6.2.8.6 ls

List files and vaults.

Purpose

The ls command displays information about Exascale files and vaults.

Syntax

ls [ filename [ filename ] ... ] [ -l ] [ --detail ] [ --attributes attribute[,attribute] ... ] 
     [ --filter filter[,filter] ... ] [ --sort [-]attribute[,[-]attribute] ... ] 
     [ --count value ] [ -t ]

Command Options

The options for the ls command are:

• filename: A file or vault name that you want to display information for. Vault names are preceded with the @ symbol. The asterisk (*) can be used for wildcard searches. If not specified, then information is displayed about all files or vaults in the current level of the ESCLI file hierarchy.

• -l: Returns output in a long, tabular form.

• --detail: Lists all attributes in a detailed form.

• --attributes: Lists the specific attributes to display.

• --filter: Used to specify conditions for filtering the list output.

• --sort: Used to sort the output using the specified attributes.

• --count: Specifies the maximum number of results to report.

• -t: Sorts files or vaults by ascending creation time.

Usage Notes

Note the following information when using this command:

• Filter conditions are specified as: <attribute><operator><value>.

  Attributes can be file attributes, or vault attributes with the vault. prefix.

  The allowed operators are =, !=, >=, <=, >, and <.

  Multiple comma-separated filter conditions are combined using AND logic.

  Dates can be specified using the following formats:

  • yyyy-MM-dd''T''HH:mm:ss
  • yyyy-MM-dd (Time is assumed to be 00:00 AM)
  • HH:mm:ss (Date is assumed to be today)

  A date can also be followed by a timezone specification.

  File sizes can be specified using suffixes K, KB, M, MB, G, GB, T, TB. The suffix is not case-sensitive.

  For example, the following filter only includes files created after noon today and with a size greater than 10 megabytes:

  --filter creationTime>12:00:00,size>10M

• Sorting attributes are specified as: [-]attribute. Multiple sort attributes are comma-delimited. The default sort order is ascending. For descending sort order, prefix the attribute name with -.

  For example, use the following to primarily sort by name in descending order, and use creation time in ascending order to further sort entries with the same name:

  --sort -name,createTime

Examples

y 
z1 
z2

Example 6-90 Display File Information in a Long Format

If you use the -l option, the output includes additional information about each file or vault.

@MYDATA/> ls -l
Total 5
