使用sed-r替换文件的shell字符串

但它具有实际价值

{r ${TEST_DIRECTORY}/check.html\n d}

---

单引号内的变量不会由Bourne shell展开。请改用双引号：

{r dir1/dir2/check.html\n d}

sed-i$'/{r'${TEST_DIRECTORY}$'/check.html\n d}'${TEST_DIRECTORY}”/result.html

您需要双引号，如下所示：-

sed -i  $'/<!--Change here-->/ {r '"${TEST_DIRECTORY}"$'/check.html\n d}' "${TEST_DIRECTORY}"/result.html

sed-i$“/{r${TEST\u DIRECTORY}/check.html\n d}${TEST\u DIRECTORY}/result.html”

sed -i  $'/<!--Change here-->/ {r '"${TEST_DIRECTORY}"$'/check.html\n d}' "${TEST_DIRECTORY}"/result.html

sed -i  $"/<!--Change here-->/ {r ${TEST_DIRECTORY}/check.html\n d}' ${TEST_DIRECTORY}/result.html"
