Efficiently Pulling Multiple Files with ADB

Efficiently Pulling Multiple Files with ADB

22 April 2024 Stephan Petzl Leave a comment Tech-Help

Working with Android’s ADB (Android Debug Bridge) can sometimes be a bit of a challenge when it comes to transferring multiple files from a device. This article will guide you through the process of pulling multiple files using ADB in a way that is both efficient and effective.

Using ADB to Pull Multiple Files

ADB doesn’t support wildcards natively when pulling files, which can be inconvenient if you’re trying to transfer numerous files that follow a specific naming pattern. However, with a little ingenuity and command line magic, we can easily accomplish this task.

Method 1: Using xargs and adb shell ls

This method involves using the adb shell ls command, which does accept wildcards, in combination with xargs to pull files matching a specific pattern.

Here’s how to do it:

        
# Using a relative path
adb shell 'ls sdcard/gps*.trace' | tr -d '\r' | xargs -n1 adb pull

# Using an absolute path 
adb shell 'ls /sdcard/*.txt' | tr -d '\r' | sed -e 's/^\/\///' | xargs -n1 adb pull
        
    

Method 2: Pulling a Directory

If all files are in a single directory, you can pull the entire directory, and ADB will recursively transfer all files within it.

        
adb pull /sdcard/gpsTraces/ .
        
    

This approach is straightforward and doesn’t require additional processing of the file list.

Method 3: Using find Instead of ls

To avoid potential issues with parsing the output of ls, we can use the find command:

        
adb shell 'find /sdcard/ -name "gps*.trace" -print0' | xargs -0 -n 1 adb pull
        
    

This method is more robust and handles filenames with spaces or special characters more gracefully.
