Ποια είναι η εμπειρία σας με την κονσόλα στο Linux; Μπορείτε να δώσετε παραδείγματα εντολών και ρυθμίσεων δικαιωμάτων;

More than N (indicate your actual experience) years in various distributions (Ubuntu, CentOS, Debian, Alpine). I freely use standard utilities and scripts for automation.

Examples of commands:

• Viewing process information:

  ps aux | grep <process_name>
  

• Checking disk space usage:

  df -h
  

• Downloading a file:

  wget <file_URL>
  

• Extracting an archive:

  tar -xzf <archive_name.tar.gz>
  

• Editing a file with vim:

  vim <file_name>
  

Configuring access permissions:

• Using chmod to change permissions (owner, group, others; read, write, execute):

  chmod 755 <file_or_directory_name> # Owner: read, write, execute; Group: read, execute; Others: read, execute
  chmod +x <script_name> # Add execute permission for all
  

• Using chown to change the owner of a file or directory:

  chown <new_owner>:<new_group> <file_or_directory_name>
  

• Setting Access Control Lists (ACLs) with setfacl and getfacl for more granular permission management:

  setfacl -m u:<username>:rwx <file_name> # Grant user read, write, execute permissions
  getfacl <file_name> # View file ACL
  

I regularly use pipelines (|), input/output redirection (>, >>, <) and have studied and applied more advanced utilities like awk, sed, and scripting in bash for deployment, monitoring, and administration automation.
