Here are some indispensible linux tips and tricks which are must for new and experienced users alike.Lets have a look at them-
Speeding up your hard drive
Get faster file transfer by using 32-bit transfers on your hard drive
Just add the line:
hdparm -c3 /dev/hdX
to a bootup script.If you use SuSE or other distros based on SYS V,
should work for you. This enables 32-bit transfer on your hard drive. On some systems it can improve transfer performance by 75%. To test your performance gain, type:
hdparm -t -T /dev/hdX
More DOS-like commands Many people are moving to Linux because they miss the stability of good old DOS. In that light, many users are typing DOS commands (which originated from UNIX in the first place) that look fine but cause errors. The command "cd.." in DOS is perfectly valid, but Linux balks. This is because "cd" is a command, and any parameter for that command must be separated from the command by a space. The same goes for "cd/" and "cd~". A quick fix is here.
Use your favorite text editor in your home directory to edit the file ".bashrc". The period is there on purpose, this hides the file from normal ls display.
Add the lines:
alias cd/="cd /" alias cd~="cd ~" alias cd..="cd .."
And I usually add these...
alias md="mkdir" alias rd="rmdir -i" alias rm="rm -i"
and my first and still favorite alias...
alias ls="ls --color"
alias is a powerful tool, and can be used in the .bashrc script as well as from the command line. You can, if you want to spend the time, create your own group of shell commands to suit how you work. As long as you put them in your .bashrc file, they'll be there everytime you log in. Note that if you frequently log in as root, you might want tocopy /home/username/.bashrc to /root/.bashrc to keep yourself sane.
Setting your timezone The timezone under Linux is set by a symbolic link from /etc/localtime to a file in the /usr/share/zoneinfo directory that corresponds with what timezone you are in. For example, since I'm in South Australia, /etc/localtimeis a symlink to /usr/share/zoneinfo/Australia/South. To set this link, type:
