ls: Perhaps the most fundamental command, ls, lists the contents of a directory. By default, it displays the names of files and directories in the current directory.
cd: Short for “change directory,” cd allows you to navigate between different directories within the file system. Simply specify the directory you want to move to as an argument. DevSecOps Course in Hyderabad

cp: Need to make a copy of a file or directory? Cp allows you to do just that. Specify the source file/directory and the destination.
mv: Similar to cp, mv moves files and directories from one location to another. However, mv also serves as the command to rename files and directories.
cat: Short for “concatenate,” cat is primarily used to display the contents of a file. It can also be used to create, concatenate, and display files.
more/less: When dealing with large files, more and less come in handy for viewing file contents page by page. Less provides more advanced features like searching and navigation. DevSecOps Training Online
grep: Need to search for a specific pattern within a file? Grep allows you to search for text patterns using regular expressions.
chmod: Stands for “change mode.” Chmod is used to modify the permissions of files and directories, determining who can read, write, or execute them.
chown: Short for “change owner,” chown allows you to change the ownership of files and directories. DevSecOps Training Institute in Hyderabad
