Update the access and modification times of each <file> to the current time. Each <file> argument that does not exist is created empty.

Each <file> is of the form

[<scheme>://][[<user>@@]<host>[:<port>]]<path> ...

For scheme ‘hdfs://’ it calls function ‘evl_hdfs_touch’, which is by default ‘hdfs dfs -touchz’.

For scheme ‘sftp://’ it calls function ‘evl_sftp_touch’.

  1. Simple usage examples:
    Touch hdfs:///some/path/
    Touch /some/local/machine/path/
  2. Depends on environment, e.g. ‘PROD’/‘TEST’/‘DEV’, might be useful to be used this way:
    # on DEV:
    # on PROD:

    and then in ‘evs’ file:

    Touch "$OUTPUT_DIR"
