例如:我有一个 txt 文件,例如:
文本(“你好”) 文本(“世界”) 文本(“曾经”) 文本(“再次”)
Aim to replace
hello with string_1,
world with string_2,
once with string_3,
again with string_4,
如何编写脚本?
perl -pi -e 's/hello/string_1/g;s/world/string_2/g;s/once/string_3/g;s/again/string_4/g' your_file;
上面的命令将进行就地替换。如果您希望输出到控制台,则删除“ i
”。
另一种方法是:
sed -e 's/hello/string_1/g;s/world/string_2/g;s/once/string_3/g;s/again/string_4/g' your_file
awk:
awk '{gsub(/hello/,"string_1");gsub(/world/,"string_2");gsub(/once/,"string_3");gsub(/again/,"string_4");print}' your_file
一个不错的技术是使用替换字符串的字典。就像是:
perl -pe '%x=(
"hello" => "string_1",
"world" => "string_2",
"once" => "string_3",
"again" => "string_4",
);
s/$k/$v/g while( $k, $v ) = each %x' input-file
