I'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
Below is an example output of what I see when I run the 'ls' command on some directories in linux (this is from a tomcat/common/lib directory). However I'm not clear on why some of the filenames are appearing inside [square brackets]

how to include my command results in a script? Basically what the script does is it checks the status of a service within the linux server, then sends an email when done. I want to include the results of my status check to my mail when sent.
i.e.
service dhcp3-server status Status of DHCP server: dhcpd3 is running. <---this I want to include in the mail that is sent out via script.
I wanted to supply mplayer with the output of find command as arguments. The error returned showed spliced names of files whenever spaces occurred. I have subdirectories in my /home/my_user_name/Music/ directory, and in them multiple *.oga music files. The actual command that I issued was
Code:
mplayer $(find /home/my_user_name/Music/ -name "*.oga")
mplayer started but then was looking for broken file names. I am thinking quoting has to do with it to preserve the filename as one string but different attempts were met with inroads:
Code:
mplayer `find /home/my_user_name/Music/ -name "*.oga"`
gave me the same result and
Code:
mplayer `"find /home/my_user_name/Music/ -name *.oga"`
complained about wrong mplayer syntax.
I scheduled a job, 'ls -a', with the at command, 3 minutes in the future. It looks like the job ran, but I cannot see the results of 'ls -a'. I accessed my mail with the 'mail' command and saw that the output of my scheduled job was message 1. I typed in '1' after the & prompt, and saw that the subject of the message was the output of my job, scheduled at the time specified with the 'at' command. I cannot see the output of the 'ls -a' command that I scheduled though. How do I see the contents of the message, and the actual output of the job.

It should read
Read: Address 0x00000037, Data: 0x0000000b
but sometimes it comes out to this
Read: Address 0x00000000, Data: 0x00000000
therefore ill have to run the command again IF I Dont get the right results...
i wonder if it is usual that the results of running commands via the command line is different from running them in a script file. my problem is that, i've to run 'modprobe -r e100' and 'modprobe e100' before suspend my machine via pmi in order to resume it properly. i wrote a script containg EXACTLY the same commands as i typed in the terminal/console but the result was not the same. the machine cannot be resumed as expected if i run the script file.

I use ssh for a headless unit and I can reboot fine, but I told it to shutdown and disconnected me and stopped logging (as far as I can tell) and then nothing. The lights stayed on and I had to press the power button. Is there a way to keep the logger running or to look someplace other then messages. I'm not great with logs.

I am having trouble with encryption/ decryption program.

The thing I love most about 10.04 has been the boot times. Now, sadly that is gone for me... Suddenly it takes longer to boot. With almost no new apps installed and I have a separate disk for music/videos and such. Also, removed most of startup-applications!

I am trying to determine CPU usage on a radio controller running Linux. We have a script that another member of my work wrote using vmstat which I could not get any consistant results from. So, in an effort to understand what was going on I wrote a script using ps. Sadley after running several tests using both scripts, they do no match up at all, vmstat always gives me a much higher value. However, if I simply run the commands at any given time they do match up, therefore I believe that there is an error in one of the scripts. I am very new to linux and so Here is the vmstat script:

The system of my VPS is centos 5. I want to know if it is 32bit or 64bit. > uname -a Thu May 13 13:49:53 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
looks like 64 bit.
But
> getconf WORD_BIT
32
Looks like 32 bit.
Which is correct?
I believe the linux of my VPS is 32 bit. Because I downloaded a 64bit mongodb, found it can't start. And when I downloaded a 32bit instead, it works well.

View 3 Replies View RelatedI've setup a git-svn repo with cron to fetch from the svn repo daily. I have a script to do the fetching, and this is what is invoked by cron. Everything is fine with the repo, and the script works fine when executed manually. However, when it runs under cron, empty files get dropped into the .git directory. The files have names that look like they are some base64 output, e.g. juTrvjP6m8 and kcKf3hu3b4. Two of these files show up for every cron run. I thought these might be commit hashes, but they're not, git-show says it's an unknown revision. I set-up the repo as follows:

The last line pushes the repo to a separate (bare) public repo from which others can clone. I'm piping the output from the cron job to a file, which looks like this:

The line "fatal: unable to run 'git-svn'" is alarming, but the fetch seems to go ahead anyway. Where are these empty garbage files coming from, and how to stop them? Am I in for bigger problems in the future?
