I 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

I 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.

View 3 Replies View RelatedI 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.

View 10 Replies View RelatedI am running Intrepid Ibex 64-bit, and I have recently ripped a cd with EAC on one of my windows boxes, and it produced a cue sheet and one single wave file for the entire cd. My question is this, is it possible to take the wave file, burn an ISO image that acts exactly like the original cd? In other words, take the single wave file, using the cue sheet splitting it back into it's individual tracks, and then reading the subsequent ISO image from a program like Sound Juicer, so it can write all the metadata and convert it with my own preferences. I know this is a very strange predicament, but it's one that would save me a world of hassle.

Many years ago, I converted a portion of my files to an arbitrary format with a specific extension. i no longer desire to have them in this format and i would like begin the process of replacing them because conversion is not an appropriate solution. unfortunately, they are mixed in separate folders of the same root folder with files in my current format of a different extension. I feel it would make this process easier if I were to move every folder that contained a file with the undesired format to a separate root folder. The files are stored on a Linux server and shared via samba. How can I do this with a couple of commands or a script? I am open to other suggestions as well. I want to avoid time spent editing text files. Ultimately, I'd like a command that produced a list of full paths for folders, sorted by the number of levels would be a nice touch. A list of all of the files is clearly not what I'm looking for.

I'm new to the shell scripting. can any one help in creating shell script for matching the content of the specific variable with file. it should remove that line from the file if line is containing same value as variable and keep the other content as it is.i used grep -v for accomplishing the same. But grep will remove the pattern which is similar.For eg. Assume file "test" contain datas :aaffif i used grep -v command for the pattern "a" to this file this will remove content "aa" from the file. I want the pattern only "a" should remove from the file, if it is existing. otherwise it should throw alert content not exists.
