im trying to create bash script to install split APKs manually with adb shell that requires to get session id using the command bellow

command

SESSION='pm install-create -S 42211368'

this will output something like : Success: created install session [547376362]

547376362 will be the session ID

I want to pass 547376362 into SESSION Variable

sh < pm install-write -S 24628703 ${SESSION} 0 /sdcard/YTAPKM/base.apk

so result shall be "sh < pm install-write -S 24628703 547376362 0 /sdcard/YTAPKM/base.apk"

CodePudding user response：

grep is sufficient for this.

SESSION=$(pm install-create -S 42211368 | grep -oE '[0-9] ')
sh < pm install-write -S 24628703 ${SESSION} 0 /sdcard/YTAPKM/base.apk

To explain what's happening a bit:

• grep -E uses "extended" regular expressions (easier to work with)
• grep -o outputs only the matching part, the integer in this case
• SESSION=$(some_cmd) stores the stdout from some_cmd to the variable SESSION, and allows for pipes and such too
