What Linux commands do you know? Share a case of working with the console.

In Linux, there are many useful commands for working with the console. Here are some basics:

• ls — displays a list of files and folders in a directory.
• cd — changes the current directory.
• pwd — shows the current path.
• cat — outputs the contents of a file.
• grep — searches through text.
• ps — displays running processes.
• kill — terminates a process.
• chmod — changes file permissions.
• tar, zip — archiving.
• ssh — connecting to remote servers.

Example case:

Suppose you need to find all error lines in logs, compress them, and send to a remote server.

cd /var/log/myapp
grep "ERROR" *.log > errors.log
zip errors.zip errors.log
scp errors.zip user@remote-server:/home/user/

Here, we navigate to the log folder, find all errors, save them to a file, archive, and copy to a remote server via SSH.

This set of commands allows efficient work with files, processes, and remote systems directly from the console.
