John Zhuge commented on HADOOP-12832:
-------------------------------------
A new FsShell {{touch}} command with these features to replace {{touchz}}?
{code}
hdfs dfs -touch [-m] [-a] [-t <timestamp>] <file>
Changes both modification and access time of a file if it exists; otherwise,
creates a new 0-length file.
-m change only the modification time
-a change only the access time
-t use [CC]YY]MMDDhhmm[.ss] instead of current time
When both -m and -a flag are specified or neither is specified, change both
modification and access time.
{code}
This looks more familiar to Unix/Linux users than a new FsShell {{setTimes}} or
{{utime/utimes}} command. {{utime/utimes}} is a Linux syscall to change file
last access and modification times.
> Implement unix-like 'FsShell -touch'

> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs
> Affects Versions: 2.6.4
> Reporter: Gera Shegalov
> Assignee: John Zhuge
>
> We needed to touch a bunch of files as in
> https://en.wikipedia.org/wiki/Touch_(Unix) .
> Because FsShell does not expose FileSystem#setTimes , we had to do it
> programmatically in Scalding REPL. Seems like it should not be this
> complicated.
