Jun 10, 2011I have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has as its contents a single word, say wordone)
#!/bin/sh
for f in value.txt
do
echo $f
done
so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?

Jul 7, 2010I have two text files on Linux. One contains a list of valid IDs. E.g:
abcd
efgh
ijkl
etc.
The other contains a list of invalid IDs. But, some of these also appear on the list of valid IDs, in this example "efgh":
mnop
qrst
efgh
etc.
How can I easily construct a text file that contains all the lines from the invalid list that do not appear in the valid list? That is, I want to end up with a text file that has:
mnop
qrst
etc.
I'd like either some Linux commandline magic of some clever Vim trickery.

and want to create a new file from each line. With

Jul 27, 2010After my first installation/ version of Ubuntu 64, I performed a netstat and noticed I did NOT have any Active UNIX domain sockets as I do now. After doing some research, I found this is related to MYSQL and server services which I am in no need of running and nor do I want to run if not needed. So exactly what are these services used for, which app is creating this and why?
Is it possible to remove the app or processes if they are not needed? Killing these connections every time they attempt to establish would be rhetorical.

Aug 2, 2011At the moment I am using Hummingbird Exceed on a windows PC to display X windows from a Unix server. The actual Exceed tool I use is called 'hwm' which I believe is basically an pc based X Windows manager. I do not need to configure anything other than the client computer name, IP address and screen definition and the server will then allow a connection and display the X windows on the client. I was wondering if there is an equivalent application I can run using Ubunto as a client insted of a Windows PC?
View 1 Replies View RelatedUbuntu Security :: Understanding Unix Style Permissions
Jul 20, 2010On Windows, you can go to a file's permissions and it's clearly stated who can do what. You can choose between individual users or groups such as 'everyone' or certain types of users such as 'domain users'. You could create a clear cut list of every single user/group on the system and what their permissions for a file are and have it neatly displayed in a list.On Unix, we have octal permissions and sticky bits. I understand the whole concept of rwxrwxrwx (777). The first three are what the file owner can do, the second is what the main group the user belongs to can do, and the third is what other users can do.
But, when you view a file's permissions you are only getting the permissions as they apply to the user that owns the file. For example, as I understand it, if I viewed a file that only the root user had rwx permissions on and everyone else could only read. The permissions would show up as rwxr--r-- (744). But, those same permissions would show up to any user as 744 as well. Since the last 3 characters are what applies to "other users" (pretty vague). How would someone know what users in particular those permissions apply to? There could be one "other user" that can rwx that file and another "other user" that can't.Also, why just stop with the main group? What about other groups? A the user Foo's main group he belongs to might be Foo. But he could also belong to the groups Boo and Zoo, which belong to other users and would give him full rwx permissions over Boo and Zoo's files just as if he were Boo or Zoo.
Then you have the whole sticky bit thing that makes it so that files can be owned by the same person and at the same time be made use of (to varying degrees) by other users. To chmod the UID you'd chmod 2777 or for GID 4777 (just an an example). I did this for a file and it allowed a standard user account who was previously unable to run the command to be able to run it. But, how can that work when I didn't anywhere specify what particular user (or groups of users) that sticky bit applies to?
I'm confused about this whole thing to the point that I'm not even sure exactly what questions I should be asking or even if my examples are even 100% correct. I just sort of ranted about some specific things that floated to the top of my head. Permissions are easy to understand when your running a Unix-like system on a single user desktop. Because the only users/groups you have are root, the single user, and various system users/groups that you don't really need to worry about. So a file with rwxr--r-- means that only the Root user (not even members of his group) can edit the file and you can't unless you use sudo. Because the "other user" in the last 3 characters always just means you. But, things seem to get a whole lot more complicated when you start adding in multiple users. Can someone explain this or link to a "for dummies" article that can explain all of this to me in a way that someone who's used to Windows style permissions can make a connection between the two OS families and their way of handling these things?
