I have the problem,that the following code doesn't work.
start "" "datetime.exe" +%s -d "!timestamp!">tmp_datetime.txt
in cmd it works well, the variable timestamp is in the right Format.
for cmd I type the following
datetime.exe +%s -d "YYYY-MM-ddTHH:mm:ss"
and back comes the date as unix timestamp.
After running my Batch file with the start command, the tmp_datetime.txt is empty
Please try to use "call" instead of "start". Start will open a new window. I think there goes the problem with.
So try this one:
call datetime.exe +%s -d "!timestamp!">tmp_datetime.txt

I'm currently trying to use exiftool on Windows command prompt to read meta data from multiple files, then output to a single text file.
The exact command I last tried looked like this:
exiftool.exe -FileName -GPSPosition -CreateDate -d "%m:%d:%Y %H:%M:%S" -c "%d° %d' %.2f"\" -charset UTF-8 -ext jpg -w _Coordinate_Date.txt S:\Nick\Test\
When I run this, I get 7 individual text files with the content for one corresponding file in each of them. However, I simply want to output all of it to one single text file. Any help is greatly appreciated
The -w (textout) option can only be used to write multiple files. It is not meant to be used to output to a single file. As per the docs on -w:
It is not possible to specify a simple filename as an argument -- creating a single output file from multiple source files is typically done by shell redirection
Which is what you're doing with the >> ./output.txt part of your command. The -w _Coordinate_Date.txt isn't doing anything and I would think throw an Invalid TAG name: "w _Coordinate_Date.txt" error if quoted together like that as it gets treated as a single arugment. The -w option requires two arguments, the -w and either an extension or a format string.
I actually figured it out, if you wrap the entire -w _Coordinate_Date.txt command in quotations and append it to a file, you can throw all of the output into one text file.
i.e. "-w _Coordinate_Date.txt >> ./output.txt"
How to convert any date to YYYYMMDDHHMMSS using unix shell script?
It is not specific date it may any date. how to convert it?
example date format is: 20110101050603
Thanks

DATE = "15 Jun 2015 10:10:10"; date -d"$DATE" +%Y%m%d%H%M%S
Output :-
20150615101010
More on Dates
Note this only works on GNU date.
I have read that:
Solaris version of date, which is unable to support -d can be resolve with replacing sunfreeware.com version of date.
Update:-
Use ls command to find all files and use grep command for all files.
ls | grep "[0-9]{14}"
grep command also accepts regular expression.
But it won't validate your file accurate. For example, if a file name is 20151835101010, then it will validate this file. But actually month and date both are wrong.
So my suggestion is to write a shell script to identify valid file name and find oldest of them by processing one by one.
I am trying to log a complete session in psql into a .txt file. The command given to me was initially this:
psql db_name| tee file_name.txt
However, my SSH client does nothing until I quit it. That means, it does not recognize any command. More like a document, no action happens no matter what I write. So far, only '\q' is recognised which lets me get out of it. Any ideas what is happening? How am I to write the query if shell will not read anything. Also, I tried the following (this is before connecting to database) :
script filename.txt
It does show the message : script started, file is filename.txt, but I dont know where this file is stored and how to retrieve it.
Any help with the above will be welcome and really appreciated! Thanks a lot :)
There is option to psql for log query and results:
-L filename
--log-file filename
Write all query output into file filename, in addition to the normal output destination.
Try this:
psql db_name -L file_name.txt
I need to create output files that include the input I'm providing. For example, a run of the program might look like:
Input command: do_things
Things have been done.
Input command: stop_doing_things
Things are no longer being done.
Where "do_things" and "stop_doing_things" are input from the user.
How can I output all of the above to a file using command prompt functions?
It's not clear what environment using "script " command linux will open a new shell and save everything done it to
This works for you, if you run it at last...
CMD > D:\mycmdout.txt
In that case, maybe you can capture your input as a variable. Echo the variable into the >> mycmdout.txt, then procede with the actual commands, again piped into >> mycmdout.txt as Sunny suggested.
SET /P variable=EnterInputHere
echo %variable% >> mycmdout.txt
EDIT: Be sure to use double >> as to append result to file.
I am using oozie to run my map-reduce job. I want to create the output file according to the date. But it takes date as a string and ends up printing instead of taking date as the value :
/user/skataria/geooutput/$(date +"%m%d%Y%H%M%S")
Here is the oozie properties file:
nameNode=hdfs://localhost:8020
jobTracker=localhost:8021
date=(date +"%m%d%Y%H%M%S")
oozie.wf.application.path=${nameNode}/services/advert/sid
inputDir=${nameNode}/user/${user.name}/geoinput/testgeo
outputDir=${nameNode}/user/${user.name}/geooutput/${date}
Somehow i cant have oozie as tag because my reputation is under 1500
It looks like you're trying to use a linux shell command (date +"%m%d%Y%H%M%S") in a java properties file - this isn't going to resolve.
One work around, assuming this is part of a manually submitted Workflow job (as opposed to a Coordinator job) is to provide the date property from the command line using the -D key=value option, and linux shell back quotes to resolve the output of a command inline
oozie job -run -config job.properties -D date=`date +"%m%d%Y%H%M%S"`
You'll need to make sure your version of Oozie support the -D key=value option
Yes I agree the shell option works. But that does not solve my usecase. I want to run my map-reduce job daily and schedule this thru Hue. The output directory needs to be parameterized as an job property to Oozie.
By the way I find that Oozie has Expression language Functions,
Unfortunately the function timestamp() returns the UTC current date and time in W3C format down to the second (YYYY-MM-DDThh:mm:ss.sZ). i.e.: 1997-07-16T19:20:30.45Z and completely unusable for creating a sub-directory name in HDFS
So for now,
I have a workaround. I am using the Workflow EL Function wf:id()
In workflow.xml
<property>
<name>mapreduce.output.fileoutputformat.outputdir</name>
<value>/user/sasubramanian/impressions/output/outpdir/${yyyy_mm_dd}/${wf:id()}</value>
</property>
This creates a output directory with subdirectory as,
/user/foouser/subdir1/output/outpdir/0000006-130321100837625-oozie-oozi-W
NOTE: You must specify this in the workflow.xml. This will not work if you specified it in the job.properties
