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.]
