1. Mastering the grep Command

The grep command is a powerful tool for searching text patterns in files. Some useful options include:

• Searching for a pattern in a file: grep "pattern" file
• Searching recursively in directories: grep -r "pattern" directory
• Ignoring case sensitivity: grep -i "pattern" file
• Displaying line numbers: grep -n "pattern" file

2. Navigating the File System with cd and ls

• Changing directories: cd directory_name
• Going back to the previous directory: cd ..
• Listing files and directories: ls
• Displaying detailed file information: ls -l
• Sorting files by modification time: ls -lt

3. Stream Editing with sed

sed (stream editor) is a command-line utility for performing text transformations. Here are a few examples:

• Replacing text in a file: sed 's/old_text/new_text/g' file
• Deleting lines that match a pattern: sed '/pattern/d' file
• Printing specific lines: sed -n '2,5p' file

4. Efficient File Transfers with rsync

The rsync command allows efficient synchronization and file transfers between directories or across networks. Some useful options include:

• Synchronizing directories: rsync -av source_dir/ destination_dir
• Transferring files over SSH: rsync -avz -e "ssh" source_file user@host:destination
• Excluding specific files or directories: rsync -av --exclude 'file.txt' source_dir/ destination_dir

5. Monitoring System Resources with top

The top command provides real-time monitoring of system resources. It displays information about CPU usage, memory, processes, and more. Some useful options include:

• Sorting processes by CPU usage: Press Shift + P
• Sorting processes by memory usage: Press Shift + M
• Renicing a process: Press r and enter the process ID
