is it possible to write ksh script in the spec file? the target is after I perform rpm -i my_rpm.rpm according to the spec file , ksh script will do some installation & configuration for example run other script and edit some files
View 5 RepliesI have inherited our Linux packaging and as the number of versions increase, the number of conflicts is starting to get a bit unmanageable. I believe the easiest way would have been to keep the package names the same and just change the release in the spec file but unfortunately I am past that as a lot of these packages are rolled out to our estate. (I am told there were reasons for not keeping the package name the same and incrementing the version/release)
Is it possible to wildcard conflicts so I don't need to keep adding as new versions are created. For example, instead of using all the conflicts below, have something along the lines of AAtest45* <= 1.4 & BBtest45* <= 1.4 Meaning that all I would need to do was change this to 1.5 at the next release (the packages below version matched the release in the spec file)

I want to change some thing inside the post install script of an existing rpm.there is any way to create a nearest spec file of this rpm, in order to change a bit the post install script inside this spec and then create again the rpm with the fixed spec file? no body wrote any program that can create spec file(99% identical from the orig spec file?)?

I'm trying to create a set of rpm files to install the requirements for a program.I found a great utility named cpanspec that will create a spec file for perl modules and have started building rpm files. I was able to create an rpm file for Business::CreditCard as a regular user. Now I'm trying to build another module that requires B::CC, and rpmbuild -ba fails saying that I am missing B::CC. I don't want to install it just to create another rpm file.Is there a way to make rpmbuild "think" that B::CC is installed in the build environment without installing it on the system?

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

is there a way to specify that I need a 32bit version of a certain library on the "Requires" line of a SPEC file?Since my software contain (a lot of) binaries from other sources (not always RPM compatible) I had to do "AutoReqProv: No" so I can do it manually.Is there a way to explicid say that I need the 32bit version of some library?

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.
Go to a specified directory and open a log file and parse out specific information and dump it into another text file.
View 4 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 4 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.

I recently upgraded my file/media server to Fedora 11. After doing so, I can no longer copy large files to the server. The files begin to transfer, but typically after about 1gb of the file has transferred, the transfer stalls and ultimately fails with the message:
"Error writing to file: Input/output error"
I've run out of ideas as to what could cause this problem. I have tried the following:
1. Different NFS versions: NFS3 and NFS4
2. Tried copying the files to different physical drives on the server.
3. Tried copying the files from different physical drives on the client.
4. Tried different rsize and wsize block sizes when mounting the NFS share
5. Tried copying the files via a different protocol. SSH in this case. The file transfers are always successful when I use SSH.
Regardless of what I do, the result is the same. The file transfers always fail after approximately 1gb.
Some other notes.
1. Both the client and the server are running Fedora 11 kernel 2.6.29.5-191.fc11.x86_64
I am out of ideas. Has anyone else experienced something similar?

I installed ubuntu 10.04 desktop edition on 3 pc (there is not a server-client architecture). I installed samba.(and smbfs)
put the strings:
[name]
comment = ...
path = /...
guest ok = yes
read only = no
create mask = 0777
directory mask =0777
Computers that access to that directory do (on boot, with root privileges)
mount -t smbfs -o username="user",password="pass" //192.168.0.12/name /mnt/cartelladimontaggio
But if two users access to the same file, both are authorized writing on it! So changes made by one are lost when the other save.
I have 3 c files(one of them forks out 5 instances) all writing to one log file. Now to avoid the confusion of opening and closing in each application or instance and running into a situation of not having closed a file I decided to open and close the log file inside the log function for each write.
So what I do currently is fopen, flock, fwrite, unlock, fclose for each write. All the log messages from all the files get written fine and there are no errors but I see a performance hit. The applications talk to each other using SHM(shared memory). So when I try to set a timer and check number of messages lets say I get X messages. Each time I remove or add a log call the number of messages changes. When it is a 1 sec or 5 sec timer it doesnt make a very big diff..few hundreds but when I check it over a longer period..every log call added decreases 1000 messages in count. So I want to know what is an efficient way of implementing the custom log across the application.

it is about the program sha1sum to create SHA1-hashes. As you probably know, SHA1-Hashes do have the length 20 byte. So when I just type:
Code:
sha1sum myfile
it produces an output of
Code:
(some20byte) myfile
just as it should. Now I want to store the 20byte hash in another file, I use this command:
Code:
sha1sum myfile | awk "{print $1}" >> myhash
Unfortunately I'm not familiar with awk, but this should cut off the end of the sha1sum output, which is the name of the file again. The problem here is: The newly created file myhash has the size 41 bytes, and printing it out I can see that it is not the original hash (I wrote a little program to print it bytewise).
My program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.
