我获得了一个以这种格式构建的数据库

10027|Chen|Ning|female|1982-12-08|2010-02-22T17:59:59.221+0000|1.2.9.86|Firefox
10995116908|Chen|Wei|female|1985-08-02|2010-05-2420:52:26.582+0000|27.98.244.108|Firefox

（注意第6栏中的T）

我的任务是输出数据库的行，日期从给定的dateA开始到给定的dateB。

到目前为止，我已尝试按第6列排序我的文件，排序为-M，具体为sort -k 6M -t "|" "file.dat"或sort -k6 -M -t "|"以及其他试验。

但没有任何反应。

我需要排序，因此我可以使用awk

指定开始和结束日期

最终，我没有看到这项任务有什么特别之处 - 只是简单的排序：

sort -k6,6 -t "|" file.dat

输出：

添加了一些额外的数据行，使搜索示例更容易看到：

我将使用以下输入参数定义bash脚本[search.sh]：

search.sh [--born_after <dateA>] [--born_before <dateB>] -f <dbfile>

`--born_after  <dateA>` : [optional] search for data records with field6 >= this search parameter; [format=YYYY-MM-DDTHH:MM:SS.sss+HHMM] [default=0000-00-00T00:00:00.000+0000]
`--born_before <dateB>` : [optional] search for data records with field6 <= this search parameter; [format=YYYY-MM-DDTHH:MM:SS.sss+HHMM] [default=9999-99-99T99:99:99.999+9999]
`-f <dbfile>`           : [required] data file to search

实际脚本：

$ cat search.sh
#!/bin/bash

# set default search dates, clear the dbfile variable:

dateA="0000-00-00T00:00:00.000+0000"
dateB="9999-99-99T99:99:99.999+9999"

unset dbfile

# simulate getopts so we can parse for long and short option names

while [ $# -gt 0 ]
do
        case $1 in
                --born-after)   dateA=$2                                   ; shift  ;;
                --born-before)  dateB=$2                                   ; shift  ;;
                -f)             dbfile=$2                                  ; shift  ;;
                *)              echo "Unexpected argument '$1'. Aborting." ; exit 1 ;;
        esac

        shift
done

# if we didn't get receive/parse a `-f <dbfile>` option then abort:

[[ "${dbfile}" = '' ]] && echo "Missing a dbfile. Aborting." && exit 1

# start by sorting dbfile using RomanPerekhrest's solution; then pipe results to
# an awk script to handle the 'search'

sort -k6,6 -t "|" ${dbfile} | awk -F"|" -v dateA="${dateA}" -v dateB="${dateB}" '$6>=dateA && $6<=dateB'
  • -v date[AB]="${date[AB]}"：将我们的bash变量传递给awk脚本;为简单起见，我们将保持相同的名称
  • -F "|"：为awk
    • 定义输入字段分隔符
  • $6>=dateA && $6<=dateB：仅打印其中field6位于（包括）我们的搜索日期
    • 之间的行

脚本的一些示例运行：

# no search dates provided (ie, use defaults; display entire file (sorted))
$ search.sh -f file.dat
