While saving a file I made a typo and performed the vi command ':w~' instead of ':w!' and I created a root '~' instance in one of my subdirectories. How do I remove this reference without wiping out the entire main /root /~ directory? Do I use unlink()?

At the moment I'm doing:
for i in mdx/[0-9][0-9].png; do cp $i ../../d_s_c/images/mdx ; done
But as well as the directory mdx, I also have other directories called ntt, etc.
How can I say 'For everything in a subdirectory, copy it across to the same subdirectory over at at ../../d_s_c/images'?

I've used mod_rewrite to rewrite my apache2 root (my.server.com/) to point to /var/www/drupal6/ instead of /var/www/. I also have a script installed in my cgi-bin (/usr/lib/cgi-bin) but since the rewrite I can't seem to access it. When I go to my.server.come/cgi-bin/test.pl, I get a page not found from my drupal.
Is there a way I can access my cgi-bin without resorting to accessing my drupal through my.server.com/drupal6/?
Background: I have installed drupal CMS which has a base address of my.server.com/drupal6/ as it resided in /var/www/drupal6/. However I wanted users to be able to access it as my.server.com/ so I added the following into my httpd.conf
Code:
NameVirtualHost *:80
<Directory /var/www/drupal6>
RewriteEngine on
RewriteBase /

I just noticed on my Ubuntu machine (ext3 filesystem) that removing write permissions from a file does not keep root from writing to it. Is this a general rule of UNIX file permissions? Or specific to Ubuntu? Or a misconfiguration on my machine? Writing to the file fails (as expected) if I do this from my normal user account.Is this normal behavior?Is there a way to prevent root from accidentally writing to a file (Preferably using normal filesystem mechanisms, not AppArmor, etc.)
I understand that root has total control over the system and can, eg, change the permissions on any file.My question is whether currently set permissions are enforced on code running as root. The idea is the root user preventing her/himself from accidentally writing to a file. also understand that one should not be logged in as root for normal operations.

$ mkdir backup && mv * backup/

Works, but issues a warning. Also exit code is 1.

View 6 Replies View RelatedI would like to know how can I get permission to subdirectories of a share other than what main share has. I do not want them to have same share I mean for example I share "sharetest" and it has full access for A and B and C groups but "sharetest/foo1" has read only access for A group and "sharetest/foo2" has read only access for B group and "sharetest/foo3" has read only access for all of them.
View 1 Replies View RelatedI have the following command that I run on cygwin:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv
I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each
/d/tmp/subfolder1/somefile.properties
/d/tmp/subfolder2/somefile.properties
/d/tmp/subfolder3/somefile.properties
/d/tmp/subfolder4/somefile.properties
so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:
/d/tmp/,subfolder1,<itssizein KB>
/d/tmp/,subfolder2,<itssizein KB>
and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv

I am looking to get some information on the version of Linux we are running. I was advised that it was 2.6.18-194.17.4.el5. When I did a search on this and it keeps telling me that is reference to a kernel info. Is this the Linux version or kernel info?

I do a bit of programming and tinkering with Linux so I have to refer to documentation a lot. As a result my eyes do get sore when reading through documentation on PC. Another problem is when tinkering and something goes wrong, either with Ubuntu crashing or loss of internet connection, I can't get access to the relevant document to fix it. Because of these, I was thinking of getting an e-reader, in particular, an Amazon Kindle as it is the only one I've seen sold locally as I don't like buying electronic goods online as it is a hassle with shipping if anything goes wrong.
I would like some advice. Is the Kindle worth having to view documentation and tutorials? Is it easy to reference relevant material through it's search facilities? Most important of all, can it connect to (Ubuntu) Linux through a usb port?
Does anyone know of a decent Operating System CLI cross reference website where I can compare diffent CLI commands against others? For example I have a MAC OS 10.6X running Darwin and I needed to know what the equivalent command using CentOS of rusers would be? It would be users running that same command at the MAC cli.

When I compile this code, I get the error: undefined reference to `sqlite3_open' I added sqlite3 package using the command 'apt-get install sqlite3'. Unfortunately the sqlite3.h header file was not installed in /usr/include, so I downloaded the SQLite3 dist., untarred it and copied the sqlite3.h file to /usr/include. I saw on a previous message that I would need to link the library. The only library file in /usr/lib is libsqlite3.so.0, so the command g++ -lsqlite3 still gives me an error.

Problem: Rather out of the blue upon login, from the time of entering password to the desktop, is MUCH slower. I have no splash enabled and there is some reference to AppArmour profiles (it sits there at this apparmour reference , then sits trying to load desktop). However, I have never configured apparmor. Finally, on last login, there was some sort of screen corruption prior to getting to desktop.

I'm trying to change to a subdirectory:
Code:
tony@advent:~/scratch$ cd Home-Arch
bash: cd: Home-Arch: No such file or directory
So I list the contents of the current directory:
Code:
tony@advent:~/scratch$ ls
duhome Home-Arch qcad_1.dxf qcad_1.svg runme stdout
OK, I assume I have mis-typed the subdirectory name in ways I cannot detect, so I copy the sub-directory name from the output of the 'ls' command, while within the terminal window, and paste it into the next 'cd' command:
Code:
tony@advent:~/scratch$ cd Home-Arch
bash: cd: Home-Arch: No such file or directory

I know a bunch of commands and I am comfortable using the terminal, I even set a powerpc server but I can't figure out how to remove epiphany on this new computer I'm setting up. I didn't install anything with tasksel. I installed gnome and xorg afterwards... I load it up and 'startx' just fine. then I check around for the programs that were installed. I lik'em gimp, lot's of utilities. gedit. anyway I find epiphany, which I have already established that I dislike, I immediately go to the root terminal (another nice program that comes with gnome) and type apt-get remove epiphany-browser-data the output says it will be deleting gnome... however I have researched and found these are simpy meta packages that don't really matter.... however under the section that states all the packages that will be removed by autoremove there is a huge list... I doubt these packages are safe to remove. how to remove epiphany without removing a huge amount of probably needed software
