// Help describes the common help for all the list commands
var Help = `
Any of the filtering options can be applied to this commmand.
There are several related list commands
* ` + "`ls`" + ` to list size and path of objects only
* ` + "`lsl`" + ` to list modification time, size and path of objects only
* ` + "`lsd`" + ` to list directories only
* ` + "`lsf`" + ` to list objects and directories in easy to parse format
* ` + "`lsjson`" + ` to list objects and directories in JSON format
` + "`ls`,`lsl`,`lsd`" + ` are designed to be human readable.
` + "`lsf`" + ` is designed to be human and machine readable.
` + "`lsjson`" + ` is designed to be machine readable.
Note that ` + "`ls`,`lsl`,`lsd`" + ` all recurse by default - use "--max-depth 1" to stop the recursion.
The other list commands ` + "`lsf`,`lsjson`" + ` do not recurse by default - use "-R" to make them recurse.

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.
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
So if you wanted the path, size and modification time, you would use
--format "pst", or maybe --format "tsp" to put the path last.
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.
