sed命令不会替换"\“

Question

我使用sed将文件中的内容替换为字符串"dba01upc\Fusion_test“。替换后，我看到缺少'\‘字符。替换后的字符串为dba01upcFusion_test。似乎sed在替换..时忽略了'\‘。有没有人可以告诉我sed命令包含所有字符？

我的Sed命令：

sed -i "s%{"sara_ftp_username"}%"dba01upc\Fusion_test"%g" /home_ldap/user1/placeholder/Sara.xml

更换前: Sara.xml

<?xml version="1.0" encoding="UTF-8"?>
<ser:service-account >
<ser:description/>
<ser:static-account>
<con:username>{sara_ftp_username}</con:username>
</ser:static-account>
</ser:service-account>

更换后: Sara.xml

<?xml version="1.0" encoding="UTF-8"?>
<ser:service-account>
<ser:description/>
<ser:static-account>
<con:username>dba01upcFusion_test</con:username>
</ser:static-account>
</ser:service-account>

谢谢

Answer 1

sed -i 's%{sara_ftp_username}%dba01upc[\]Fusion_test%g' /home_ldap/user1/placeholder/Sara.xml
# or
sed -i 's%{sara_ftp_username}%dba01upc\\Fusion_test%g' /home_ldap/user1/placeholder/Sara.xml
# or
sed -i "s%{sara_ftp_username}%dba01upc\\\Fusion_test%g" /home_ldap/user1/placeholder/Sara.xml

转义\ (如果使用双引号，则为两次)

Answer 2

试试这个：

sed -i "s%sara_ftp_username%dba01upc\\\Fusion_test%g" /home_ldap/user1/placeholder/Sara.xml
