0:0:35
0:0:36
0:0:28
0:0:37
0:0:43
0:1:2
This is actually in a time format(hh:mm:ss) and how do i add all the values and get the sum in seconds . the output should be in seconds like total number of seconds : 241 secs
Currently whenever i run date command output is shown like
Mon Apr 12 05:17:21 IST 2010
When its 17:17 Here.
How would i change it so that it should show.

View 4 Replies View RelatedI have a script that is in Unix. I wanted to know is there any difference between output of ls command in unix and linux
In Unix
Code:
ls -ltr | awk '{print $9}'
In linux output is something similar to
Code:
drwxrwxrwx 2 vinay vinay 4096 2010-02-04 20:31 test
According to above output nothing will be displayed for
Code:
ls -ltr | awk '{print $9}'
ls -ltr | awk '{print $8}' will give test as ouptut in Linux.
I wanted to check the output format for ls -ltr, Anyone using Unix systems may paste a sample output of the command ls -ltr..
I use to know this command but lost it and did not note the entire command on my Linux cheat sheet. Someone once showed me a simple very easy command I could use to simple format a USB flash drive as FAT32 and in the same command also name the label of the drive.I have the device /dev/sdc1 and I am formatting this as FAT32 so it's compatible across multiple systems but also want the drive to have the name 'my_usb'.

View 1 Replies View RelatedI'm timing how long it takes to run a command foo. I'm looking to append the results from the time command to a file, and discard the results from the foo command. I tried the following, but it didn't do what I want:
$ time ./foo > /dev/null >> output_from_time_command.txt
I am trying to use the time command to measure the execution time of a small program. The problem is that the command has three outputs. They look like this:
Code:
$ time ./a.out
real0m51.935s
user0m51.060s
sys0m0.040s
Should the execution time be the sum of the user and the sys time? sys time is really small.
I have made a shell script as below to find that how much time is taking between one command to another.
View 3 Replies View RelatedI am running a script with nohup and this generates a lot of logs.
In order to view the log I use tail -f nohup.out
The problem is that the info supplied by this command is not always the latest//sometimes I need to use the command again order to view the latest info added to the nohup.out file.
I would appreciate help with how to extract the date and time from at command jobs. From what I can tell, the date and time is embedded in the file name (/var/spool/atjobs).I'd be using this information in a (bash) shell script.
View 14 Replies View RelatedI use the time command to measure the wall-clock time of a GPU implementation of an algorithm. When I time the CPU execution of the algorithm time returns a negligible sys time. However, when I time the GPU execution time returns a sys time that is around 20-30% of the total time. If that time was comparable with the negligible sys time of the CPU I would achieve a speedup of a few times higher.
I suspect that the increased sys time is because of the GPU usage, which, I assume, takes some time for the OS because of the drivers etc. I am not sure though, and it is important to figure this out because it will improve my results a lot if I can ignore the sys time and use just the user time for speedup calculations. Also, is there a way to see, in detail, what is the sys running and takes so much time. I am thinking that I might be able to see if it is the driver indeed that causes this delay.
I was reading that if I want to do a one time scheduled command, I should use at, which I've never done, as opposed to cron, which i'm kinda familiar with. But what I want to do is reboot my server at 3am tomorrow and force it to check the file systems with a shutdown -rF. For this do I even need to use "at" or could I just say shutdown -rF 3:00.Will that also know that I mean 3am tomorrow and not say in 3 minutes from now or 3pm?

I set my location, but Debian displays DATE in some messed format. I would expect such neat OS to recognize all those local settings based on my location, but that's not the case. It seems that Debian follows locale settings by set language (which is en_us in my case, as I guess in majority uses) or this format is default in any case
I would like to set date/time to DD.MM.YY. hh:mm:ss, and programs that display date data to follow this setting. Simply put, in Windows there is Control Panel and you set location, then OS uses some regional settings, like currency, separators, date/time format.

View 4 Replies View RelatedFor some reason, thunderbird uses some random order for the date elements, e.g. MM/DD/YY. I need to change it to YYYY/MM/DD but haven't found where! There is no option in TB to configure this so I guess it just picks some default from regional settings? Where do I need to go to set the date format to its logical form?
View 3 Replies View RelatedIn KWrite, you can make a datestamp and timestamp by pressing F7 for a command line and typing "date" therein. I just wondered: is it possible to change the stamp's date/time format, which is mm/dd/yy 24-hour time format? That's fine, but I wish the stamp could include the day of the week. (I use KWrite to keep a text-only personal journal. Any suggestions that I use a different program are welcome but are beside the point.)
I looked through the editor settings options, but found nothing relevant. The settings don't mention the F7 command line and the datestamp/timestamp at all; the only reason I know is because I once asked if there was a way to make one, as in Windows Notepad.
In windows, you could do a dir | more to scroll one page a time.How does one do this in Linux?
