Alternative to perl search and replace

FirmbIT · 11-06-2006, 09:01 PM

I'm writing a script and am trying to do a Perl search and replace in a file by replacing something in the file with a variable but it is turning the variable blank and replacing it with nothing. Here is the code:

perl -pi -e 's/hostname/$hostname/g' /etc/nagios/configs/$hostname/host.cfg

Is there another way to do this? Maybe sed?

Thank you for the help in advance.

I believe all you need to do is quote your variable such as:

Code:

perl -pi -e 's/hostname/'$hostname'/g' /etc/nagios/configs/$hostname/host.cfg

or using sed:

Code:

sed 's/hostname/'${hostname}'/g' /etc/nagios/configs/$hostname/host.cfg

Hope this helps
