Команды для работы с файлами и каталогами

pwd - print working directory

The pwd command displays the directory where the user is currently located. (pwd stands for print working directory). For example, typing

pwd

while in the Desktop will show /home/[username]/Desktop.

Note

Konsole also displays this information in both the tab and title bar of its window.

cd - смена директории

The cd command changes directories. (cd stands for change directory). When a terminal window is opened, it will be in the user's home directory. Moving around the file system requires the use of the cd.

  • To navigate into the root directory, type:

    cd /

  • To navigate to the current user's home directory, type:

    cd

    or

    cd ~

    Note

    The ~ character represents the current user's home directory. As shown above, cd ~ is equivalent to cd /home/username/. However, when running a command as root (using sudo, for example), ~ points to /root. When running a cd command with sudo, the full path to the home directory must be given.

  • To navigate up one directory level, type:

    cd ..

  • To navigate up two directory levels, type:

    cd ../../

  • To navigate to the previous directory (go back), type:

    cd -

  • To navigate through multiple levels of directories at once, specify the full directory path. For example, type:

    cd /var/log

    to go directly to the /log subdirectory of /var/. For another example, typing:

    cd ~/Desktop

    moves to the Desktop subdirectory inside the current user's home directory.

ls - list files

The ls command outputs a list of the files in the current directory. (ls is short for list). For example, typing

ls ~

will display the files that are in the current user's home directory.

Used with the -l option, ls outputs other information along with the filename, such as the permissions on the file, the file's owner, and more.

Used with the -al options, ls outputs the information associated with the -l option in addition to showing hidden files (a option).

touch - create empty file

The touch command is used either to change a file's access and modification timestamps or to create a new empty file. For example,

touch foo

will create a new empty file named foo. If foo is already a file, then using touch will update the timestamps on the file which will show the last time a file was touched.

mkdir - создание директории

The mkdir command is used to create a new directory. (mkdir stands for make directory). To create a new directory named foobar, type:

mkdir foobar

cp - копирование файлов или директорий

The cp command makes a copy of a file or directory. (cp is short for copy). To make an exact copy of foo and name it bar, type:

cp foo bar

To make an exact copy of the foo_dir directory and name it bar_dir, type:

cp -r foo_dir bar_dir

mv - перемещение файлов или директорий

The mv command moves a file or directory to a different location or will rename a file or directory. (mv is short for move). To rename the file foo to bar, type:

mv foo bar

To move the file foo into the current user's Desktop directory, type:

mv foo ~/Desktop

This will not rename foo to Desktop because foo is a file and Desktop is a directory.

rm - удаление файлов или директорий

The rm command is used to delete files and directories. (rm is short for remove). To delete the file foo for the current directory, type:

rm foo

By default, rm will not remove directories. To remove a directory, you must use the -r option (also can be entered as either -R or --recursive). For example,

rm -r foobar

or

rm -R foobar

or

rm --recursive foobar

will remove the directory foobar, and all of its contents!
