One line perl command
Does anyone know how I can add a variable to a one line perl command such as the following:
#! /bin/bash date=`date +%Y%m%d` perl -i -pe 's/(1\.1\.0\.).+/${1}${date}/' ./build_date I'd like the ${date} variable to be evaluated by the perl command. So that the perl command will read each line of the file ./build_date and replace each line that contains '1.1.0.yyyymmdd' with 1.1.0.${date}. |
