[opensuse] Verifying copied files - Global Settings and singular command switch
In DOS there was the ability to verify a singular files integrity by using chkdsk c:/file.dos......The result indicated if the file integrity was so. There was also the ability to set in the Autoexec.bat set verify=ON - which made sure that EVERY file that you copied you did not need to use the verify option C:\file.dos C:\temp\file.dos /v My questions are 1. Is there a global set verify=on in Linux? 2. Is there the ability to verify a single files integrity as above with a similar command such as chkdsk 3. How do I copy a file at the command line and include a verify option. The reason I ask is that I recently lost my home directory and I had KDAR backing up the /home directory every week to an NFS drive. When I came to restore the archive the files header was reported to be corrupted. Also as a backup I copied with Konqueror the /home directory to an NFS drive and some of the files are aslo now not readable due corruption. I have made an Enhancement report to both Konqueror and KDAR that they include a verify option like most backup programs. Over many years I have seen backups unable to be restored because verify was not turned on. Now its happened to me. I understand the file system in Linux is far superior in its disk I/O but I dont want to waste time backing up if I cannot ensure the files are intact. The current backup GUI's do not include a verify option and the only one that does 'cpio do not hav a GUI and due to the complexity of options available it is rather unfriendly. I have made a wish list item in opensuse to for someone to write a GUI for cpio which will also address a request to have the ability to backup to tape. regards to all from down under in OZ Scott

First, asking the same question more then once will not help your cause. As to number 3; learn to use info for some of your answers I.E. info cp will show at the end the you will get error message if the copy was _not_ successful. Every copy is verified and if _not_ successful will not complete. To compare two files use the diff command, info diff for more information. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
My apologies Ken, for repeating the question. This question was asked I recall on a KDE/Linux mailing list and everyone advised to ask it in a different forum Thanks for your reply Scott On Tue, 2006-10-31 at 07:32 -0500, Kenneth Schneider wrote:

OK, but it was either asked on this list before or on the factory list. Cross-posting is frowned upon and I just thought I would pass that info on to you. I hope the answers I gave helped. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Yes thank you, The amount of mailing list is very excessive and sometimes difficult to fathom. The reason why I asked the question in this forum was that the KDE/Lunix forum was inappropriate for this question. Personally I see no value in posting the same question to multiple lists at the same time and I trust the system is wise enough to knock back multiple addressed emails. I only think 2 lists are appropriate for things I don't know right now. That is like throwing mud at the wall and seeing what sticks - That is neither helpful nor constructive. This one for strictly Linux O/S type question such as this one was and the KDE/Linux list for questions relating to the use of a KDE application. I think I have worked out which to use and when now. Unfortunately every Distro has a wide number of applications and finding the correct audience or list for your question is a mine field. Unfortunately is hard being a new kid on the block. Stepping out of one environment where you were completely competent and comfortable in and diving into a different O/S and having you extensive experience count for nothing is difficult - perhaps that is why many don't want to change their O/S where they change from the master into the student and sometimes we forget.

I would like to extend a hardy welcome to you for embracing the world known as linux and hope you keep with it. At some point in the near future you'll whack yourself on the head and tell yourself "It's easier than I thought why didn't I get it last week (month, year)". Like everything else in life it's easy once you know how and once you know how it will be a lot of fun. Have fun learning linux. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Greetings: I recently installed Suse 10.1 and suspect I may have inadvertently activated the Mail Transfer Agent with YAST. I have since returned to YAST and set the MTA internet connection to none. However my incoming mail continues to be automatically picked up from my ISP POP account and is appended to the /var/spool/myname buffer. My Thunderbird email client bypasses the spool by connecting directly to the ISP thus I do not receive the appended email without manual file copy intervention. I wonder if anyone in this forum can give me directions for disabling the MTA which I presume is service that is automatically picking up and spooling my incoming mail? Many thanks in advance for any help!

Default MTA is postfix . now if accidentally you set the Yast-mail server then definitely the settings will be written in to the mail.cf file of postfix. Check yours postfix settings with main.cf if it contains lines to pull the mail using LDA (Local delivery Agent : procmail ) then comment it first . Then stop the procmail or fetchmail #rcfetchmail stop Again go to the Yast-MTA settings and stop the LDA settings else remove and simply keep the postfix on then else Change the postfix alias mail settings and keep alias for user root only and remove the lines indicating yours Actual Email id . i am using Thunderbrid for pulling my mails automatically so once above settings are done you will be get rid of the /var/spool/<user> mail box. LDA must be off . MTA doesnt matter. else local system messages will be stop . Thomas M. Alldread wrote:
