General question about scripts/batch files - Sprint HTC EVO 4G LTE

I love command line interface. Two years ago, when I got my OG EVO on launch day, the only way to root was through toast's cryptic instructions here and here. Even for an old DOS guy like me, they were daunting as an Android newb, but after several days of poking around and reading everything I could find, the process went smoothly. Fast-forward to today.....I'm ready to root my new EVO LTE and would love to do it myself. I have the SDK installed on both my work and home computers and feel like all I need to do is execute the commands contained in the one-click solution posted by zedomax.
Code:
@echo Rooting...
@adb wait-for-device
@echo Start Rooting...
@adb shell mv /data/local/tmp /data/local/tmp.bak
@adb shell ln -s /data /data/local/tmp
@adb reboot
@echo reboot #1 - DO NOT DISCONNECT YOUR DEVICE!
@PING 1.1.1.1 -n 1 -w 9000 >NUL
@adb wait-for-device
@adb shell "echo \"ro.kernel.qemu=1\" > /data/local.prop"
@adb reboot
@echo reboot #2 - DO NOT DISCONNECT YOUR DEVICE!
@PING 1.1.1.1 -n 1 -w 9000 >NUL
@adb wait-for-device
@adb remount
@PING 1.1.1.1 -n 1 -w 3000 >NUL
@adb push su /system/bin/su
@adb shell "chown root.shell /system/bin/su"
@adb shell "chmod 06755 /system/bin/su"
@adb shell "rm /system/xbin/su"
@adb shell "ln -s /system/bin/su /system/xbin/su"
@adb push Superuser.apk /system/app/.
@adb shell rm /data/local.prop
@adb shell rm /data/local/tmp
@adb shell mv /data/local/tmp.bak /data/local/tmp
@adb push busybox /data/local/tmp/.
@adb shell "chmod 755 /data/local/tmp/busybox"
@adb shell "/data/local/tmp/busybox mount -o remount,rw /system"
@adb shell "dd if=/data/local/tmp/busybox of=/system/xbin/busybox"
@adb shell "chown root.shell /system/xbin/busybox"
@adb shell "chmod 04755 /system/xbin/busybox"
@adb shell "/system/xbin/busybox --install -s /system/xbin"
@adb shell "rm -r /data/local/tmp/busybox"
@echo rebooting
@adb reboot
@echo All Done rooting Evo 4G LTE, check out OneXRoot.com for more cool stuff like ROMs, hacks, tips, and more!
So here's my question, will running each of these commands (minus the @echo and "wait-for-device" ones), accomplish the same thing as executing the batch file or does the automated nature of the script add something else to the process??? Obviously, I know that I need to put the busybox and su files in the appropriate folder, but other than that, is there something else I would need to do?
Thanks for any input!
