I am trying to figure out how to remove this from config files:


the data in my file to get rid of is:

allow members of "remote"
range 192.168.1.0
filename "SYSTEM33E14"

I am trying to get rid of the complete line with:
--> filename "SYSTEM33E14"

I can comment out the line, however I am running into problems trying to match this to remove it?

I think maybe SED is the better choice---something like this:
replace SYSTEM33 with whatever is required to give an unambiguous result.

I need to remove the entire line completely, I tried this and it seemed to work.


sed '/filename/d' myfile.cfg > file.cfg

and it removed the line completely

I am still learning on this, is there a way when you use 'vi' inside the file to remove this?

thank you for the reply

Using the delete (d) command is equivalent to the form I showed. The real issue is to be sure that the address phrase is unambiguous.

I'm not familiar with vi, but I think it has similar capabilities.

Please use ***[code][/code]*** tags around your code and data, to preserve the original formatting and to improve readability. Do not use quote tags, bolding, colors, "start/end" lines, or other creative techniques.

The -v switch in grep reverses the match to exclude any lines containing the expression.

As pixellany said, in vi/vim, the command would be similar to the sed syntax, although you need to specify "g" (global) as well:

Incidentally, vi[m] can be used directly in scripting. If you run it with the -e and -s options, then you can pass it any EX mode commands from stdin.

('w' with no arguments will write the changes back to the original file, naturally.)

Although for this kind of thing the lighter ed is usually recommended instead.

And just to round out the list, here's an awk solution:
