A while back I posted very excitedly about an update to the du binary:
https://community.jamf.com/t5/jamf-pro/gnu-new-du-binary-option-in-macos-12-monterey/td-p/252266
I forgot to post that I actually used it for something...
We pushed Druva into production earlier this year for all clients (macOS & Windows). uses Druva internally & in my opinion it is the gold standard for cloud backup: https://www.druva.com
Before doing so, however, we wanted to figure out how much data lived in everyone's home folder & the sub-folders, so, of course I made a multi-line Jamf Pro extension attribute...
#!/bin/sh
# macOS version check
if [ "$(/usr/bin/sw_vers -productVersion | /usr/bin/awk -F '.' '{print $1}')" -ge 12 ]
then
byteblk='--si'
else
byteblk='-h'
fi
# collect home folder size (collects size of dot files but excludes from display)
crntusr="$(/usr/bin/stat -f %Su /dev/console)"
dscldir="$(/usr/bin/dscl -plist . read /Users/"$crntusr" NFSHomeDirectory)"
homedir="$(/usr/libexec/PlistBuddy -c "print dsAttrTypeStandard\:NFSHomeDirectory:0" /dev/stdin <<< "$dscldir")"
homesiz="$(/usr/bin/du -d 1 "$byteblk" "$homedir" | /usr/bin/awk '!/\/\./{print}' | /usr/bin/sort -k 2)"
echo "<result>$homesiz</result>"
(ps. Why was this necessary? Because "Home Folder Size" in Settings > Computer Management - Management Framework > Inventory Collection is about as useless as betting against the Harlem Globetrotters...)
The output in Jamf looks like this:
I then used the Jamf API & a little shell fu to calculate totals (there was some additional screwing around with bc & in spreadsheets after this 😐 :
#!/bin/zsh
# set -x
# trap read debug
apiuser=''
apipswd=''
jamfurl=''
eastrng=''
echo 'Username,Users,Applications,Desktop,Documents,Downloads,Library,Movies,Music,Pictures,Public' > ~/Desktop/sizes.csv
jamfids()

apidata=$(/usr/bin/curl -sS -X GET -H 'accept: application/xml' -u "$apiuser:$apipswd" "$jamfurl/$1")
arrsize=$(echo "$apidata" | /usr/bin/xmllint --xpath "//size/text()" -)
for ((i=0;i<=$arrsize;i++)) { echo "$apidata" | /usr/bin/xmllint --xpath "concat(//$2[$i]/id/text(),' ')" - ; }
}
/bin/sleep 1
arr=($(jamfids computers computer))
for i in "${arr[@]}"
do

done
Sample of .csv output:
Enjoy!
