Use: "lsf remote:path",
|
|
Short: `List directories and objects in remote:path formatted for parsing.`,
|
|
Long: `
|
|
List the contents of the source path (directories and objects) to
|
|
standard output in a form which is easy to parse by scripts. By
|
|
default this will just be the names of the objects and directories,
|
|
one per line. The directories will have a / suffix.
|
|
|
|
Eg
|
|
|
|
$ rclone lsf swift:bucket
|
|

|
|
canole

|
Use the --format option to control what gets listed. By default this
|
|
is just the path, but you can use these parameters to control the
|
|
output:
|
|
|
|
p - path
|
|
s - size
|
|
t - modification time
|
|
h - hash
|
|
i - ID of object
|
|
o - Original ID of underlying object
|
|
m - MimeType of object if known
|
|
e - encrypted name
|
|
T - tier of storage if known, e.g. "Hot" or "Cool"
|
|
|
|
So if you wanted the path, size and modification time, you would use
|
|
--format "pst", or maybe --format "tsp" to put the path last.
|
|
|
|
Eg
|
|
|
|
$ rclone lsf --format "tsp" swift:bucket

|
If you specify "h" in the format you will get the MD5 hash by default,
|
|
use the "--hash" flag to change which hash you want. Note that this
|
|
can be returned as an empty string if it isn't available on the object
|
|
(and for directories), "ERROR" if there was an error reading it from
|
|
the object and "UNSUPPORTED" if that object does not support that hash
|
|
type.
|
|
|
|
For example to emulate the md5sum command you can use
|
|
|
|
rclone lsf -R --hash MD5 --format hp --separator " " --files-only .
|
|
|
|
Eg
|
|
|
|
$ rclone lsf -R --hash MD5 --format hp --separator " " --files-only swift:bucket

(Though "rclone md5sum ." is an easier way of typing this.)
|
|
|
|
By default the separator is ";" this can be changed with the
|
|
--separator flag. Note that separators aren't escaped in the path so
|
|
putting it last is a good strategy.
|
|
|
|
Eg
|
|
|
|
$ rclone lsf --separator "," --format "tshp" swift:bucket
|
|

You can output in CSV standard format. This will escape things in "
|
|
if they contain ,
|
|
|
|
Eg
|
|
|
|
$ rclone lsf --csv --files-only --format ps remote:path
|
|
test.log,22355
|
|
test.sh,449
|
|
"this file contains a comma, in the file name.txt",6
|
|
|
|
Note that the --absolute parameter is useful for making lists of files
|
|
to pass to an rclone copy with the --files-from-raw flag.
|
|
|
|
For example to find all the files modified within one day and copy
|
|
those only (without traversing the whole directory structure):
|
|
|
|
rclone lsf --absolute --files-only --max-age 1d /path/to/local > new_files
|
|
rclone copy --files-from-raw new_files /path/to/local remote:path
