Linux CentOS Zip is a file packaging and compression utility ... gzip and zip are both compression tools, but they operate differently and use different algorithms. gzip is primarily used for compressing single files while zip is used for creating and extracting ZIP archives, which can contain one or more files or directories. -------------------------------------------------------------------- zip/unzip: commands 👉 To create a zip archive: type : zip archive.zip filesname 👉 To create a ZIP archive containing all files and folders in the current directory, you would type : 👉 zip archive.zip * 👉 To extract a zip archive: type : unzip archive.zip 👉 To view the zip file: type : unzip -l archieve.zip if you want to contain only 2 or more files and folders in a zip archieve then type - 👉 zip archieve.zip filename1.txt foldername ... 😎 👍

Hey #LinkedIn Community! I've just created a new video demonstrating some Linux commands that are essential for any developer or system administrator. grep - Search for a string in files. Command: grep "search_term" filename Use Case: Quickly find specific text within files. head - Display the first lines of a file. Command: head -n 10 filename Use Case: View the beginning of a file for a quick overview. tail - Display the last lines of a file. Command: tail -n 10 filename Use Case: Check the end of a file, perfect for monitoring logs. diff - Compare two files line by line. Command: diff file1 file2 Use Case: Identify differences between two files easily. cmp - Compare two files byte by byte. Command: cmp file1 file2 Use Case: Perform a precise comparison between files. comm - Compare two sorted files line by line. Command: comm file1 file2 Use Case: Find common and unique lines between sorted files. #data #technology #Linux #ArtificialIntelligence

I learned a bit of Linux command line syntax tonight. CONTROL-H deletes a character. Say what? CONTROL-W deletes a word. Akay that's cool. !! means the last command. So you could rerun the last command but using sudo: $ apt update <complains about your permissions levels> $ sudo !! <Prompts for your password.> And !$ is the last word of the last run command. So if I run: $ cat memo.txt I could then run the "file" command on the same file by just running: $ file !$ My favourite command so far (which I had to install) is "sl". Not to be confused with "ls", which lists the items in a directory. "sl" stands for Steam Locomotive. And that's what you get, chugging across your screen.

#day08 of #LinuxTips 🤔 Do you know how to search and interact with files in #Linux? #find command searches for files in a diretory hierarchy. its syntax is "find PATH PARAMETERS". A typical usage is along with #xargs to execute a command over all resulting files of find command. For example, we can remove all files starting with "log" within the "/tmp folder: ⚙ $ find /tmp -name log -type f | xargs rm -f Besides, we can use find in combination with #grep to search a word over several files. For example, searching all the files in a folder that contain the word bill: ⚙ $ find PATH -name *.txt | xargs grep -l "Bill" Do you know more usage and pipes with find?

Hey LinkedIn, Tip of the Day: Use grep to Search for Text Within Files The grep command is a powerful tool for searching through files for specific patterns. Whether you're a developer, system administrator, or just a Linux enthusiast, grep can save you a lot of time and effort. Basic Usage: grep 'search_term' filename Example: Suppose you want to find the word "error" in a log file: grep 'error' /var/log/syslog Advanced Usage: Recursive Search: Search for a pattern in all files within a directory and its subdirectories. grep -r 'search_term' /path/to/directory Ignore Case Sensitivity: Search for a pattern case-insensitively. grep -i 'search_term' filename Show Line Numbers: Display the line numbers where the pattern is found. grep -n 'search_term' filename Why Use grep? Quickly locate specific information within large files. Filter and analyze log files efficiently. Automate repetitive search tasks in scripts. Happy searching!

If you're a Linux user, don't miss this amazing tool! way more straightforward than the classic man command with clear examples for using each command which you'll find quite useful especially when you're in a hurry. https://lnkd.in/dEGMcgem #linux #command #tldr

I've just started a new open source project on #GitHub: eternal-db. Motivation: I needed a simple embedded time series database with a full control on a disk space usage, which I could not find in existing solutions like #Kafka or #InfluxDB. https://lnkd.in/dBta64v9 #java #java21 #linux #database #opensource #embedded

Linux gives you power. You can analyze a lot of even unstructured data, such as data from PDF, and make a database out of it. This is why bash is powerful. 😁
