Or zip VS gzip VS bzip2 VS xz
In a previous article about the tar program I mentioned gzip and bzip2 compression methods as options to create a tarball (and I forgot xz).
To make amends today I will introduce the main methods to compress the file and I’ll do some tests to see how they behave.
Hi all, I have the requirement to generate the file containing following command
eval /path/ dsjob -logdetail projectname JOBNAME /path/
1. The file contains the above command say about 150 times i,e only the JOBNAME changes in every command
2. The commands must be written in such a way that it has to run in parallel.
3. I need to call this file from the script.
I have a small script that loops through all files of a folder and executes a (usually long lasting) command. Basically it's
for file in ./folder/*;
do
./bin/myProgram $file > ./done/$file
done
(Please Ignore syntax errors, it's just pseudo code).
I now wanted to run this script twice at the same time. Obviously, the execution is unnecessary if ./done/$file exists.
In the "Why Xar" page of the Xar google code page it says:
"Additionally, this means xar can use different compression methods for
each file in the archive.
I has had tried to execute this command, and...
phoenix:/export/backups/controle/200912 # bzip2 bkpbd_eti-200912061300.tar
bzip2: I/O or other error, bailing out. Possible reason follows.
bzip2: No space left on device
Input file = bkpbd_eti-200912061300.tar, output file = bkpbd_eti-200912061300.tar.bz2

Apologies if this is off topic - it concerns the relative efficiencies of running I/O-heavy Perl/Java scripts in parallel on a Ubuntu system.
I have written two simple versions of a file copy script (Perl and Java) - see below.
Is it possible to redirect get command inside ftp client?I was only able to do "get filename /dev/null" to redirect it to /dev/null.. However..
Any hard numbers, or rules-of-thumgs, for what workload (e.g. in terms of simultaneously active users running average HPC center jobs) on a computer cluster, that would make a parallel network shared file system such as Lustre, GPFS, Ibrix or Panasas, a requirement?
...that is, when is SAN storage not enough anymore, and you need some kind of parallel NAS?
