Editing ADB Commands (section)

=== Few bash snippets ===
@Source (https://jonfhancock.com/bash-your-way-to-better-android-development-1169bc3e0424)

=== Using tail -n
//Use tail to remove the first line. Actually two lines. The first one is just a newline. The second is “List of devices attached.”
$ adb devices | tail -n +2

=== Using cut -sf
// Cut the last word and any white space off the end of each line.
$ adb devices | tail -n +2 | cut -sf -1

=== Using xargs -I
// Given the -I option, xargs will perform an action for each line of text that we feed into it.
// We can give the line a variable name to use in commands that xargs can execute.
$ adb devices | tail -n +2 | cut -sf -1 | xargs -I X echo X aw yiss

=== Three options below together
// Will print android version of all connected devices
adb devices | tail -n +2 | cut -sf -1 | xargs -I X adb -s X shell getprop ro.build.version.release  

=== Using alias
-- Example 1 
alias tellMeMore=echo
tellMeMore "hi there"
Output => hi there
-- Example 2
// Define alias
alias apkinstall="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X install -r $1"
// And you can use it later 
apkinstall ~/Downloads/MyAppRelease.apk  // Install an apk on all devices
-- Example 3
alias rmapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X uninstall $1"
rmapp com.example.myapp // Uninstall a package from all devices
-- Example 4
alias clearapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell pm clear $1"
clearapp com.example.myapp  // Clear data on all devices (leave installed)
-- Example 5
alias startintent="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell am start $1"
startintent https://twitter.com/JonFHancock // Launch a deep link on all devices


Setting up your .bash_profile
Finally, to make this all reusable even after rebooting your computer (aliases only last through the current session), we have to add these to your .bash_profile. You might or might not already have a .bash_profile, so let’s make sure we append to it rather than overwriting it. Just open a terminal, and run the following command

touch .bash_profile && open .bash_profile

This will create it if it doesn’t already exist, and open it in a text editor either way. Now just copy and paste all of the aliases into it, save, and close.

alias startintent="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell am start $1"
alias apkinstall="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X install -r $1"
alias rmapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X uninstall $1"
alias clearapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell pm clear $1"
