Question

我有一个文件如下：

["2015.01.07 10:06:24 UTC","2015.01.07 10:06:34 UTC","2015.01.07 10:06:48 UTC","<a href='/jobhistory/job/job_1418436639844_231528'>job_1418436639844_231528</a>","PigLatin:agg_daily_total_searches_and_unique_searc","data_svc","marathon","SUCCEEDED","1","1","0","0"],
["2015.01.07 10:06:28 UTC","2015.01.07 10:06:35 UTC","2015.01.07 10:13:28 UTC","<a href='/jobhistory/job/job_1418436639844_231529'>job_1418436639844_231529</a>","EndorsementsPendingImpressionEvent-c1201ed1-fb23-4","kafkaetl","marathon","SUCCEEDED","1","1","1","1"],

我需要分别从每行的开头和结尾删除[和],。

Answer 1

您可以尝试以下sed命令。

sed 's/^\[\|\],$//g' file

^断言我们处于一条线的起点，$声称我们处于一条线的末尾。由于基本sed使用BRE（基本正则表达式），因此您需要转义|符号以便像逻辑OR运算符一样运行。

示例：

$ cat ri
["2015.01.07 10:06:24 UTC","2015.01.07 10:06:34 UTC","2015.01.07 10:06:48 UTC","<a href='/jobhistory/job/job_1418436639844_231528'>job_1418436639844_231528</a>","PigLatin:agg_daily_total_searches_and_unique_searc","data_svc","marathon","SUCCEEDED","1","1","0","0"],
