General :: Writing Text To A File?
Mar 18, 2010I am using Grass GIS
I have written a script which outputs a list of numbers to a file
code snippet:
r.stats -1 fs=, input=Bones_AVE > /home/gary/AVE_monte_carlo/rstats_AVE$i.csv
so this makes acsv file with one column. I want to run it again but rather than outputing to a new csv i want to add it to this one as the next column. For this example there will be 100 rows per column.
the 1st one will make the file
[grassGIS code]> /home/gary/AVE_monte_carlo/rstats_AVE.csv
add ',' after each value
the next one
[grassGIS code] open file /home/gary/AVE_monte_carlo/rstats_AVE.csv

Programming :: Parse Multiple Variable From Text File With Bash?
Jul 13, 2010I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:
:::::::::::
var1=value1
var2=value2
[code].....
I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.

General :: Extracting Information From Multiple Text Documents?
Jul 7, 2010I am an astronomy student using Ubunut 10.04, and a frequent user of IRAF ( an *nix image processing application geared toward astronomy). IRAF produces, amongst other things, a text document with various values on it (example below).
Code: K IRAF = NOAO/IRAFV2.14.1 version %-23s
#K USER = name %-23s
#K HOST = Balthazar computer %-23s
#K DATE = 2010-04-29 yyyy-mm-dd %-23s
[Code]...
Now, the information I'm actually interested is the X and Y coordinates down towards the bottom (in this case, 973.505, 271.474).
I have about 800 of these output text files, and I was wondering if there's any sort of script or command that could go through them (presumably reading from a list of file names), and extract the coordinates. Ideally, the output would be a list of coordinates (i.e. X-coordinate, Y-coordinate).
Programming :: Parse Text For Host List?
Feb 22, 2011To run a parallel chemistry program, I need to build the host list. The cluster already has SGE(grid engine) installed and it generates a host list file with the following contents:
compute-1-1.local 2 all.q@compute-1-1.local UNDEFINED
compute-2-1.local 2 all.q@compute-1-1.local UNDEFINED
The important bits are hostname(ex compute-1-1) and number of cpus to use(ex 2). And for this program, it wants them in this form, a shell variable: HOSTLIST=hostname:cpus=X hostname:cpus=X .... I've tried this script, but it doesn't work
Code:

Ubuntu :: 10.4 Firefox Highlighing Bug - Writing Text
Jul 15, 2010I'm having problems with writing text. It usually happens in the google search bar next to the address bar in firefox. The text sometimes automatically highlights itself at what appears to be random intervals, so i usually end up with the last part of a word (which is usually over-writing the first half, which was highlighted). This is extremely annoying as i have no clue what i could have done to cause this.

General :: Detect If A Program Is Writing To A File?
Mar 3, 2009I have custom software that writes to a sensitive large file when the user does something. I would like to make backup copies of The file that gets written to, but if I make a gzip of the file at the same time someone is changing something, it will corrupt the backup because some of the data will be missing, as its backed up during being written to.
a) Is there a way to detect if a file is currently being accessed/written to?
That way if its currently being accessed, I can just make the script wait until its done and then finally back it up.
b) Instead of backing up the large file while it has potential to get written to, would it be better to make a copy of the file first, then gzip the copy? This idea comes from the fact that gzipping the original takes 5-10 seconds, whereas making a copy only takes 1-2 seconds. The less time, the less chance of corruption.
c) Is there anyway to freeze a program or a file to stop it from being written to for an amount of time?
With a, b, and c together. The best solution I have to my problem would be a script that first detects rather the file is being accessed. If not, it would then freeze the file/program and then make a quick copy of it. Once the copy is created, it will unfreeze the original file/program and then go about gzipping the copy.

Jul 31, 2010When I view a file in Linux with the 'less' command, I often only get a ":" prompt in the bottom left corner. There's no clue about how long the file will be, or at which location I am currently. When reading manpages with 'man', there's a file title and line number in that corner. And once I hit the end of the file, there's even a percentage shown. I've learned about 'less -m' but it's not that powerful. So what does 'man' differently from 'less'? They appear to be the same viewing programme, except for that file information difference.

General :: Removing Write Permission Does Not Prevent Root From Writing To File
Feb 3, 2010I just noticed on my Ubuntu machine (ext3 filesystem) that removing write permissions from a file does not keep root from writing to it. Is this a general rule of UNIX file permissions? Or specific to Ubuntu? Or a misconfiguration on my machine? Writing to the file fails (as expected) if I do this from my normal user account.Is this normal behavior?Is there a way to prevent root from accidentally writing to a file (Preferably using normal filesystem mechanisms, not AppArmor, etc.)
I understand that root has total control over the system and can, eg, change the permissions on any file.My question is whether currently set permissions are enforced on code running as root. The idea is the root user preventing her/himself from accidentally writing to a file. also understand that one should not be logged in as root for normal operations.
