Puppy Linux Discussion Forum

Edit: changed the post subject from: What is Puppy's boot file location variable?

The object was to find the boot file directory, here is the code I used to do it. The find command looks for an exact file name with an exact file size, so it should be pretty accurate. If there's a better method, please post.

#calculate file size in bites /1048576
finddir=$(find /mnt/home/ -type f -name "puppy_fossapup64_9.5.sfs" -size 487M)
  echo "$finddir"
 pupdir=$(dirname "$finddir")
  echo "$pupdir"

Thanks

Not sure if this will help but environment variables are shown via this terminal command: 'printenv'

Some/Much of what you may want could be in a boot log.

Hope this is helpful.

@Clarity

Good info to know, but didn't find any that pointed to the directory

Thanks

@wizard You can find the information you need in /etc/rc.d/PUPSTATE. Just source this file and use its variables. In my case $PSUBDIR holds the requested directory (may depend on your boot parameters). The variable $PUPSFS may be more suited, but you would need to extract the directory from it.
If $PSUBDIR is what you are looking for, then try

source /etc/rc.d/PUPSTATE
pupdir="/mnt/home$PSUBDIR"
echo  "$pupdir"

If you need the path for your main sfs file:

source /etc/rc.d/PUPSTATE
pupfile="/mnt/home/${PUPSFS#*/}"
echo "$pupfile"

YES!

# geany /etc/rc.d/PUPSTATE

@MochiMoppel

Used your code and works perfect. Much better than mine since it will never have to be edited for a change in file size.
