I'm a little bit confused with partitioning the filesystem in Linux. the difference between creating the file system with fdisk and mkfs (when formatting the disk). I can't clearly tell my problem, so please look at this picture:

Write a script that will take a list of filenames as arguments and output a count of how many of them are regular files, and how many of them are scripts (if the file is executable, it will be assumed to be a script file)
Counts always come back as 0

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive

This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;'
FIL=~/replication-`date +%F`.txt
MAILTEXT=~/mailtext.txt
touch $FIL
$CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.

For example I want a file to be processed by sed, and then overwrite the file with sed's output. I would try this:
Code:
sed '<regex goes here>' myfile > myfile
But it doesn't work as expected, instead it empties the file (I am thinking that as the first byte comes out of sed, it overwrites the whole file and sed has nothing more to do). How can I make this work?

Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up).

I had only Arch on an HDD.sda2 was "/".Now it's with Windows XP and sda2 is not a root any more but a container partition wich has sda{5,6,7} in it. I configured the dual boot and it works. It finds Arch and boots it, but not completely. Stops after some time and says: unable to determine the file system type of /dev/sda2. FSTAB is configured, sda{5,6,7} are on their places. So I can't boot Arch. XP boots correctly. What do I do with this error?Also it says: try adding rootfstype=your_filesystem_type to kernel command line.

How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?

I want to scan a particular directory recursively and run a particular command with each file as input. For this I am using "find /dir/path". I dont want to write any long script containing loop on the output of "find". I want a single command which will allow me to run a command on each file of the "find" command output.

I just wanted to edit crontab, So could anybody please tell me which is the real file of crontab, so I can manually edit that file using vi editor or nano. Or if that default editor is corrupted when I type "crontab -e", how can I change default editor before using "crontab -e" command. I will be waiting for your kind reply

I noticed when running "ps -ef" that there are a bunch of processes listed with brackets. ie "[process]". Some of them appear to be daemons and others look more like kernel modules? I haven't found a program directly associated with them and was hoping somebody could clarify this for me?
Also, if I run a search of the file system with sudo or as root, there is a directory in my home that returns a permission denied. I understand permissions but shouldn't operations as root be able to do/access anything on the system?

There is a problem with my Sony VAIO PCG-GRX670. My windows has crashed and I don't see any way to revive it without formatting. I have a 40 GB HDD, it is initially split into 18 and 22 GB (C: and D: ). The problem is that, whenever I try to access the HDD, whether I do it from Windows XP Live CD, Ubuntu Live CD or some utilities (like Norton Commander - like programs and Partition editors), it is either not recognized whatsoever, or recognized as a whole unpartitioned 40 GB drive, and I see only the contents of C:. They say that the amount of occupied space is about 37 GB, which is true if you sum the amount of occupied space on C: and D:. But, they dont recognize it as a split disk, and (the main part) I cannot access the data I have on D: . When I access the 40 GB file system on Ubuntu and run "fdisk -l", it gives:
Disk /dev/sda: 40.0 GB, 40007761920 bytes
255 heads, 63 sectors/track, 4864 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x21d565dd
Device Boot Start End Blocks Id System
/dev/sda1 * 1 4864 39070048+ 44 Unknown
The question is, is there any way to access the D: from Ubuntu, so I could backup my data from it onto a USB Hard disk?

I've a new external usb drive that was shipped formatted fat32. I wanted to convert this to ext3; so I performed a mkfs.ext3. I then noticed that fdisk was still reporting the usb drive as fat32 (even after reboot), but mount was reporting ext3: so I fdisk'ed the drive and change the partition's system id to 83 (Linux)
