I need to redirect the output of a command that I am running to a log file with timestamp (hence a function instead of the log file itself) but the error and the output, both should not be showing in the console. The following -

command | my_func 2> /dev/null

is not working.

Something like

command 2> logfile

works, but I can't record the timestamp in the second case. What should I do?

I'm using mount.cifs to map a windows folder, then I copy hundred of files at once from windows to Ubuntu. After that all files are syncronized and the modification times as well. On Windows using explorer I see that not all but a very few files have a difference of 1 hour from the copied files on Ubuntu. Why on windows almost all files match the modification time but some do not? I had to edit this post to explain that I think it is not related to the UTC and it is not a duplicated question. I'm just comparing a list of over 2000 files with the filenames and timestamps, one file generated on Windows and one file generated on Linux. I compare these 2 files and then I copy only the modified files. Even these files were all updated I keep copying 14 files every time.

While reading about Linux I got the following:

touch provides several options, but here is one of interest:

The -t option allows you to set the date and time stamp of the file. To set the time stamp to a specific time:

$ touch -t 03201600 myfile

This sets the file, myfile's, time stamp to 4 p.m., March 20th (03 20 1600).

Here, I am not getting the logic behind 03201600 --> 4pm, March 20th.
