To: xiewenxiewen at gmail.com

比如说，有一个配置文件内容是这样的:


现在我想修改几个参数,ORACLE_HOME改成$ORACLE_BASE/product/9.2,ORACLE_SID改成s3,TZ改成"Asia/Singapore"


只用一条命令就可以做到:
cat <<'EOF' |sed 's:^\(.*\)=\(.*\):s|^\1=.*|\0|g:g'|sed -i -f - .screen3profile
ORACLE_HOME=$ORACLE_BASE/product/9.2
ORACLE_SID=s3
TZ="Asia/Singapore"
EOF


哦耶，再也不用费事调用vi修改文件了，真厉害呀我
