How to Mount NTFS and exFAT Partition in RHEL CentOS

Mounting NTFS

Mounting NTFS partition in CentOS/RHEL will need a simple trick. Here is the step.
$] sudo yum install epel-release

$] sudo yum install ntfs-3g

Suppose if the name of the device is /dev/sda3 and /dev/sda4, then here is the command to mount it from the terminal
$] sudo mkdir /mnt/WinE

$] sudo mkdir /mnt/WinD

$] sudo mount -t ntfs-3g /dev/sda3 /mnt/WinE  $] sudo mount -t ntfs-3g /dev/sda4 /mnt/WinD
If your windows OS is running with any updates or under hibernation, the above command will not work, Here is the solution for that. You can open the drives under read only mode.

if you get the error like shown above, here is the command 

$] sudo mount -t ntfs-3g /dev/sda3 /mnt/WinE -ro o

$] sudo mount -t ntfs-3g /dev/sda4 /mnt/WinD -ro o
NB: Sometimes you need not type "-t ntfs-3g", if the libraries are there, without this attribute also, the disk will be mounted.

Mounting exFAT file system

exFAT is another filesystem supported by the Unix families like (Mac OS). CentOS has a way to 
customise for mounting the exfat filesystem.

$] sudo yum install scons gcc fuse-devel rpmbuild
$] wget http://download1.rpmfusion.org/free/el/updates/6/SRPMS/exfat-utils-1.0.1-1.el6.src.rpm
$] wget http://download1.rpmfusion.org/free/el/updates/6/SRPMS/fuse-exfat-1.0.1-1.el6.src.rpm

$] rpm -ivh fuse-exfat-1.0.1-1.el6.src.rpm exfat-utils-1.0.1-1.el6.src.rpm

$] cd
./rpmbuild/SPECS
$] rpmbuild -ba fuse-exfat.spec
$] rpmbuild -ba exfat-utils.spec

$] cd
../RPMS/x86_64/
$] rpm -ivh fuse-exfat-1.0.1-1.el6.x86_64.rpm exfat-utils-1.0.1-1.el6.x86_64.rpm

The following is optional.
$] ln -s /usr/sbin/mount.exfat /sbin/mount.exfat

Again you can click the icon in the explorer to mount the exFAT partition, in the terminal

$] sudo mount -t exfat /dev/sdb2 /mnt/WinC

Installation of TexLive 2019

Please watch the video for full installation



I used .iso file to download, the Total size is 3.3GB for Linux,

and i used the torrent file to download, it took me just 20 min to download the entire .iso file

Extract the .iso file to a folder and open a terminal

$] sudo ./install-tl
(it goes into a terminal mode, which is faster compared to the GUI Mode)

$] sudo ./install-tl -gui
after the installation, set the PATH, MANPATH and INFOPATH as suggested by LATEX

export PATH=$PATH:/usr/local/texlive/2019/bin/x86_64-linux
export MANPATH=/usr/local/texlive/2019/texmf-dist/doc/man
export INFOPATH=/usr/local/texlive/2019/texmf-dist/doc/info

put these lines in to the /home/pradeepkumar/.bashrc

$] gedit /home/pradeepkumar/.bashrc
We have installed TexLive 2019 and texstudio.

To install texstudio

$] sudo apt install texstudio
The look and feel of TexStudio looks like this image.

Implementing a new system call in Kernel version 2.6.32

A system call is used by application or user programs to request service from the operating systems. Since the user programs does not have direct access to the kernel whereas the OS has the direct access. OS can access the hardware through system calls only.The following files has to be modified for implementing a system call/usr/src/linux-2.6.32.5/arch/x86/kernel/syscall_table_32.S/usr/src/linux-2.6.32.5/arch/x86/include/asm/unistd_32.h/usr/src/linux-2.6.32.5/include/linux/syscalls.h/usr/src/linux-2.6.32.5/MakefileNew set of files to be createdCreate a new directory newcall/ inside the path “/usr/src/linux-2.6.32.5/” Create new files Makefile, newcall.c and put them in the /usr/src/linux-2.6.32.5/newcall/ folder Create new user files (in any folder of Linux) to test the system call
