This question may be silly and super easy for linux connaisseurs, but I was just wondering, for instance, I want to use the >find command to search for a file and send the results to a text file
View 5 RepliesI'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
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.
I wonder if the unix commands (cp, mv, grep, args etc) are the same for Mac and Ubuntu. Do they have the same parameter lists and so on or do they try to stay the same but are slightly different?

View 1 Replies View RelatedI've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP).
The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace). I feel like a really need like a "rescue" cheatsheet for things like: how to save the X no matter what without pressing reset how to reset the system to "normal state" how to connect to the internet through the command line how to monitor what the X is doing (using ubuntu linux 10.04 btw)

I am trying to store the results of my code to a separate text file.But the problem is, as my results comes from a loop, my text file shows only the last result, not all of them.Like if the loop runs 5 time the text file shows the result for the 5th step.But i need to store all of them (1 to 5).Can I use awk to print the output field and store to another file and creat a new line so that the next output field goes to a new line?(just an idea, dont know).
#!/bin/basth
for (( i=1; i<=5; i++))
do
./file.exe > output.txt

View 2 Replies View RelatedI'm pretty sure this is super simple, but I've searched and searched and for the life of me I can't find any info on how to limit the columns that display in the interactive top program with arguments passed from the command line. I recall seeing something formatted like this ...
~/top -f (kdx)
Which would only show the %CPU, UID, program name fields/columns. I'd like to display the results in a really narrow terminal window on the right side of my desktop.
I hope to add a wrapper script for the command with different parameters. For example, for any Unix command or script, like below:
command.sh -s p1 -o p2 -q p3
or
command.sh
Probably we could do as this way
cat wrapper
$1 $2 $3 $4 $5 $6 $7 | tee test.log
(assume it has 0 to 6 parameters)
and use it like
wrapper command.sh -s p1 -o p2 -q p3
wrapper command.sh
It is a little ugly to list all fixed parameter as above, do we have better code to handle various parameters?

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.

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 have a few questions regarding HTML, UNIX and Javascript. I've been tasked with creating a fairly simple webpage that takes a few inputs. Each input must correspond to an argument in a UNIX command running on a server.On a UNIX server we have a script (.ksh) that takes 3 arguments. The result of the script is a data file which is FTP'ed to an external server. Let's forget about the FTP portion for now. I would like to know where I should begin.What I know so far:
1) I will need HTML to create the webpage. Skill level is high
2) I will need Javascript to make my webpage more interactive. Skill level is high.
3) I will need to understand the UNIX environment. Skill level is high.
When looking for a certain word or phrase in the man page of linux command, one can type '/' followed by the word/phrase to search for it. What I'd like to be able to do is to search for the next occurrence of the word/phrase without having to type it out again. Kinda like when you use 'ctrl+f' in a browser to search for a word, and then press 'enter' to find the next occurrence of that word.If this is possible to do, how do I do it?

instead of [URL] I would want to input username directly into the server, just like it is done using putty on windows. he wants to be prompted for a username, rather than having to provide one when connecting - but I don't really see the utility in such a thing. - birryree Sep 8 at 17:41
Unix command that allows to know which process is running on processor core?

So How can I make this command work?
I have a dual-boot windows and Suse linux 11.1 setup. I can save and restore a linux image. Trying to save an image of Windows results in Partimage freezing at the "NTFS Information" window before the "save partition to image file." I have two SystemRescue CDs of versions 1.2.2 and 1.2.3 I have two computers one with Windows 2000 and one with Windows XP I have defragmented the partitions several times over. Users are told that use with "NTFS is experimantal". Several up-beat webpage tutorials also mention this but go on to say how marvellous it works for them. Naturally, such sites do not mention problems. This is the province of the forums. I have found nothing that relates to my problem though. Hence my post appealing for any guidance on offer.
