linux - 使用 sed 命令插入一行

Question

文件中的文本如下所示:

[homes]
        comment = Home Directories
        path = 
        browseable = 
        writable = yes
        valid users = %S
        valid users = MYDOMAIN\%S

[printers]
        comment = All Printers
        path = /var/spool/samba
        browseable = no
        guest ok = no
        writable = no
        printable = yes

我希望输出为:

[homes]
        comment = Home Directories
        path = /data
        browseable = yes
        writable = yes
        valid users = %S
        valid users = MYDOMAIN\%S

[printers]
        comment = All Printers
        path = /var/spool/samba
        browseable = no
        guest ok = no
        writable = no
        printable = yes

我正在使用这个命令:

sed -i "\#path# s#.*#& /data#" file

它对路径所在的文件中的所有位置进行更改。

谁能帮我解决这个问题？

Answer 1

sed '/path[ ]*=[ ]*$/s#$#/data#'

在结束行之前有 path = 且有任意数量的空格的行上，将结束行 $ 替换为您的替换字符串。
