Although "not my question", thanks, I learned a lot about array processing from your example. ----- Original Message ----- From: "warren" <warren at etr-usa.com> To: "centos" <centos at centos.org> Sent: Wednesday, October 25, 2017 11:47:12 AM Subject: Re: [CentOS] [OT] Bash help On Oct 25, 2017, at 10:02 AM, Mark Haney <mark.haney at neonova.net>

I have a brand new 2T external Samsung SSD disk. (two of them) for backup. I tried the first one and had an issue, I tried the second one and got the same issue. Am I doing something wrong ? I find it hard to believe the SSD (both) are bad. I plugged in the USB 3.1 adapter, I fdisk /dev/sdd, n, p, default, default, w. then mkfs.ext4 -j /dev/sdd1, then just mount and rsync.

There was a thread about C7 bash completion back in August last year, but it doesn't have answers for this problem. Example: "yum install /path/to/local/package" works fine with tab completion to fill in the path and package bits. However, "yum --debuglevel="1" install ..." just gets stuck and doesn't offer anything. The only option is to type everything

Once upon a time, Leroy Tennison <leroy at datavoiceint.com> said: > The executable could be placed on mounted read-only media That's not as secure as you think. Linux bind mounts can mount a file over another file (plus there's overlay filesystems), so it's possible to replace a binary even on a read-only device. -- Chris Adams <linux at cmadams.net>

Hi Leroy, How I can confirm that during rsync transfer corruption are not encountered? Thank you in advance.

I have had a single situation where corruption occurred during transfer (a few times, have no idea why),

Hi, I would like to know about which threads will be preempted by which on my OpenSolaris machine. Therefore, I ran a multithreaded program "myprogram" with 32 threads on my 24-core Solaris machine. I make sure that each thread of my program has same priority (priority zero), so that we can reduce priority inversions (saving preemptions -- system overhead). However, I ran the following

Without context it's impossible to make firm statements but, having gone through this a while back (and discovering that less than 1 percent of an examined list of connections couldn't support current ssl - mainly Apple hardware), who do you want to protect? Is it the minority who won't/can't upgrade or the majority who have? And, do you have to protect yourself from liability

I need to connect an older APS UPS unit to a machine running CentOS 7. Unfortunately the UPS only has a serial port whereas the computer does not. I am aware that there are USB-serial adapters but that the hardware or the drivers might fall short of expectations. Does anyone have positive experience with such an adapter? Or, conversely, would recommend avoid a particular adapter?

Hi everyone, I have updated my backup server to CentOS 8.2. It runs bacula performing backup on disks. I would like to replicate backups on another offsite machine. I read about the ability to configure a new storage daemon in the offsite location and create a Migration/Copy Jobs. If I'm not wrong, it replicates only volumes but not replicate the catalog. I will try this. Another way to

Is it possible with "chage" to configure a password caducity for, at most, 2 hours? I think "chage" only allows caducity for, at least, one day.

Hi everyone. I have a problem running a Windows appilcation with wine. The application is a Acucobol program. When I run "wine wrun32.exe myprogram" it works ok. When I run "wine wrun32.exe -C config.cfg myprogram" wine says myprogram doesn't exist. Any help? -- Marcelo Arroyo

Hello, we are currently managing access permissions through classical user-group-others permissions on a multi-petabyte directory tree with partially very deep and broad directories. Projects are represented by directory trees and mapped through GIDs. Lately we had lots of "singular" permission request (one single user needs access to a single dataset but should not be able to

I have made many different attempts to run a R program in Batch mode. I run a DOS command like: C:\Progra~1\R\rw1061\bin\rterm.exe -q --no-restore --no-save myprogram.R out.txt What happens: 1. DOS Shell starts up well 2. R starts 3. I get the messages: "ARGUMENT 'myprogram.R' __ignored__" "ARGUMENT 'out.txt' __ignored__" 4. R Shell is ready to
