BSC OS LAB PROGRAM TO UNDERSTAND BASIC LINUX COMMANDS

-

 pwd command

The pwd command allows you to print the current working directory on your terminal. It’s a very basic command and solves its purpose very well.

adc@2lab-PC-60:~$ pwd

Output: /home/adc


mkdir command

The mkdir command allows you to create directories from within the terminal.

adc@2lab-PC-60:~$ mkdir avrk

adc@2lab-PC-60:~$ cd avrk

adc@2lab-PC-60:~/avrk$ 



rmdir command

Removes an empty directory.

adc@2lab-PC-60:~$ rmdir avrk

adc@2lab-PC-60:~$


grep command

The grep command stands for “global regular expression print,” which reflects its ability to search for regular expressions across multiple lines and files.

dc@2lab-PC-60:~$ grep "pwd" linux

Output:

pwd command

The pwd command allows you to print the current working directory on your terminal. It’s a very basic command and solves its purpose very well.



chmod and chown commands

The chmod and chown commands are used to modify file permissions and ownership in Linux.The chmod command is used to change the permissions of a file or directory, and the chown command is used to change the ownership of a file or directory. 

The default syntax for both the commands is chmod <parameter> filename and chown <user:group> filename

adc@2lab-PC-60:~$ chmod u=rwx,g=rx,o=r linux

adc@2lab-PC-60:~$



ls command

The ls command is used to list files and directories in the current working directory. This is going to be one of the most frequently used Linux commands you must know of.

adc@2lab-PC-60:~$ ls



rm command

The rm command is used to delete files and folders and is one of the important Linux commands you must know.

dc@2lab-PC-60:~$ rm linux


cp and mv commands

The cp and mv commands are equivalent to the copy-paste and cut-paste commands in Windows. But since Linux doesn’t really have a command for renaming files, we also use the mv command to rename files and folders.

adc@2lab-PC-60:~$ cp linux linux2
