Bash脚本用单引号和反斜杠替换单引号

Question

我有一个长字符串，其中包含单引号（＆＃39;）。我需要将它发送到mysql所以我试图替换＆＃34;＆＃39;＆＃34;用＆＃34; \＆＃39;＆＃34;在INSERT语句中的变量中。

示例：

"This is the first single quote ', and this is the second '"

应该成为

"This is the first single quote \', and this is the second \'"

我已经看过几个脚本替换和sed的例子，但是无法想出这个。 感谢任何帮助。

Answer 1

您可以使用sed "s/'/\\\'/g"：

echo "This is the first single quote ', and this is the second '" | sed "s/'/\\\'/g"

Answer 2

使用纯BASH字符串操作：

s="This is the first single quote ', and this is the second '"
s="${s//\'/\'}"
echo "$s"
This is the first single quote \', and this is the second \'
