hi,
sorry if i confused you...
you need to cd to the directory containing the OpenOffice binary... i believe
it unpacks itself into /usr/bin ... its a while since i've done this
though....
look for a binary called soffice - i think its actually inside a directory
called soffice (just to be really confusing)...
by the way, you'll need to be root to do this, so first type su and enter your
password...
once you've found the soffice binary then type
chmod 4755 soffice
(trust me those are the right numbers ;-)
chmod changes the permissions of a file... there's a good explaination at
http://www.linuxnewbie.org/nhf/Filesystems/File_Permissions.html
when you find the binary, try typing 'ls -al' first, and have a look at the
results, you should see something a bit like
miriam at hamish miriam]$ ls -al
total 17464
drwxr-xr-x 74 miriam miriam 8192 Aug 10 21:17 ./
drwxr-xr-x 4 root root 4096 Jun 16 02:25 ../
drwx------ 2 miriam miriam 4096 Jun 20 13:17 .AbiSuite/
drwxr-xr-x 4 miriam miriam 4096 May 14 01:40 alsaconfig-tp_files/
drwxr-xr-x 6 miriam miriam 4096 Jun 15 01:51 amSynth/
-rwxr-xr-x 1 miriam miriam 38 Aug 4 02:58 assignment2.py*
these are just some of my files... note the star beside 'assignment2.py' -
this indicates that its executable (i.e. a program)... your soffice binary
should have one of those too (and if you're using a Gnome terminal the
programs will be green).
okay, tell me to shut up if i'm telling grandmother to suck eggs now... or
just skip this bit ;-)
the stuff on the left that says drwxr-xr-x and all that tells you the
permissions of the group. the name next to it tell you who owns the program
and which group it belongs to... so the first line says that this directory
i'm in, or ./ is owned by me, but the directory above this one, or ../ is
owned by root.
the permissions split into four sections:
d rwx r-x r-x
the d stands for directory - if you see a slash instead of this, that means
this bit is blank - i.e. its a file. sometimes you'll see other stuff like s,
dont worry about this for now.
the next segment of three letters is the permissions for the owner, the
following three for the group, and the final three for any other users.
the soffice binary permissions probably should look like
-rwxr-xr-x
but at a guess, i think it must be saying
-rwx-r--r--
r stands for read, w stands for write, and x stands for execute. so if you
want to allow your groups and users to execute a program, you need to do
'chmod + x myProgram'.
the numbers are just a substitute for typing long strings.... usually you'd
just use three numbers, for user, group and other - i.e. chmod 755 myProgram.
its binary code -
4 stands for r
2 stands for w
1 stands for x
so the 7 is made by adding up 4+2+1 - so that means rwx (read write and
execute)
and the 5 is made from 4+1 - so that means r-x (read and execute only -
because you dont always want to allow a group to overwrite your programs!)
there's a wonderful explaination of this by Marcel Gagne, who writes for
LinuxJournal - i have his book Linux Systems Administration, and i'd highly
reccomend it for anyone learning Linux or sysadminning - or just for a good
read, it is *sooooo* funny! he's a really witty writer - which means its all
the more memorable and easier to read.
i cant seem to find his article on permissions on linuxjournal.com, but it
might be there somewhere... all of his articles are well worth reading, he
explains things so clearly (oh, and if you havent read him before... he
pretends he's a chef....!)
hope this helps, do ask more if you need to :-)
