Find and Replace text

[LeppeRMessiaH]

Hello,
I wonder if anyone can help me with a script that searches and replaces or adds (if it doesn't find) a line of text in Hosts file.
I did a menu already but I ran into this and I can't seem to successfully do it.

I need it to search for "link.company.com" for example and replace the ip in front of it or add the ip along with link.company.com

Thanks in advance, I hope I made myself clear.

Here's a solution.

Replaces a line containing "findhost" with "prepend findhost". If not found, appends it to hostsfile.

With setlocal and endlocal, this is safe to insert into a script.

Code: Select all

setlocal enableextensions enabledelayedexpansion
setlocal

:: Options:
set "hostsfile=C:\...\hostsfile"
set "findhost=link.company.com"
set "prepend=123.123.123.123"

set found=
for /f "delims=] tokens=1*" %%x in ('type "!hostsfile!"^|find /v /n ""^&type nul^>"!hostsfile!"') do (
set toggle=
for /f "delims=" %%z in ('echo:"%%y"^|find "!findhost!"') do (
set toggle=1
set found=1
echo:!prepend! !findhost!>>"!hostsfile!"
)
if not defined toggle echo:%%y>>"!hostsfile!"
)
if not defined found echo:!prepend! !findhost!>>"!hostsfile!"
endlocal

Thanks a lot
Any way I can make it 'runnable' by non-admins?

By changing permissions, unrelated to DOS, so without admin permissions, not likely.

download gawk for windows, then use this

@orange, tried your code, got

Code: Select all

find: invalid predicate `'

For me it works well, at least on the admin account.

I tried it on your test file and it works fine. Maybe you could investigate.
