Use the <code>-s</code> option BEFORE the command to specify the device, for example:

Another alternative would be to set environment variable ANDROID_SERIAL to the relevant serial, here assuming you are using Windows:
<pre><code>set ANDROID_SERIAL=7f1c864e

&quot;7f1c864e&quot;

Then you can use <code>adb.exe shell</code> without any issues.

Create a Bash (tools.sh) to select a serial from devices (or emulator):

<pre><code>clear;

echo " ADB DEVICES";
echo "====================================================================================================";
echo "";

adb_devices=( $(adb devices | grep -v devices | grep device | cut -f 1)#$(adb devices | grep -v devices | grep device | cut -f 2) );

 case "${selection}" in
 0)
 // Call Main Menu function fxMenu;
 *) 
 device="$(echo ${adb_devices[$((selection-1))]} | cut -f1 -d#)";
 // Call Main Menu function fxMenu;
 esac
fi
</code></pre>

Then in another option can use <code>adb -s</code> (global option -s use device with given serial number that overrides $ANDROID_SERIAL):

<pre><code>adb -s ${device} &lt;command&gt;
</code></pre>

I tested this code on MacOS terminal, but I think it can be used on windows across Git Bash Terminal.

Also remember configure environmental variables and Android SDK paths on <code>.bash_profile</code> file:

<pre><code>export ANDROID_HOME="/usr/local/opt/android-sdk/"
export PATH="$ANDROID_HOME/platform-tools:$PATH"
export PATH="$ANDROID_HOME/tools:$PATH"
</code></pre>

For the sake of convenience, one can create run configurations, which set the <code>ANDROID_SERIAL</code>:
<a href="https://i.stack.imgur.com/syUOE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/syUOE.png" alt="screenshot" /></a>
Where the <code>adb_wifi.bat</code> may look alike (only positional argument <code>%1%</code> and <code>&quot;$1&quot;</code> may differ):
<pre><code>adb tcpip 5555
adb connect %1%:5555
echo &quot;disconnect the USB cable now&quot;
</code></pre>
The advance is, that <code>adb</code> will pick up the current <code>ANDROID_SERIAL</code>. 
In shell script also <code>ANDROID_SERIAL=xyz adb shell</code> should work.
This statement is not necessarily wrong:
<pre><code>-s SERIAL use device with given serial (overrides $ANDROID_SERIAL)
</code></pre>
But one can as well just change the <code>ANDROID_SERIAL</code> right before running the <code>adb</code> command.

<pre><code>$ adb --help
