View 1 Replies View RelatedWhen I try to compile some Java code on Ubuntu 10.10 (kernel 2.6+) using make and a Makefile.
I get an error indicating that the make utility cannot execute the java compile command (javac).
The error reads: /bin/bash: line 6: .: /usr/local/jdk1.5.0_18/bin/javac: cannot execute binary file
I am executing make as root. I have enabled permissions on all directories in the path /usr/local/jdk1.5.0_18/bin/javac and on javac itself.
I get this error whether using a jdk installed via ubuntu apt-get, or whether I install the jdk myself. And I get it using either Java 1.5 or 1.6
My machine has an 80386 processor. I notice the make utility is built for i686-pc-linux-gnu
However, I can manually compile using javac.
I can compile calling javac from within a bash script.
I can compile using the java compiler gcj from the command line: gcj --main=HelloWorld HelloWorld.java -o HelloWorld.exe
But I cannot compile java code from the makefile. Any reasons why I might be getting this error?

I have Ubuntu installed in a virtual machine (VirtualBox) with a separate virtual drive that receives rsync backups of some of my online servers.Itns a series of 4 rsync commands. The first two ran fine, not sure about the third and the fourth wrote nothing. The error in rsync said the file system was read only. I confirmed the whole drive was read only, but it did not start that way.I rebooted and the fourth rsync ran fine. I think this is a linux issue and not a VM issue, but it is clearly mounting in r-w and for some reason changed on it own to read only.Does anyone have any idea why this might occur?It is mounted through fstab with the line:UUID=84d4bc5c-7a68-4096-9725-214f2e8b713e /BackupDrive ext3 defaults 0 2

Initially I thought - use a for loop with ls in it:
Code:
However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).
The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.
I'm confused about "hard link" feature. I've been learning from my UNIX Academy DVDs training that hard links to a file can be many and each of them is an effective filename for the associated data. So let assume that we have some very sensitive data in a file and we want it to be deleted and file has 20 links. I "delete" a file, but in fact I deleted only one "name" of it. My understanding from the training that data is still there until we delete the last associated hard link. But how can I find the names of all of them? If we have the names, they can be removed one by one. Or may be there's command that can trace all the "names" and remove them at once?

I'm trying to write a shell script which finds bits of data from a text file. at the moment i'm using grep and basically i need a function which will look through the text file and take the data out of it. the file has days, months, years etc and i want it so i can type feb 06 and it finds all of the data for feb 06.
the problem i have is i can type feb and all the information comes back for feb, but i can't get it more precise e.g. feb 2009 and it finds just feb 2009, it seems to ignore that latter half. I've tried experimenting with egrep and having two inputs but i can't seem to fuse them together, it only takes the first input.
I would like to write a script that pulls the last line of data out of a txt file and then saves it to another txt file. The txt file that I am looking at resides here. [URL]
I know I can grab that file using wget. I've done a little scripting but nothing major.
basically the situation I'm in is someone mistakenly expanded an NAS without unmounting the drive on the server. This corrupted the superblock and its apparent that all the backups are no good. The drive in question was expanded from about 800gigs to 1.8TBs, its done via an NAS.
At this point I'm most concerned about getting the files off the drive, I can deal with resetting the file system but I really need those files. This happened within a week of me joining this group so I'm kind of doing damage control here, backups were not taken of this particular drive.

View 1 Replies View RelatedI manually rotated my catalina.out file, and now the file jumps to 30+Mb and when I try to view it, less tells me it might be a binary file. It sure appears to have binary data in it, about 30meg of it.
I did the rotate via a copy:
copy catalina.out to another file
cat /dev/null > catalina.out
I have tried using echo:
echo "" > catalina.out
...also with the same result.
This application isn't something I can just bounce when necessary. It kind of appears that the original file is still there - sort of. But is it not readable text anymore.

We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
