On macOS machines, this script finds orphaned server mounts in /Volumes and removes them. The presence of orphaned mounts can break links to files in Adobe Creative Suite documents and cause other annoyances. Some people in my environment had dozens of them. If you're having issues like this, run this script regularly with a launchdaemon.

#!/bin/bash

# Find directories in /Volumes with .DS_Store files
# See if each directory with a .DS_Store file is currently mounted
# If it is, skip it. If it's not, it's an orphaned mount, so increment the counter

# Fail on undefined variables, since we're running "rm" commands
set -u

orphanCount=0
OIFS="$IFS"
IFS=$'\n'

results=$(/usr/bin/find /Volumes -mindepth 2 -maxdepth 2 -name ".DS_Store")
for ds_store in ${results}
do
share=$(echo ${ds_store}|awk 'BEGIN {FS="/"}; {print $3}')
mountstring=$(mount | grep "${share} (")
if [ -z "${mountstring}" ]; then
let orphanCount=orphanCount+1
rm "${ds_store}"
fi
done

# If /Volumes itself has a .DS_Store, decrement the result by 1 so it's an accurate count
# Commented out because adding -mindepth 2 to the find command ignores /Volumes/.DS_Store
# making this bit unnecessary
#if [ -f "/Volumes/.DS_Store" ];
#then
#let orphanCount=orphanCount-1
#fi

# Now we know the orphans are empty, so let's delete them
/usr/bin/find /Volumes -maxdepth 1 -empty -exec /bin/rmdir {} \;

IFS="$OIFS"

# Report the results
echo "${orphanCount} orphaned mounts found and removed."
