システム日付の取得。。。(BAT編)

BATでは、環境変数を利用します。
 %DATE%
 %TIME%

これだけでは場合によって足らない時があります。
システム日付を「YYYYMMDDhhmmss」で取得したい時は、文字列の抽出と文字の置換が必要になります。

抽出の場合は、こちらです。
 ~~
 ある変数の先頭(文字列の左端)からm番目の文字からn文字だけを取り出すには、
 「%V:~m,n%」とする(mは0から始まる)。
 ~~

置換の場合は、こちらです。
 ~~
 「%V:s1=s2%」の書式を使う。s1をs2に置換する。
 ~~

という事で、結果を書いてしまうと、

①YYYYMMDDで取得する場合は、
 > echo %date:~0,4%%date:~5,2%%date:~8,2%

②hhmmssで取得する場合は、
 > set time2=%time: =0%
 > echo %time2:~0,2%%time2:~3,2%%time2:~6,2%

①と②を文字列連結する事で、「YYYYMMDDhhmmss」形式で取得する事が可能になります。
