If you only need to view the file, I would use cat and grep....

Code:

cat file.txt | grep -v '#'

Do you want to remove all of the comment lines?

dhammika · 09-30-2005, 09:34 PM

no ... just display the uncomments ..and edit them etc...

if not possible how can cat grep removing the bank line ( Referring to you previous solution)

I'm not sure why you would want to remove all comments and / or blank lines. If that is what you want to do, it may be easiest to put it into another file.
For example:
To get rid of all lines which start with # ( comments ) might look like this...
cat file.txt |grep -v "^#" > file1.txt

and to get rid of all blank lines might look like this...
cat file.txt |grep -v "^$" > file1.txt

problem is squid.conf is little large only few lines actually need to config.

any other trick to jump to uncomments line when navigating the vi

thanks

Ok, I got it now.
Unfortunately, I didn't find any way to view lines that don't start with # .

The best hope I saw was to jump to end of paragraphs with the } .
