into another directory by typing cd dirname . Here you have to substitude «dirname» by a directory’s name you want to change into. Normally you start out with your home directory as current working directory. In your case that is most likely /home/christy . If ls shows you a directory called «Template» you can change into «Template» (=make it your current working directory) by typing (mind the space) the command:

you will change your current working directory to «Templates» or print «No such file or directory», if a dir of that name does not exist in your current direcotry. Typing pwd will always give you the full patch to your current working directory including parents.

You can supply optional arguments to each command. For cd the string «Templates» was such an optional argument. If you type ls -a for instance, the ls command will print out hidden files as well. Or with ls Templates it will print the content of the Tempaltes directory instead of you current working dir’s content. Arguments must be separated by at least one space from the command name and from each other. The lack of a space between the two was the reason your command did not work.

Since the space character has a special meaning, you will need to quote or escape it, if it’s part of an argument. So if for instance you want to change your current working directory to «Source Files» you need to type one of these commands:

The upper line being «escaped» while the lower line is «quoted».

Edit:

Okay now, sorry I didn’t see your link there. Your post was a bit misleading, now I think I got you:

So you want to install tex-live from the source archive that is linked in the «Getting Started» guide you posted. To do that you must first remove any pre-existing installation of tex-live. You do that by opening a terminal doing this:

At this point you have to enter you password and will be rewarded with a few boring messages, that I will omit here. Then you’ll have to download the archive named install-tl-unx.tar.gz (you already did that and don’t have to download it again, but I show you how to do it none the less just in case):

Now that you have downloaded the archive you can unpack it

Now that you’ve unpacked the archive you can change into the directory that was unpacked.

The number «20120701» is a timestamp saying which version of tex-live you have. This number might be different for you but the command ls | grep install-t1- will tell you what to use instead. If all this worked, you can run the install script from here:

From here on just answer the questions you’re asked by the install script and you should be fine.
