I am trying to configure my windows portable git bash shell. When I execute env I get:

ANT_HOME=C:\Program Files\WinAnt
PORTABLEAPPS.COMVIDEOS:FORWARDSLASH=H:/Documents/Videos
VBOX_INSTALL_PATH=C:\Program Files\Oracle\VirtualBox\
PORTABLEAPPS.COMLOCALEWINNAME=LANG_ENGLISH
PAL:LASTPORTABLEAPPSBASEDIR:DOUBLEBACKSLASH=H:
PAL:DRIVELETTER=H   **** this is the variable I am after  ******
PAL:APPDIR=H:\PortableApps\GitPortable\App
TEMP=/tmp

The variable I am trying to reference is PAL:DRIVELETTER=H. I want to use this set my path in my .bash_profile script. This is all on a USB stick and the drive letter will of course change from time to time.

I have tried echoing:

$PAL:DRIVELETTER
${PAL:DRIVELETTER}

and numerous other things.

The problem is that PAL:DRIVELETTER is not a valid variable name in bash. Only alphanumeric and underscore are allowed. From the bash man page:

DEFINITIONS

...

name A word consisting only of alphanumeric characters and underscores, and beginning with an alphabetic character or an underscore. Also referred to as an identifier.

To get the value:

pal_driveletter=$(env |grep "^PAL:DRIVELETTER=" | cut -d= -f2-)
