Hi
I have a configuration file as follows

Maxusers 100
LimitConn 500
Unlimiteduse Y

I want to change the values for Maxusers,LimitConn to 10 and comment out Unlimiteduse(add a #) . The file should be like this

Maxusers 10
LimitConn 10
#Unlimiteduse Y .

Please let me know how to write a script for it .

Regards
Upilli

man vi too. Although perhaps it would be better to read some basics on the web first.

Hi

Or he could give us some details about his skills. Is possible to be only Unix newby, but knowing Perl, PHP, Ruby or something else from other system, which could be also a good choice for an one-liner.

Try...

awk '$1 ~ /^(Maxusers|LimitConn)$/ {$2 = 10}
     $1 == "Unlimiteduse" {$1 = "#" $1}
     {print}' file1 > file2
