file manipulation 1

[metro256]

Any recommendations for the following scenario?

I need a script that converts a single IP address to a hostname. This IP address is located in several different files in different directories.

Any help would be appreciated.

Thanks

as you say "several" files, it's probably easier to run the same script over each file, rather than write something that searches for the IP address in lots of places and does complicated things.

Create a script, called ip_fix.pl, like this:

while(<>){
s/123\.123\.123\.123/my.host.somewhere.com/g;
print;
}

Call the script like this.

ip_fix.pl < old_file.txt > new_file.txt

check the new file and then rename it so that it overwrites the old file. Mike
