By default, some of the application installation provide you a sample configuration file. Usually the sample of configuration will end with name like *.sample, *.default and so on. Let say you have 20 of *.sample files and it will take you some time to copy, move or rename one by one. Lets do some quicker way which will save more time.
Create a sample file file random name ended with *.sample. Example
touch apple.sample.cfg touch microsoft.sample.cfg touch php.sample.cfg touch config.sample.cfg touch apache.sample.cfg touch mysql.sample.cfg touch pgsql.sample.cfg touch cacti.sample.cfg touch wordpress.sample.cfg touch jessicaalba.sample.cfg
Now you have all the sample configuration, you are going to use them. Are you going to copy one by another and change the same with .cfg prefix? We can do it, in a better and faster way.
Make a new directory to store all the sample file
mkdir sample cp *.sample.cfg sample/
After that, go to sample directory and copy the files to a location
cd sample for d in `ls *.sample.cfg`; do cp $d `echo $d | sed s/sample.cfg/cfg`; done
That one simple line will easily save you 1-2 minutes.
