Current Directories

The current directory is the directory you are currently working on. Current means "current" in English. A directory in Linux corresponds to a folder in Windows.

Change current directory

Use the cd command to change the current directory.

cd /home/kimoto/labo

The directory "/home/kimoto/labo" will be the current directory.

Specify a relative path from the current directory

As an effect of setting the current directory, the file name can be specified from the current directory with relative path.

Let's specify the file "foo" with a relative path with the ls command.

ls foo

This actually has the same meaning as specified by absolute path as shown below.

ls /home/kimoto/labo/foo

File name of the current directory

The current directory itself is represented by a special file name ".".

# File name of the current directory
..

If you give "." To ls and execute it as shown below, a list of files in the current directory will be displayed.

ls .

Check the existence of the current directory

The current directory actually exists as the contents of the current directory as hidden files.

Let's check using the "-a" option of the ls command. This is a sample output result.
