Creating multiple files at same time using touch command

[root@dev db_bak]# ls
file1  file2  file3  file4  file5

Creating a Directory:

[root@dev db_bak]# mkdir dir1
[root@dev db_bak]# ls
dir1

Making multiple directories inside a directory

 [root@dev ~]# mkdir -p technology/{linux/{shell_script,linux},java/{basic,adv_java},mysql/{DBA,Dev}}

[root@dev ~]# tree technology/
technology/
|-- java
|   |-- adv_java
|   `-- basic
|-- linux
|   |-- linux
|   `-- shell_script
`-- mysql
    |-- DBA
    `-- Dev

9 directories, 0 files
 

Copying files into directory

[root@dev ~]# ls
filename    

[root@dev ~]# cp filename technology/
[root@dev ~]# ls
filename  

[root@dev ~]# cd technology/
[root@dev technology]# ls
filename  java  linux  mysql

Copying directories from one location to other

[root@dev technology]# cp -rvfp java  linux/
‘java’ -> ‘linux/java’
‘java/basic’ -> ‘linux/java/basic’
‘java/adv_java’ -> ‘linux/java/adv_java’
[root@dev technology]# cd linux/
[root@dev linux]# ls
java  linux  shell_script

Moving files from one location to other (cut and Paste)
[root@dev technology]# ls
filename  java  linux  mysql
[root@dev technology]# mv filename  java/

[root@dev technology]# cd java/
[root@dev java]# ls
adv_java  basic  filename

Moving a Directory from one location to other

[root@dev technology]# ls
java  linux  mysql
[root@dev technology]# mv java/ linux/
[root@dev technology]# ls
linux  mysql
[root@dev technology]# cd linux/
[root@dev linux]# ls
java  linux  shell_script

Renaming a File

[root@dev linux]# ls
java  linux  shell_script
[root@dev linux]# mv linux/ linux_adv
[root@dev linux]# ls
java  linux_adv  shell_script

[root@dev linux]# rm file

rm: remove regular empty file ‘file’? y
