Linux Shell: File directory Operations and instances

This article describes the underlying file operations: Create, move, edit, delete files and folders

Command and Case:

mkdir Creating a Directory

--Create two directories

[Email protected]:~$ mkdir test2 test3

--Create a new directory under Test1 Mydir

[Email protected]:~$ mkdir Test1/mydir

--Try to create a new directory under test100 Mydir, but not successful because test100 this directory does not exist

[Email protected]:~$ mkdir test100/mydir mkdir:cannot Create directory ' Test100/mydir ': No such file or directory

--Force the creation of two files for father and son, although test100 this parent directory does not exist

[Email protected]:~$ mkdir-p Test100/mydir

Touch Create File

--Create a hello file in the current directory

[Email protected]:~$ Touch Hello Echo

--write "Hello" to this directory

[Email protected]:~/test1$ cat Hellobackup[email protected]:~/test1$ echo "Hello" > hellobackup [email protected]:~/ test1$ Cat Hellobackuphello

MV Move or rename files

--Move the file hello to the Test1 folder

[Email protected]:~$ mv Hello Test1

--Rename file Hello to Hellobackup

[Email protected]:~/test1$ mv Hello Hellobackup

CP Copy File

[Email protected]:~$ cp pse2 test2--Copy file Pse2 to Test2 folder

Rm/rmdir deleting files and folders

--Delete File Hello

[Email protected]:~$ rm Hello

--Delete Folder Test2
[Email protected]:~$ rmdir test2

Input Redirect to file:

The following will write the input of the interface to the file Hellobackup file

[Email protected]:~$ cat <<eof >hellobackup> Hello world!> real func> EOF

Often read the contents of the file [email protected]:~$ cat Hellobackuphello world!real func[email protected]:~$
