How to write adb commands into a bat

I have my laptop connected to an android phone.
I am doing a task many times, so I wish to write a .bat file to run the commands automatically.
adb shell
cd /sdcard/speech
rm -f *
The bat file only executed adb shell, the rest codes were not executed.
I guess because the it entered the android device so the commands did not run as usual.
One solution was adb shell rm -f -r /sdcard/speech/*
What if there are more and more complicated commands?
Is there a way to do it ?

You can do your job with adb shell "cd /sdcard/speech; rm -f *".
For more complicated jobs, you can put all the commands in a Linux shell script, use adb push command to push the script to your Android device, and run the script using adb shell.
For example, put all the commands in run.sh, then issue:
adb push run.sh /data/local/tmp
adb shell "chmod +x /data/local/tmp/run.sh"
After this you can run your jobs with:
adb shell "/data/local/tmp/run.sh"
You can include the above line in a .bat file.

How to pass multiple commands through adb shell using python script without exiting the shell

I am trying to access adb shell of an android device and pass multiple commands such as
adb root
adb shell
cd /data/local/tmp
export PATH =/data/local/tmp:$PATH
export PATH =/data/local/tmp/testcases:$PATH
sh ./runltp -p -l 1213reportipc.log -d /data/local/tmp/LTP13/tmp -f ipc1q
exit
While I am able to do this manually using adb shell, I am unable to do this via a Python script since as soon script execution encounters 'adb shell' command it spawns a new internal shell and rest of the commands are not executed.
Can anyone please help me with this.

Use a text editor such as sublime or something, write your full adb script using subprocess to send commands and run it while your laptop is connected to your phone and USB debugging is switched on.
import subprocess
subprocess.call("adb shell <your command here>", shell = True)
subprocess.call("adb shell tap 172 3241", shell = True) -- example
etc, just put your commands after the 'adb shell' and run the python script. This should type all your commands into the adb shell. You should even be able to enter commands such as
subprocess.call("adb kill-server", shell=True)
or subprocess.call("adb root", shell=True)

How can I pass executable command as argument to adb shell?

I am getting error while executing the below command:
$ sudo adb shell ping `cat /data/my_address.pst`
Where my_adress.pst file contains the ip address.
But the same command works fine when executed from the shell.
$ sudo adb shell
$ ping `cat /data/my_address.pst`
How can i pass executable commands like this? please throw some light on this.
Thanks.

Escape the ` so it is not interpreted by the shell.
adb shell ping \`cat /data/my_address.pst\`

Your cat /data/my_address.pst command gets executed by local shell so you need to escape the backticks or single quote the whole command. Also you do not need sudo and use of $() is preferable over backticks:
adb shell 'ping $(cat /data/my_address.pst)'

chmod android file system from script

I'm using an Android-x86 vm running in vmware fusion for some testing purposes. I am pushing files to it via adb push, however, every time I uninstall and reinstall the app, I have to execute the following:
adb shell
su
chmod 777 /my/path
exit
exit
I need to be able to script out this entire process but I'm not sure how I can manage the chmod process via some sort of script. I tried doing something like
adb shell am chmod 777 /my/path
But that doesn't work. I thought it would because I can do
adb shell am start ...
I also tried:
adb shell "su && chmod 777 /my/path && exit && exit"
which actually works, but doesn't exit the shell process. So any advice is much appreciated.

You can pass commands to adb shell, as you mentioned, though it works better if you surround the command in quotes.
Likewise, you can pass commands to the 'su' command using the -c argument. Add all of this together and it should do what you want in a nice one-liner!
adb shell "su -c 'chmod 777 /my/path'"

Launch a script as root through ADB

I have created a script to mount partitions and do some stuff in my Android system. I saved the script as install.sh in the /bin folder of Android.
I want to call the script from ADB, which is itself called from a batch file on Windows, but it needs to be executed as root.
The first solution I tried was to call the script using
adb shell "su -c sh /bin/script.sh"
but it does not work as it gives me a shell access (with root permissions), but nothing is executed.
I also tried to call
adb root "sh /bin/script.sh"
but I got the following error
adbd cannot run as root in production builds
I then tried to write
su -c "command"
for all the commands which need a root access in my script, but I have the same problem.
When I run the script I only obtain a root shell and nothing is executed.
If I use the first solution by hand (e.g. I call adb shell su, then my script), it works. However the whole point is to automate the process, so that adb shell can be called from another script.
Do you have any idea of how I could achieve this ?
Thanks !

This works for me:
Create myscript.bat and put into it (note the single quotes around the commands to be executed in superuser mode):
adb shell "su -c 'command1; command2; command3'"
then run myscript.bat from a DOS shell.
Note: it doesn't appear that the the DOS line continuation character (^) works in this situation. In other words, the following doesn't work for me:
adb shell "su -c '^
command1; ^
command2; ^
command3'"
This results in "Syntax error: Unterminated quoted string"

This works :
adb shell echo command which needs root privileges \| su
If you need redirection:
adb shell echo 'echo anytext > /data/data/aforbiddenfolder/file' \| su
For "copying" a local file to an android path needing root privileges (but alocalfile must not contain '):
cat alocalfile | adb shell echo "echo '`cat`' > /data/data/aforbiddenfolder/file" \| su
If you have a better way (even for su versions which don't have -c), I am interested.

This works for me:
adb shell "su -c ./data/local/tcpdump-arm -s 0 -v -w /data/local/appxpress_dump.pcap"

I am not sure if I provided a solution or asked for a better one.
I wanted to run some 200 command in batch mode to be sent to adb
I followed this approach
adb shell "su -c command ; "
adb shell "su -c command ; "
adb shell "su -c command ; "
adb shell "su -c command ; "
and I saved them in a batch file
This command
adb shell "su -c 'command1; command2; command3'"
will not work beyond a certain max size . It did not work
error: service name too long

but it does not work as it gives me a shell access (with root permissions), but nothing is executed.
How do you know that you are given root permissions? I assume you are attempting to execute the script on a device? Has your device been rooted?
You may need to give execute permissions via chmod to the file.
chmod ugo=rwx /bin/script.sh

It appears that I was using a very simple version of su which did not accept the -c argument.
I copied another su which did work. AndyD is totally right though, so I am accepting his answer instead of mine :)
