我有"我爱Suzi和Marry",我想把"Suzi"改为"Sara".
#!/bin/bash
firstString="I love Suzi and Marry"
secondString="Sara"
# do something...
结果必须是这样的:
firstString="I love Sara and Marry"
在我的程序中,我想首先获取用户输入,并\在每个之前插入一个/
所以我写这个,但它不起作用.
echo "input a website"
read website
sed '/\//i\/' $website
我们想删除 ^[所有的转义序列.
sed不工作,并给我们这个错误:
$ sed 's/^[//g' oldfile > newfile; mv newfile oldfile;
sed: -e expression #1, char 7: unterminated `s' command
$ sed -i '' -e 's/^[//g' somefile
sed: -e expression #1, char 7: unterminated `s' command
当我在Jenkins中运行maven目标时(例如"mvn test"),由于出现的颜色控制字符,日志很难读取(参见下面的示例).反正有没有删除颜色格式？
