ポスト処理実行スクリプト¶
パラメータファイルからのコマンド実行¶
計算後に、 毎回、一定の決まったポスト処理 （グラフ生成など）をする場合、 パラメータファイルにポスト処理を記載し自動実行できると便利 ．
情報整理 の観点で◎ ( readme 不要 )
スクリプト化すれば入力ファイル選択により 自動実行可能 ( e.g. go__phits.py )
使い方¶
コマンドの記載¶
コメントラインとして、<postProcess>句を記載して、コマンドを記載する
# <postProcess> cp out.dat result.dat記号 "#" はコメントマーク．変更可能．
スクリプトの実行¶
command__postProcess.py スクリプトを呼ぶ．:
$ command__postProcess.py parameter.inp
or
$ command__postProcess.py parameter.inp -c --comment_mark $
etc.
引数¶
Argument |
Attribute |
Description |
|---|---|---|
inpFile |
第一引数 |
入力ファイル名 |
--comment_mark |
Optional |
コメント記号 ( Default: '#' ) |
--command/-c |
Optional |
設定すればコマンド表示のみ、実行なし |
コマンドの登録¶
他のコマンドと同様、以下の３つを設定
スクリプト先頭におまじない（shebang）を記載 ( e.g. "#!/usr/bin/env python3.10" )
パスの通ったところにおく ( e.g. /usr/local/bin/ )
実行権限付与 ( e.g. chmod +x /usr/local/bin/ )
コマンドライン実行可能に
$ command__postProcess.py replace_sample.conf --comment_mark $
