Question

脚本abc.ksh应该替换文件xyz.sql的值，如下所示

搜索字符串“％s_sitename截止日期”+％Y-％b-％e“”每当我们执行abc.ksh时，sysdate更改日期

s1='%s_sitename%[a-z][0-9]/-'
s2='%s_sitename%'"$(date "+%Y-%b-%e")"
sed -i 's/'"$s1"'/'"$s2"'/g' xyz.sql

每次使用sysdate更新abc.sql文件

"%s_sitename% as of 2016-Jun-22"

随着电流的到来，我得到如下的有线输出

Answer 1

s1='%s_sitename% as of [a-zA-Z0-9-]*'
s2='%s_sitename% as of '"$(date "+%Y-%b-%e")"
sed -i 's/'"$s1"'/'"$s2"'/g' xyz.sql

测试：

echo "%s_sitename% as of 2005-Apr-02" | sed 's/'"$s1"'/'"$s2"'/g'

输出：

%s_sitename% as of 2016-Jun-26
