Have this script which is reading in a series of files, one at a time with while-do-done loop, each file goes through various greps/awk's where this info is then saved to various files for later use. i.e....
Script is being run on Linux Red Hat,
In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)
i.e. (example from above)
Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?
I have a cluster of 50 machines and some machines already have ssh automatic login setup but I want to be able to check this with a script.

View 1 Replies View RelatedI have a network of 20 machines, all running Ubuntu 10.04.
Each machine has about 200[GB] of data that I'd like to share with all other 19 machines for READ ONLY PURPOSES. The reading should be done at the FASTEST POSSIBLE WAY.
A friend told me to look into setting up HTTP / FTP. Is it indeed the optimal way to share data between the machines (better than NFS)? if so, how do I go about it?
UPDATE: Just to clarify, all I want is to be able (from within machine X) to access one of machine Ys files and LOAD IT INTO MEMORY. all of the files are of uniform size (500 [KB]). Which method is fastest (SAMBA / NFS / HTTP / FTP)?
Im new to the forum and fairly new to Linux as well. my apologies if this is posted in the wrong section. My problem is How can you search for a file in multiple machines (like a server farm) ? For example i log onto machine num1 and want to search for a file named "xxx.yyy" which may be in one of 4 machnies. What i do right now is manually log into each machine and run the find command. However i have heard that it is possible to do it via a couple of simple commands. I have looked into pssh and cssh as well as ssh tunneling (along with public key authentication to stop the machines requesting a password every time i log in) and unfortunately i was unable to find an answer.

I need to transpose a file with over a 1000 rows of 5 columns of numbers into a file with a single column of numbers. The numbers are separated by a single space and range from one digit to 5 digits each. I tried using awk, but can only get it to grab one column of numbers.
Input:

So pls tell me how to write the make file for it?

I want to do something like svn add dir1 dir2; svn ci dir1 dir2 but have it be only 1 revision. Is there a way to do this?

View 1 Replies View RelatedI've written a script (that doesn't work) that looks something like this:
#!/bin/sh
screen -dmS "somename" somecommand
for i in {0..5}; do
screen -dmS "name$i" anothercommand $i
done
For some reason, if I copy and paste this into a terminal, it creates 7 detached screen sessions as I expect. If I run it from within a script, however, I get only the first session, "somename," when I run screen -ls.
Edit: If the same can be accomplished another way (e.g. with multiple screen windows instead of sessions), I would be open those solutions as well.
How can I configure a single computer to work for multiple simultaneous users? I would like to have multiple keyboards and monitors on a single PC ... Is it possible? This set up I'm planning for CyberCafe, For cyberCafe business ROI is very slow... so was planning to have something like this....

-Multiple monitors, keyboards, Headphones etc....
If this works out then I would save a lot on my investments (OS cost, Hardware devices, electricity etc)
I am using Xfce as the desktop enviroment and Mozilla Firefox as the webrowser. Within the webrowser window, I do File>Save Page As. I save it, and the result is almost always foo.html and directory foo_files. But I think under KDE I could choose the format, one of them being something like "Single page" (only one file; the colecction of .png, etc is embedded into that file). And this is the format I want Xfce (or Firefox) to use when downloading to hdd.

I'm trying to create a user john with default password 'abcdef'. I used the following command.
useradd john -p abcdef
I can't login with the password. in /etc/shadow file I can see the password in clear text format. how I can create a user along with password.
I wish to allow a user to use sudo to run a single command (service app status) to determine if my application app is running, in my sudoers file i have: user ALL= /sbin/service app status I understand that there is a parameter called timestamp_timeout that will set the timeout for the 'user', but requires at least 1 entry of the root password.
I wish to allow the user to do "sudo service app status" and not have to enter the root password ever(maybe once is ok), but still make the user enter the root password for all other root activities. Is there a way to prevent the password entry for this command only and no others?
I just installed ubuntu 10.04 x64. I have installed it and set it up the way I like on my server, however I now have 3 terminals and a laptop to set it up on the exact same way. As a result Id like some advice on what can and cant be done and how. Preferably I am looking to use programs with GUIs. Thing the style of ubuntu one, software manager etc, not really too into the command line, or conf editing unless there is no other option.
1. I installed all the software from software centre I like. Now I need the same software on the other computers. I know mint has mintbackup where it just exports and imports a list if installed software. I am looking for an ubuntu equivalent.
2. Firefox and Thunderbird add-ons. I install like 20 firefox and thunderbird add ons. sometimes I can't even keep track of them. There must be a way to sync them so that each computer I install ubuntu on I can simply import the list of mozilla add ons and have it auto download them.
3. Mail Contacts and Calender Syncing. I need to sync between my 3 ubuntu machines and my windows mobile 6.5 device for calender, email/phone/name contact lists. Email is taken care of by imap, but lightnings calender isnt and neither are the contacts. If I input a contact on my phone I want it to sync to the other computers I use.
4. Ubuntu one. I have /storage/workfolder in my root directory on my personal server. I want to be able to work on documents at work on my laptop and sync them so that when I get home, they are synced on the server without causing overwrite changes etc.
5. Desktop settings, icon themes, preferences from ubuntu tweak etc. I know this one is a bit more of a long shot, but it takes 20 minutes each computer, to set up the little maximize minimize buttons on the other side, set up cairo dock the way I like, install the icon theme and backgrounds I like. isnt there a way to back this up so it doesnt have to be done each time or so I can make my other computers the same?
