问题描述
My Linux file contains of over 4000 lines of code similar to this:
我的 Linux 文件包含 4000 多行与此类似的代码：
[INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:57','Electrolux', 'abandoned', '1609507904.86839', 'ROUTING_SCRIPT', 'Electrolux', '01008367900', '886123', 'CALL')]
[INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:59','Electrolux-Inst', 'queued', '1609507878.86832', 'VIRTUAL', 'Electrolux', '01552050703', '886123', 'CALL')]
[INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:59','Electrolux', 'distributed', '1609507878.86832', 'ROUTING_SCRIPT', 'Electrolux', '01552050703', '886123', 'CALL')]
[INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:59','Electrolux-Inst', 'distributed', '1609507878.86832', 'VIRTUAL', 'Electrolux', '01552050703', '886123', 'CALL')]
I need linux command(s) to delete the square brackets [ ] from the file so that it looks something like this:我需要 linux 命令从文件中删除方括号 [ ]，使其看起来像这样：
INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:57','Electrolux', 'abandoned', '1609507904.86839', 'ROUTING_SCRIPT', 'Electrolux', '01008367900', '886123', 'CALL')
INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:59','Electrolux-Inst', 'queued', '1609507878.86832', 'VIRTUAL', 'Electrolux', '01552050703', '886123', 'CALL')
INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:59','Electrolux', 'distributed', '1609507878.86832', 'ROUTING_SCRIPT', 'Electrolux', '01552050703', '886123', 'CALL')
INSERT INTO DATAMART_QUEUE_DETAILS(EVENT_TIME,QUEUE,EVENT,TRACKNUM,QUEUE_TYPE,ASSOCIATED_ROUTING_SCRIPT,ANI,DNIS,CHANNEL_TYPE) VALUES ('2021.01.01 15:31:59','Electrolux-Inst', 'distributed', '1609507878.86832', 'VIRTUAL', 'Electrolux', '01552050703', '886123', 'CALL')
Finally, I want to insert these lines directly to MySQL query.最后，我想将这些行直接插入到 MySQL 查询中。

A cheap and cheerful way is一种廉价而愉快的方式是
tr -d '[]' < infile > outfile
Edit: I should add that this won't have the desired result if [ or ] occurs in the data.编辑：我应该补充一点，如果 [ 或 ] 出现在数据中，这将不会产生预期的结果。

Even though this question already has an answer, I'd like to share my own solution here:即使这个问题已经有了答案，我还是想在这里分享我自己的解决方案：
cat infile | sed 's/^\[\(.*\)\]$/\1/' > outfile
Explanation:解释：
-
s: substitute commands/regexp/replacement/flagss: 替换命令s/regexp/replacement/flags -
^: start of string^: 字符串的开头 \[: The literal character[\[：文字字符[-
\(.*\): A group that captures everything\(.*\)：捕获所有内容的组 \]: The literal character]\]: 文字字符]-
$: end of string$: 字符串结尾 \1: text in the first capturing group (\(.*\))\1：第一个捕获组中的文本（\(.*\)）
EDIT: in fact, this solution works even if there are '[' or ']' inside the input编辑：事实上，即使输入中有 '[' 或 ']' 这个解决方案也有效
