John Zhuge commented on HADOOP-12832:
-
A new FsShell {{touch}} command with these features to replace {{touchz}}?
{code}
hdfs dfs -touch [-m] [-a] [-t ]
Changes both modification and access time of a file if it exists; otherwise,
creates a new 0-length file.
-mchange only the modification time
-achange only the access time
-tuse [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.

I would also argue that *touchz* should be deprecated and replaced by a more conventional *touch*. > Implement unix-like 'FsShell -touch' > - > > Key: HADOOP-12832 > URL: https://issues.apache.org/jira/browse/HADOOP-12832 > Project: Hadoop Common > Issue Type: New Feature > Components: fs >Affects Versions: 2.6.4 >Reporter: Gera Shegalov > > 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.
