I keep creating practice perl scripts in a linux directory using vi <filename> and need to chmod 751 <filename> before I can run it as I wish to. I'm sure there is a simple way to default my permissions or config them at creation, but I'm not familiar with it ayuda me por favor.

View 1 Replies View RelatedI have some basic experiencing creating simple scripts/making directories/changing permissions/etc. but I'm stumped on this one.
I have two linux boxes. I have a script set up on box 'A' to SCP into box 'B', grab a copy of a database backup and store it on box 'A'. It looks like this:
scp root@X.X.X.X:/blah/blah/blah/dump.23.gz /home/blah/DB_Backups/
I have generated a public key on box 'A' and placed it into the authorized_keys file on box 'B', so a password is not required and the file copies over successfully when the script is run. On to my problem...
I need to know what date the 'dump.23.gz' file was originally created when I'm viewing it after it's been copied to box 'A'. If I ls -l on box 'A' it only shows me the date it was created on box 'A' when it was copied.
What would I need to add to my script to append the backup's original creation date on box 'B' to the filename so that when it gets copied to box 'A' I know when the backup was created on box 'B'. I'm sure this is probably confusing. I've done lots of searching and can only find information on how to append the current date and time to a file name. I need to append it's original creation timestamp to the filename when it copies over.
I was wondering if there is a command to show a real-time creation of files. I basically executed a command that will created thousands of files and takes a long time. I want to check if it is still creating additional files or if ti got frozen.
View 3 Replies View RelatedI'm just starting out with shell-scripting, but having a problem with making new text files with the touch or cat > commands.
What I've been doing is touch testfile1.txt
Also, I've tried cat > testfile1.txt (text)
Console reports "bash: text1.txt: No such file or directory. Consfusingly, it works fine in the home-directory. But if I move the file to where I want it, I can no longer view, edit, etc. it.
When I view a file in Linux with the 'less' command, I often only get a ":" prompt in the bottom left corner. There's no clue about how long the file will be, or at which location I am currently. When reading manpages with 'man', there's a file title and line number in that corner. And once I hit the end of the file, there's even a percentage shown. I've learned about 'less -m' but it's not that powerful. So what does 'man' differently from 'less'? They appear to be the same viewing programme, except for that file information difference.

View 4 Replies View RelatedBack in the old days of PC-DOS 3.1, computers are much simpler than today's. I can learn a lot of how File System works with tools like PCTools, Norton Disk Doctor, and [URL]. Have been working exclusive in corporate database application area for over a decade, my knowledge of how these stuff work is diminishing. Standard-clean OS (Windows, Linux) installation is all I can do now. And it starts to cause me many data-loss troubles, when I have to perform something that I don't have much insight, such as install and remove peer linux os or move and resize partitions.
I'm looking for books, web resources, or communities where I can educate myself on how various file system works, for which I can have in-depth answer to questions such as:
How to remove ubuntu and grub2 ? (I recently did that, but with a lot of frustration when I was not really sure what I was doing and confront with some scary error message like "Missing BootMgr" What kind of disk-partitioning operation can be performed non-destructively, and why ? What is Active partition ? Primary Parition ? Extended Partition ? How it stored on the disk. There are many free partitioning tools out there, which one is safe to used ? NTFS, Ext3, Ext4, .. What the differences ? How to choose it wisely.
Go to a specified directory and open a log file and parse out specific information and dump it into another text file.

I want to automatically allow all users read execute or write permissions on everything created by a specific user, is this possible?

Is ACL the best way to ensure the permissions of newly created files? Basically I have a directory: /data/department
I've done chmod g+s on it so the group is correct on new files but I want new files to also have 775 permissions so the rest of the group can access these files fully. Currently they are created with the default 755 (which I want still every where out side of /data/department ).

View 7 Replies View RelatedI'm trying to install Ubuntu alongside windows 7 on my machine, and currently I am having difficulty doing so.Upon initial boot of the LiveCD,it says the installer has encountered an unrecognized error and just goes straight to desktop environment. From there, I can restart the installer just fine but here is where the trouble starts.
Currently, I have a 2TB RAID 0 array utilizing 4 500GB Seagate barracuda SATA II drives. The controller is an nForce 780a NVRaid. I currently have two NTFS partitions for windows. One 150GB primary partition for C:, and another 781GB D: for the storage of games, music and movies.When I try to manually setup the partitions in the Ubuntu installer, I do it like this.
- 200MB ext2 primary partition for /boot
- 150GB xfs logical partition for /
- approx 750GB xfs logical partition for /home (You've probably figured out I'm following the same C: and D: scheme as in windows)
- 8192 MB partition for swap
I then proceed with the install. I see the progress bar complete for the boot partition, but then at about 7% for / it stops and gives a message saying partition creation has failed. I even tried using different filesystems like ReiserFS and Ext4. Same thing every time. I am running a 64bit quadcore system BTW if that is of any importance.
My problem is that I want newly created files to be 775 but they are 644 according to ls -l tho user that created can still write to file while other user in same group can't.
Current umask is 002.
Can't findout how to get newly created files to be 775. What should i do make all new files created by a user to be 775?
net book had some issues with windows, so i had to format its hard drive. i put in the ubuntu live image (usb) (yes i md5summed it, its fine) and i tried installing it using the guided partition (using the whole disk) and i tried setting it up manually, but regardless of what i try, when it attempts to format it to the necessary filesystem, it fails at 5% without fail. even IF i use GParted.
View 4 Replies View RelatedI know newer filesystems support crtime values, even to nanoseconds granularity. Ext4 does it, and NTFS mounted via ntfs-3g should expose it. Still, what is the command to get these values??
getfattr -d <some file>
gives me zero results, and as far as I know ls does not have means to access creation time.
getfattr -n ntfs_crtime /mnt/<some ntfs fs> gives me "Operation not opermitted"..?
I know about the difference between ctime=inode change time and crtime=creation time/file birth time. I want to migrate a NTFS partition to Ext4 without losing the creation dates...
why sadc (a front end for sar data collection) would append a "?" to the output file when run from cron? And more particularly, how should I correct it? I have a RHEL 5.4 system which is doing this.e.g./usr/lib64/sa/sadc -d 10 6 /tmp/test produces output file /tmp/test when run from the command line but when run from cron the file produced is called "/tmp/test?"
Normal system logging with sysstat, which uses the same sadc command (with a couple of other options, and none of the options -d, -F, -L affect this behaviour), produces output files /var/log/sa/sadd where "dd" is the day of the month. There does not seem to be any control over this within the sysstat start-up scripts, other than use of option "-" to generate standard output files, so I expect that the dd is being done within the code. Is this associated with the "?" ?.Whatever is going on, the appended query seems to get added to everything as it still happens if I make the output file /tmp/test_$(/bin/date +\%d).Is this a bug or am I missing something fundamental about cron?
How would you make NIS user information override local user information on client systems? This is what I think is right? Add nis on the passwd registration file on the second line Is this correct?
