                                Sed在指定行後添加字符串

1.原文檔

[root@lmzf ~]# cat svn.txt
develop = www,yuj,hzy,chent,wmw,hello,welcome

2.在develop行後面添加字符串“,golive”

[root@lmzf ~]# sed   -i   '/^develop/{s/$/,golive/}'   svn.txt

3.最終效果

[root@lmzf ~]# cat svn.txt
develop = www,yuj,hzy,chent,wmw,hello,welcome,golive
