Vim or vi is a text editor. It can be used to edit all kinds of plain text files, editing programs, and UNIX/Linux configuration files. Vim supports additional options and it includes a lot of enhancements above old good vi text editor.
Syntax highlighting is nothing but a feature of vi/vim text editors that displays text, especially source code, in different colors and fonts according to the category of terms.
Task: Turn on color syntax highlighting
Open a file, for example open existing file called file.c, enter:
$ vi file.c
Now press ESC key, type “: syntax on” i.e. type as follows:
:syntax on
C source code editing while syntax highlighting is on in vi or vim:
Task: Turn off color syntax highlighting
To turn it back off, press ESC key, type : syntax off
:syntax off
How do I make the syntax highlighting permanent?
You can edit ~/.vimrc file and add append vim command syntax on to it. This ensures that vim will start with color syntax highlighting option:
$ cd
$ vi .vimrc
Append the following line:
syntax on
Save and close the file.

Hey this Syntax-highlighting works!!
Looks cool
Thanks.
In vim editor you can use syntax enable too.
Inside vim in command mode press shift : and write syntax press space and press tab and vim go through out different syntax command
I believe that the exact syntax is “set syntax=on”. At least that is how it works for mine.
To me as well. set syntax=on is working and not just syntax=on
@ Bobby, while it may work, I’m guessing you have an extra command after typing vim filename, that is because it’s asking for extra info…and can be avoided by hitting enter the correct way is:
set ts=4
set sw=4
set spell
set spl=en
syntax on
set wrap
set ai
etc….
@Garratt thank you for including the set command list. It is a great edition to this good tutorial. It all worked for me on a Mac OS X Mavericks.
All of the obove suggestions may not work since on most flavors of linux vi is pointing to vim. unalias vi.
$ which vi
vi=vim
$ unalias vi
$ which vi
/bin/vi
FINALLY I got syntax highlighting turned on. I had no idea how to do it. It wasn’t in the man page at all or anywhere else I had looked online until I found it here. Thanks!
For Ubuntu, you probably have the package “vim-tiny” installed by default.
To check this run:
dpkg -l vim*So install the real vim with:
sudo apt-get install vimor
sudo apt-get install vim-fullOn Debian Etch I originally just had vim-tiny, but I now have:
[email protected]:infrastructure$ dpkg -l vim*Hey Vivek,
Thanks:) it’s working!!!!!!
I am using fedora 5.My editor is VIM 6.4.7.I wanted to highlight keywords of my C program.I tried adding “syntax on” to your $HOME/.vimrc file which is copied from /usr/share/vim/vim64/gvimrc.examples…
and I tried the above mentioned tips also….pls help
Hi,
This doesn’t work in vi. any idea why? i don’t use vim and is there any setup required to use vim?
Thanks,
Senthil
@Senthil
:syntax on and :syntax off don’t work in vi. They are features of vim. vi is ancient, emerging from work by George Colouris and Bill Joy circa 1973 to 1979. It had no color and no understanding of syntax at all. This was an epoch before color was available on computers (except for government supercomputers used to track incoming intercontinental ballistic missiles, perhaps). Vim arrived much later, the first versions appearing in the early 1990s.
Ref: http://www.softpanorama.org/Editors/Vimorama/history.shtml
On many systems, the vi command is linked to vim. So you may be using vim and not even know it. You could try doing this:
vi –v
And see what the version is. If it says something like mine:
VIM – Vi IMproved 7.4 (2013 Aug 10, compiled Aug 12 2013 00:27:34)
then you have VIM. However, if you are still not getting highlighting, then you might be using a compact version of VIM (vim-tiny). So see the post above from
rob on March 11, 2009 at 3:50 pm to find out more about that.
Good luck!
Thanks, this works for me on ubuntu 8.10
It’s great! Thanks.
I am using Vim on fedora.. How do you turn off yellow highlight between space (text) in vim file?
what command turn off yellow highlight?
use:
:noh
to turn it off
This worked for me
This worked for me. Thanks a ton. Saved a lot of my time.
thank a lot……….
I turned off the colorization. Whew. Now I would like to get rid of the highlighted
matching braces. When I put the cursor on an open curley brace it highlights that
brace and the matching closing brace. Rescue me!

Even I had searched online a lot before but nothing worked..thankfully I landed here today and it finally worked..:) Thanks
Hey. If you are using a dark background for your terminal you may want to
” set background=dark “
‘syn on/syn off’, instead of typing ‘syntax’, works as well in vim.
Imagine what your boss would think if he/she found out you were getting paid while typing
those three extra letters!!!

hi,
I am using fedora 13.I wanted to highlight keywords of my C program, i tried all the above told but i am still unable..pls help me out,I am new to linux
What kind of idiot decided that we need syntax highlight ?
I’m very glad to have found this blog and to have learned to use syntax off. Those colors were a profound interference for me.
Indeed. Thank you.
Some completely other kind of idiot than me, apparently.
Thanks! Worked well.
Syntax highlighting is a huge benefit to me. It makes commented and uncommented lines different colors in config files. Much easier for finding which options are enabled.
I’m colorblind, and the syntax highlighting just makes the code hard to read.
I hope the next version of VIM lets me specify what color I want for background and what color I want for foreground instead of requiring me to choose from their predefined templates.
Hey! Maybe VIM already lets me specify bg and fg colors! Does anyone know the syntax for the command?
All you could want to know about vim and syntax highlight:
http://vimdoc.sourceforge.net/htmldoc/syntax.html
I try. but i didn’t got it. its not working in my Linux OS.
I use Fedora 14.
Plz give me a help to solve this problem
1st checkl you have installed vim by connanding
yum install vim-enhanced
if you got message like “already installed and latest version
Nothing to do”
if not install it ,
then open your .c/ .cpp file and command
:set syntax=on
Thank you very much very helpful.
Its working Nice..!! Thank you..!!
If you use sudoedit to edit a file, vim won’t be able to determine what syntax to apply so you need to also do
hi, when i open a new .tex document, i have a different syntax than, when i open an already existing .tex document. I like the first one better, but typing :set syn=tex gives me the ugly one. Any ideas how i get the other one?
Thanks for the great tip!
how to compile c program in fedora 15?
Can anybody help?????
Hooray! Thanks, Rob who commented in 2009. I had syntax on and had adjusted the color settings, from 8 colors to 256, but the final key was to kill vim-tiny. Running Ubuntu and had installed vim-full but I was still apparently using vim-tiny. Just ‘sudo apt-get remove vim-tiny’ed. This post helped me with color settings http://stackoverflow.com/questions/3761770/iterm-vim-colorscheme-not-working
Thanks. The syntax highlighting finally works for me when I type :syntax on.
I use Vim Editor in Cygwin. 1.7.16-1(Latest version). But I am unable to make it default. I tried editing the $vi .vimrc. It just doesn’t work. Help would be appreciated.
One other piece of this puzzle, for those who are using the correct syntax to turn highlighting on, but are still not getting color: you might need to tell vim what syntax highlighting to use. It can’t always figure out the correct one.
For example, when editing a config file in vim, type
:set syntax=sh
That sets it to “shell script” highlighting. The syntax highlighting configs available are: c perl java html cpp sh csh
so if you’re editing a perl file, you’d type :set syntax=perl
hey..i m getting syntax comman not found
You have to do this inside of a file you are editing in vim, not from the command line before opening a file.
Cool. Good to know. Thanks.
I’m happy to turn the syntax highlighting OFF
It gets confusing with all the damn colors. I can never tell where the cursor is!
Now I need to turn off the colors that highlights EVERY DAMN MATCH when you search for text! Then that STAYS ON when you exit and return later.
Look, that’s a nice feature, but it deserves its own distinct command. Usually when I’m searching for something, I only want the NEXT one. And again, it makes it difficult to find the cursor, so I always end up making changes in the wrong place.
To turn off highlighting :noh
If anyone is still not getting colour or getting shades of grey (I was using securecrt) the doing :set term=ansi before :syntax on gave me colours. (Sinclair ZX Spectrum colours lol )
Thanks for the hint, I’ve been using vim in the terminal on my Mac for a while now and have wondered why everything was just black and white! Just put “syntax on” in my ~/.vimrc, and it worked right away. Cheers :)
Thanks
/etc/vim/vimrc is the path to the config on debian.
Uncommenting the syntax on line enables the functionality.
This all worked for me on a Mac OS X with Mavericks. I used the following options in my ~/.vimrc file:
1 syntax on –> for syntax highligting
2 set ts=4 –> for tab spaces set to four per tab character
3 set sw=4 –> Set the shift width to four spaces
4 set spell –> set spellchecking on
5 set spl=en –> Set spelling language to english
6 set ai –> Enable auto indentation
7 set nu –> Enables line numbers
You will notice I have line numbers set with ‘set nu’. I did not type in the numbers one through seven though they were put there by VIM. Then, when I copied and pasted the text it gave me line numbers!
Thanks to all who contributed to this post.
P.S.: When using the options from my post make sure to remove the line numbers and my comments that are all prefixed with ‘–>’ since they are not real VIM comments. I added them to this post after copying and pasting from VIM.
Is there a way to selectively disable syntax highlighting on a line-by-line basis, I mean shut it off only for a couple of lines here and there within a file, while keeping it on for the rest of the file I am editing?
Btw using ‘vim-gtk’ package under Debian sid.
Thanks for the simple explanation. it works.
Good article.
My 50 cents. You can redefine any color theme after “syntax on”
Now, all comments will be green, not a dark blue. Much clear.
Cheers!
Wow, this doc really helps !!! THANKS !!!
When I simply do “ls -l ” in one dir, some links show colors.
How can I turn on and off colors for “ls ” ?
I need all files , dirs listed white, while my background is black.
Thanks !
thank you very much it worked
This is nice !
Thank you
