[英]How to replace text in text file using .SH file script?
So I want to create a script that takes 3 arguments - path to file, exact word to replace and with what to replace it. 因此,我想创建一个包含3个参数的脚本-文件路径,要替换的确切单词以及替换内容。 How to create such thing?
如何创造这样的东西?
Generally I want6 it to have api like sudo script.sh "C:/myTextDoc.xml" "_WORD_TO_REPLACE_" "WordTo Use"
通常,我希望它具有
sudo script.sh "C:/myTextDoc.xml" "_WORD_TO_REPLACE_" "WordTo Use"
这样的api。 sudo script.sh "C:/myTextDoc.xml" "_WORD_TO_REPLACE_" "WordTo Use"
您不需要脚本,一个简单的sed就可以了(如果您在cygwin或POSIX兼容操作系统下运行):
sed -i '' 's/_WORD_TO_REPLACE_/WordTo Use/' "C:/myTextDoc.xml"
Something like this? 像这样吗
#!/bin/bash
sed -e "s/$2/$3/g" <$1 >$1.$$ && cp $1.$$ $1 && rm $1.$$
Alternatively, you can use the single command 或者,您可以使用单个命令
sed -i -e "s/$2/$3/g" $1
as Yan suggested. 如严所言。 I generally use the first form myself.
我通常会自己使用第一种形式。 I have seen systems where
-i
is not supported (SunOS). 我见过不支持
-i
系统(SunOS)。
This will replace all instances of the second argument with the third, in the file passed as the first. 在作为第一个传递的文件中,这会将第二个参数的所有实例替换为第三个参数。 For example,
./replace file oldword newword
例如,。/
./replace file oldword newword

$ ruby -i.bak -ne 'print $_.gsub(/WORD_TO_REPLACE/,"New Word")' /path/to/file
