# Synchronizing Git Submodules Modifying URLs
Sometimes it is not possible to access submodules as they were registered. Solution is here:
```{.bash}
#!/bin/bash
NUMARGS=$#
SCRIPT=`basename ${BASH_SOURCE[0]}`
GREEN='\033[1;32m'
NC='\033[0m'
function HELP {
echo -e "${GREEN}Usage${NC}: ${SCRIPT} server-name ip-address timeout-sec"
exit 1
}
if [ $NUMARGS -ne 3 ]; then
HELP
fi
name=$1
address=$2
timeout=$3
rc=1
while [ $rc -ne 0 ]; do
find ./ -type f \( -name .gitmodules \) -print0 | xargs -0 sed -i "s/$name/$address/g"
git submodule sync --recursive
timeout $timeout git submodule update --init --recursive
rc=$?
done
echo -e "${GREEN}All done.${NC}"
```
