Effortlessly Zip All Log Files in Linux

As a newcomer to Linux, working with files and directories can seem intimidating—especially when it comes to batch processing files. In this post, we will address a common task: zipping up all log files in a designated directory while ensuring that the original log files are deleted afterward. This way, you keep your workspace tidy without losing valuable log data.

The Problem: Zipping Log Files

When trying to zip all .log files in a Linux directory, you might want to compress each log file into its own .zip file while removing the uncompressed version. If you are just starting out with for loops and command-line tasks, syntax errors can easily lead to unexpected results. Our reader encountered an issue where hidden files were unintentionally zipped up due to a syntax mishap in their original command.

Understanding the Desired Outcome

The goal is to achieve the following:

Create a separate .zip file for each .log file.

Retain the files in their original directory.

Delete the original .log files after zipping them.

The Solution: Correcting the Command

To address the issue, let's break down the correct command for zipping the log files:

Explanation of the Command

SSH into the Server:

The command starts with ssh user@ SERVER which connects you to the desired server.

For Loop Setup:

for i in *.log; do iterates through each log file in the directory.

Zipping the Files:

echo zip -m "${i/.log/.zip}" "${i}"; constructs the zipping command for each log file:

${i/.log/.zip} changes the .log extension to .zip.

This ensures that each log file is zipped correctly.

Feedback Before Execution:

The echo command allows you to preview the command that will be executed. This is a safety measure to confirm you have the correct files before zipping them.

Removing the Original Log Files:

The -m flag in the zip command compresses the file and removes the original log file in one go.

Final Step

If the output seems correct and you’re satisfied with the preview of the zip commands, simply remove the echo from the command to execute it for real:
