linux – 用AWK增加日期几天和几个月

大家好,我需要你的帮助.我有一个文件“test.csv”,我想增加“6个月”和“10天”的日期,以便我得到以下输出：

test.csv：

"000001","TEST1","2013-05-07 16:02:07","ACTIVE"
"000003","TEST3","2013-05-09 16:02:07","ACTIVE"
"000004","TEST4","2013-05-10 16:02:07","ACTIVE"
"000005","TEST5","2013-05-11 12:02:07","ACTIVE"

输出test-increment-10days.csv：

"000001","ACTIVE","2013-05-17 16:02:07"
"000003","2013-05-19 16:02:07"
"000004","2013-05-20 16:02:07"
"000005","2013-05-21 12:02:07"

输出test-increment-6months.csv：

"000001","2013-11-07 16:02:07"
"000003","2013-11-09 16:02:07"
"000004","2013-11-10 16:02:07"
"000005","2013-11-11 12:02:07"

我用这个命令试了一下：

awk -F””,”” ‘{{ cmd=”date ”+%Y-%m-%d %T” -d ””$3″ +10 days””; cmd | getline datum; close(cmd); print $0 “,””datum”””}}’ test.csv > test-increment-10days.csv

awk -F””,”” ‘{{ cmd=”date ”+%Y-%m-%d %T” -d ””$3″ +6 months””; cmd | getline datum; close(cmd); print $0 “,””datum”””}}’ test.csv > test-increment-6months.csv

但我得到了错误的输出.

测试递增,10days.csv：

"000001","2013-05-08 16:02:07"
"000003","2013-05-10 16:02:07"
"000004","2013-05-11 16:02:07"
"000005","2013-05-12 12:02:07"

测试递增,6months.csv：

"000001","2013-06-07 16:02:07"
"000003","2013-06-09 16:02:07"
"000004","2013-06-10 16:02:07"
"000005","2013-06-11 12:02:07"

“test-increment-10days.csv”中的日期仅增加一天,而“test-increment-6months.csv”中的日期仅增加一个月.希望有人可以提供帮助.
