You can use SED's range selector for that:
您可以使用SED的范围选择器:
sed '19,33{s/google/facebook/}' file
This will run the substitution on lines between 19 (exclusive) and 33 (inclusive)
这将在19(不包括)和33(包括)之间的行上进行替换
Note this will only replace the first occurrence of google
on each line, you can use the g
-modifier to change this behavior:
请注意,这只会替换每行上第一次出现的google,您可以使用g-modifier更改此行为:
s/google/facebook/g
