If you have installed necessary commands like VI editor on your android linux, you can go ahead with shell scripting. Here I have created simple linux script to backup all installed applications .apk files on to sdcard.
First of all whatever applications I installed through google play, I found them at "/data/apps"
|All installed .apk goes to /data/app|
So I have written simple shell script as below to backup those apk to sdcard, nothinig Great very simple commands!!
Notice #!/system/bin/sh as .. our "sh" is located at /system/bin/
cp *.apk /sdcard/apkbackup
After creating script as usual you can give permissions to script file : chmod 777 backupapk.sh
now execute script as : sh backupapk.sh
Thats it all your installed apk will be backed up on storage card!!
|All .apk files are copied to specified location|
This is just introduction to shell scripting on android linux, will post more scripts and interesting things as i explorer.
