Hi everyone today I learn about the basic of Linux command ,GUI,CLI After learn GUI and CLI I realize that in window all the functions which we are performed its very time taking on other Linux all the functions are working very fast only We have to Give command on the CLI (Command line Interface), there are some Command which i learn is...
- Check your present working directory.
How to check where I am on so checking command is pwd (present working directory)
- List all the files or directories including hidden files.
On next i learn about the ls Command from ls command we can check or list all the Files and directory
- Create a nested directory A/B/C/D/E
the next command id mkdir -p command this commands is help us to create multiple directory at a time.
Many more command are like
Cat command (helps us to view the details of the file or directory (cat file name)
mv command helps us to move file or directory to another file or directory (mv source file destination file )
cp command its helps us to copy file or folder (cp source file destination file)
Touch command its helps us to create file (touch file name)
vi command is help us to open editor tool on Linux (vi file name)
cd: Change directory. Use it to navigate between directories. For example, cd /home/user/Documents will take you to the "Documents" directory.
rm: Remove files or directories. Be careful with this one, as it permanently deletes files. For example, rm file.txt will delete the file named "file.txt".
rmdir: Remove empty directories. Similar to rm, but specifically for directories that are empty.
chmod: Change file permissions. Use it to change the permissions of a file or directory. For example, chmod 755 script.sh will give read, write, and execute permissions to the owner, and read and execute permissions to the group and others.
grep: Search for patterns in files. It's very handy for finding specific text within files. For example, grep "keyword" file.txt will search for the word "keyword" in the file "file.txt".
sudo: Execute a command as the superuser or another user. It's used to perform administrative tasks. For example, sudo apt-get update will update the package lists on Ubuntu-based systems.
find: Search for files and directories. It's useful for finding files based on various criteria such as name, size, or permissions. For example, find /home/user -name "*.txt" will find all files with a ".txt" extension in the "/home/user" directory.
These are just a few examples, but there are many more commands and options available in Linux. Keep exploring, and let me know if you have any specific questions or if there's anything else you'd like to learn!
