change owner of ghidra project

ghrab.sh

#!/bin/bash
#
# grab ownership of ghidra project specified in arg1 or current dir if absent
#
#	- looks for the first <projectname>.gpr file
#	- modifies owner name <projectname>/project.prp
#
# example : ./ghrab.sh ~/RE/coolstuff


# Discussed in https://github.com/NationalSecurityAgency/ghidra/issues/5507

# " if you create a project under your current username then try to give it to someone else,
# or otherwise just copy it to another machine or VM with a different user name you will get an error:
# "..Failure to open project ... NoOwnerException: Project is not owned by xxx.."
#
# obvious caveat : this is a bad idea if permissions are not appropriate on some of the project files.



u=$(whoami)

# use arg1 if defined, else pwd
base_dir="${1:-$(pwd)}"


gpr_file=$(find "$base_dir" -name "*.gpr" -printf %f -quit)
if [ -z "$gpr_file" ]; then
	echo "no .gpr file found !"
	exit 1
fi

prj_name=${gpr_file%.gpr}
prp_file="$base_dir/${prj_name}.rep/project.prp"
if ! [ -f "$prp_file" ]; then
	echo "$prp_file" not found !

sed "$prp_file" -i -e "/OWNER/s/VALUE=\"[^\"]\+/VALUE=\"$u/"

Thanks for this script! It was handy and it worked to import a project to which I don't have an exported archive.

I fixed the warnings from shellcheck if you are interested (only one of them is likely to produce undesired results):

$ shellcheck ghgrab.sh

In ghgrab.sh line 21:
u=whoami
^------^ SC2006 (style): Use $(...) notation instead of legacy backticks ....

Did you mean:
u=$(whoami)

In ghgrab.sh line 27:
gpr_file=$(find "$base_dir" -name *.gpr -printf %f -quit)
^---^ SC2061 (warning): Quote the parameter to -name so the shell won't interpret it.
^-- SC2035 (info): Use ./glob or -- glob so names with dashes won't become options.

Change line 21 to u=$(whoami)
Change line 27 to gpr_file=$(find "$base_dir" -name "*.gpr" -printf %f -quit)

good points, thanks! Updated

Nice, I switched PC's and this is a lifesaver, although I did it just manually.

thank you for this. Had to make some changes to make it work for macos:

gpr_path=$(find "$base_dir" -name "*.gpr" -print -quit)
if [ -z "$gpr_path" ]; then
	echo "no .gpr file found !"
	exit 1
fi
gpr_file=$(basename "$gpr_path")
gpr_dir=$(dirname "$gpr_path")

prj_name=${gpr_file%.gpr}
prp_file="$gpr_dir/${prj_name}.rep/project.prp"
if ! [ -f "$prp_file" ]; then
	echo "$prp_file" not found !
	exit 1
fi

echo Found ghidra project: "$prj_name"
sed -i '' -E "/OWNER/s/VALUE=\"[^\"]+/VALUE=\"$u/" "$prp_file"

I had an assortment of projects in a directory and the script only appeared to work on one at a time, so I updated it to the following which seemed to work for me.

#!/bin/bash

u=$(whoami)

# use arg1 if defined, else pwd
base_dir="${1:-$(pwd)}"

for file in "$base_dir/*.gpr"; do
	if [ -f "$file" ]; then
		prj_name=${file%.gpr}
		prp_file="$base_dir/${prj_name}.rep/project.prp"
		echo "Processing $prj_name"
		sed "$prp_file" -i -e "/OWNER/s/VALUE=\"[^\"]\+/VALUE=\"$u/"
	fi
done

Interesting, that's something I haven't encountered here (if I'm looking at different fw / sw versions I'll typically load them all in the same ghidra project, makes it easier to share data between them).

for file in *.gpr; do
....

So your version is hardcoded to look in current dir ? why not for file in "$base_dir/*.gpr" (untested) ?

That wasn't actually intentional, I just threw it together very quickly and missed that.
