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
${PAL:DRIVELETTER}
and numerous other things.
The bash "Definitions" does mention explicitly:
name
A word consisting solely of letters, numbers, and underscores, and beginning with a letter or underscore.
Names are used as shell variable and function names.
Also referred to as an identifier.
So your variable name PAL:DRIVELETTER is actually invalid.
You need to extract it from the ' env
' output, as proposed in this answer :
pal_driveletter=$(env |grep "^PAL:DRIVELETTER=" | cut -d= -f2-)
