First of all, can RedHat Linux Read/Write on FAT32 partitions?
Secondly, if it can, where do I go to access those partitions?
-
Yes. And, I dunno about Red Hat, but in Mandrake it's automatically mounted with the other drives under /mnt/
-
in the control center of kde you can choose to display mounted and unmounted partitions on the desktop, you might want to configure this for easy access to them. otherwise, you'll have to mount them in a folder... typically /mnt/dos or something.
-
You need to edit a file called /etc/fstab. In that file, there should be a listing of all devices that you have mounted. Let's use an example:
* Red Hat is on a dual boot with Windows on the primary harddrive
Run this command:
$ cat /etc/fstab
It should return something like this:
#/etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hdb1 / ext3 errors=remount-ro 0 1
/dev/hdb3 /media ext3 auto 0 0
/dev/hdb4 /home ext3 auto 0 0
/dev/hdb5 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto user,noauto 0 0
/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0
/dev/hda1 /windows/c vfat auto 0 0
/dev/hda5 /windows/g vfat auto 0 0
/dev/hda6 /windows/d vfat auto 0 0
/dev/scd0 /cdwriter auto ro,noauto,user,exec 0 0
In this example, I have two physical harddrives (/dev/hda and /dev/hdb), both of which are partitioned. (/dev/hda1 = "C:" on Windows, whereas /dev/hdb1 is the / directory of my Linux drive). I had to manually input the information into /etc/fstab to make it automount upon the initial, and only, boot of Linux, as specified in the <options> column. You don't really have to worry about the <dump> and <pass> fields for now. What I have will work, for the time being.
When setting up /etc/fstab, you have to not only declare the file system type (in this case vfat), and its representation in the /dev directory (in this case /dev/hda1), but you must also specify a mount point (in this case /windows/c). Basically, what this means, is that you have to make mountable directories where you would like to access your mounted filesystems. In my case, I ran this command after I editied /etc/fstab:
$ mkdir -p /windows/c # and then all other Windos drives
Once everything was delcared, you can run:
$ mount /windows/c
Then run this command:
$ cd /windows/c; ls -la
You should be able to see the entire DOS tree, the directories, files, and permissions.
After that, you can set up "shortcuts" to your Windows drives on your GNOME/KDE/whatever desktop.
Hope that helps (http://smile.gif)

If first poster was asking for future reference then I wouldn't worry too much about the info overload, Red Hat will do it all automatically during the install.

What does "grep" mean and how is it used?

easy, lets say i have some files in a directory:
cparty1 cparty2 cparty3 cb1 cb2 cb3
i only want to view the ones with party, so
ls | grep party
i can't think of how to explain it without using an example.
-
Interesting Unixologism.
-
grep searches through specific files or standard input and prints any lines that match a particular pattern. It uses regular expressions so the pattern matching is very powerful.
A simple example:
grep '^fish[^ ]' ./*
will search through all files in the current directory and output any lines that begin with "fish", followed by any character other than a space.
-
Or for example if I want to find all mp3 files on my hard drive to convert them to ogg files I just:
ls -R /home | grep mp3
ls lists all the files on my home dir with -R.
The pipe redirects that output (my list of files) to grep.
Grep only shows me the ones with the phrase "mp3" in them, so I get list of files which are mp3s.
Or another example:
cat ~/telephonenumbers.txt | grep Fred
Fred Bloggs 60 123 456 789
-
Actually, since both of those examples given refer to finding files, I think it's worth mentioning that the more logical solution would be to use the 'find' command.
e.g.
find /home -name '*.mp3'
And just another small point about this:
cat ~/telephonenumbers.txt | grep Fred
Rather than piping the output of cat into a command, it's preferable to use redirection and do
command < ~/telephonenumbers.txt
as you don't then unnecessarily invoke another process (cat). Although with grep that isn't necessary either, as you could just do
grep Fred ~/telephonenumbers

1.get to know the name of your fat partion,such as /dev/hda1 or /dev/sdb1
2.mount it:
mount it to a folder in your linux system .
mount -t vat /dev/hda1 /mnt/fat_partion
3.access it as normal linux partion.
cd /mnt/fat_partion, and you will see all the files on your fat partion.
