我有一份名单。
server
server.apple.com
server.apple.com
server
server.apple.com
现在,我要在“服务器”的行文中加上“......”。 我尝试:
sed -e s/server/server.apple.com/g
您可以使用:
sed s/^server$/server.apple.com/g
你也不需要<代码>-e的论点,因为这只是基本标准。
If you want case insensitive search for server (also match SERVER and SErvEr) you can use the I function, however it is not supported by various versions of sed:
sed s/^server$/server.apple.com/Ig
If you don t have a sed version that supports I you can use:
sed s/^[Ss][Ee][Rr][Vv][Ee][Rr]$/server.apple.com/g
sed s/^server$/server.apple.com/g inputfile
