Fellow Cygwin fans,
I'm trying to keep the many directories with "OneDrive" in the
pathname out of the locatedb file, as I don't care to see them in
locate's output, nor bloat the locatedb file.
I'd appreciate any insight into the prunepaths option for the test
case below, (Line 10,) and how to tell prunepaths to ignore paths with
spaces so that the paths in Lines 5 and 6 below will not be included
in the locatedb file.
1. Versions:
2. updatedb (GNU findutils) 4.8.0
3. CYGWIN_NT-10.0 3.2.0(0.340/5/3) 2021-03-29 08:42 x86_64 Cygwin
4. Unfortunately, on this Windows 10 PC there are 650 unique
directory paths with "OneDrive" in them, and these three are the most
numerous:
5. /cygdrive/c/Users/corporatedroid/OneDrive - FoobarCorp/
6.
/home/c_users_corporatedroid/corporatedroid/OneDrive - FoobarCorp/
7.
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/FoobarCorp/
8. With the one-liner below, we create a small locatedb file
(/var/locatedb_prune_test) and specify that prunepaths omit the
'/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/ListSync'
subdirectory:
9. ==================================
10. F=/var/locatedb_prune_test; echo ; updatedb
--localpaths='/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive'
--output=${F} --prunepaths='/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/ListSync'
; ls -l ${F}
11. -rw-r--r-- 1 corporatedroid Domain Users 26280 Dec
9 06:22 /var/locatedb_prune_test
12. ==================================
13. Here, we see that the path ending with 'ListSync'
incorrectly appears in the /var/locatedb_prune_test output despite the
prunepaths option in line 10:
14. ==================================
15. F=/var/locatedb_prune_test;locate -d${F} 'ListSync'|cat -n|tail -3
16. 33
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/logs/ListSync/Business1/Nucleus-2021-12-09.1317.15440.1.odl
17. 34
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/logs/ListSync/Business1/microsoftNucleusTelemetryCache.otc
18. 35
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/logs/ListSync/Business1/telemetry-dll-ramp-value.txt
19. ==================================
Any ideas appreciated.

Search:
https://www.mail-archive.com/search?l=cygwin%40cygwin.com&q=updatedb
e.g.
https://www.mail-archive.com/cygwin@cygwin.com/msg146142.html
for operational hints.
For info:
$ info updatedb
/--prunepaths=
$ info -- find -regex
The option --prunepaths takes an argument containing a space separated
list of find ... -regex (Basic) REs which match *complete* directory
paths to prune from: if absolute, these start with / and end without
one; try an argument list where USER=corporatedroid and CORP=FoobarCorp
like for example:
"/.*[Uu]sers.*$USER.*OneDrive.* /.*[Uu]sers.*$USER.*$CORP.*
/.*[Uu]sers.*$USER.*ListSync.* /[^[:space:]]*"
or even:
"/.*[Uu]sers.*$USER.*\(OneDrive\|$CORP\|ListSync\).* /[^[:space:]]*"
You may want to be sure those directories are mounted as --localpaths
rather than --netpaths which have additional requirements:
$ cat /proc/filesystems
vfat
exfat
ntfs
refs
nodev smbfs
nodev nfs
nodev netapp
iso9660
udf
nodev csc-cache
nodev unixfs
nodev mvfs
nodev cifs
nodev nwfs
nodev ncfsd
nodev afs
nodev prlfs
$ mount
C:/cygwin/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,noumount,auto)
...
[Please don't post with extra spaces, step nos (use text refs instead),
or long command lines, as many devs and some users read with mono fonts
and short wrap margins e.g 72, 80.
You could use updatedb env vars instead of options for readability.]

Brian,
Thanks very much for the prunepaths regexes, the /proc/filesystems output,
mount command, and info and man command lines, and the suggestions for
better posting.
