I would like to create a folder based on the system date in BASH. This is what I have done:
mkdir $(date +"%d-%m-%Y")
And its working fine, the output is 18-11-2012 but I need to concatenate this date with the string backup_
This is the output I want backup_18-11-2012
try this:
mkdir "backup_$(date +'%d-%m-%Y')"
