fetchrmver.sh

一个awk和bsh混合编程的例子

#!/usr/bin/ksh

VERSION=$1
COMPATIBLE_MAP="CompatibleMap.cfg";

VERSION_TMP=${VERSION#*\{};
VERSION=${VERSION_TMP%*\}};

backComp="";
fetchRMVer()
{
	if [ ! -r $COMPATIBLE_MAP ]; then
		echo "ERROR: $COMPATIBLE_MAP not exist.";
		exit 1;
	fi
	
	backComp=`awk '
		/^ *\t* *#.*$/ {;}
		/^ *\t* *$/ {;}
		/^V/ {
			version_map[$1] = $2;
		}
		END {
			printf "%s\n", version_map[isn_version];
		}' isn_version="$VERSION" $COMPATIBLE_MAP`;
	backComp="{"$backComp"}";
}
