To more about the problem

I could use cat setDomainEnv.sh | sed -e 's/MEM_ARGS="-Xms.*/MEM_ARGS="-Xms=256m Xmx=1024m"/' > setDomainEnv.sh_tmp , where as I want to the variable in sed. For example

replaceString="-Xms=${JVM_MIN} -Xmx=${JVM_MAX}" and assume JVM_MIN and JVM_MAX is being set already.

cat setDomainEnv.sh | sed -e 's/MEM_ARGS="-Xms.*/MEM_ARGS=${replaceString}/' > setDomainEnv.sh_tmp

This will not replace value ${replaceString} inside sed. Sed require double quote instead of single quotes to get variable replaced. However my string contains replaceString="-Xms=${JVM_MIN} -Xmx=${JVM_MAX}", so the below simply will not work.

cat setDomainEnv.sh | sed -e "s/MEM_ARGS="-Xms.*/MEM_ARGS=${replaceString}/" > setDomainEnv.sh_tmp

Please help on this.

lr_environment

LR_ENVIRONMENT.IN(1)					  LogReport's Lire Documentation				      LR_ENVIRONMENT.IN(1)

NAME

       lr_environment - Export Lire configuration in shell script form

SYNOPSIS

       eval `lr_environment`

DESCRIPTION

       The lr_environment command is used to import the Lire configuration in Lire shell scripts.

       All of Lire configuration variables will be written in a format that can be evaled by the shell.

       Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.

       The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
