排序數據庫/殼牌

Question

我給它以這種格式

10027|Chen|Ning|female|1982-12-08|2010-02-22T17:59:59.221+0000|1.2.9.86|Firefox

（注意在T在第6列）結構化數據庫

我的任務是輸出數據庫的行的日期從給定的dateA到另一個給定的dateB。

到目前爲止，我試圖通過第6列按-M排序我的文件，特別是sort -k 6M -t "|" "file.dat"或sort -k6 -M -t "|"和其他試驗。

但沒有任何反應。

我需要分揀這樣就可以與awk

EDIT 例如指定的起始和結束日期， 從這個

Answer 1

最終，在這項任務中我沒有看到任何特別的東西 - 只需簡單的排序：

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

輸出：

Answer 2

添加了一對額外的數據線進行搜索的例子有點容易看到：

我將定義一個bash腳本[search.sh]具有以下輸入參數：

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 

實際的腳本：

$ 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]}"：通過我們的bash的變量到awk腳本;爲了簡單起見，我們會保持相同的名稱
• -F "|"：定義AWK
輸入分隔符
• $6>=dateA && $6<=dateB：只打印線，其中字段6之間（含）我們的搜索日期

的一些樣品運行腳本：

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