I have forgotten how to use find, I use it so few times. So instead of
learning again, when I need to use it, I use chatgpt to concoct the line
for me :-P
The other day I wanted to search a machine to find files created between
certain dates:
Laicolasse:~ # time find / -type d -newermt "2025-07-28" \
! -newermt "2025-07-31" 2>/dev/null | tee busqueda
^C
real 26m14.066s
user 0m3.725s
sys 1m5.634s
Laicolasse:~ #
Took way too long for a laptop with M2 disk. It was faster on other
machines.
Turned out that an automount was happening of an external nfs mount on
"/mnt/nfs/Isengard/xfsRaid/", and that raid is big and slow, the search
took for ever.
I did not want to do a refresher course on "find" again.
With the aid of chatgpt I came with:
# find / \( -path /mnt/nfs/Isengard/xfsRaid/ \) -prune \
-o -type d -newermt "2025-07-28" ! -newermt "2025-07-31" \
2>/dev/null | tee busqueda
But did not work, the directory was mounted again and scanned. I then
deleted the automount line from fstab:
#Isengard.valinor:/data/xfsRaid/ /mnt/nfs/Isengard/xfsRaid \
nfs4 noauto,nofail,x-systemd.automount,\
x-systemd.idle-timeout=300,_netdev,user,users,lazytime 0 0
But did not work because systemd has a memory (automatic mount units)
and still automounted the directory.
So what did I do?
Stop the network!
Brute force approach.
In retrospect, I should have used:
Laicolasse:~ # time find / \( -path /mnt/nfs/Isengard/ \) \
-prune -o -type d -newermt "2025-07-28" ! -newermt \
"2025-07-31" 2>/dev/null | tee busqueda
...
real 0m3.035s
user 0m0.836s
sys 0m2.180s
Laicolasse:~ #
--
Cheers, Carlos.
