I am trying to get free sdcard space with adb command, but I could not able to achieve. Any suggestions how to get the sdcard space.
df, as with any Linux distro. Not all Android devices may have it, but it usually seems to be available.
df: Disk space details.
adb shell df
du: Disk space used by the specified files and subdirectories.
adb shell du
df -h: Disk space details in KB/MB format.
adb shell df -h
du -h: Disk space used by the specified files and subdirectories in KB/MB format.
adb shell du -h
For specific folder desk space details.
adb shell df /system
For specific folder and sub-directories desk space details
adb shell du /system
df -h to find disk usage and to find big files:
du -a <the_dir> | sort -n -r | head -n 20
