docker

dockerでシェルスクリプトを作るには、何かエディタがあるとよい。

エディタ

# apt install vim

編集

# vi py.sh

拡張子はsh(shell script)

実行権

# chmod +x py.sh

+x で実行権(eXecute)を付与する。

実行

./py.sh ch01

./をつけて、現在のディレクトリのファイルであることを指定。

例題

py.sh

#!/bin/bash
cd $1
for f in *.py 
  do 
    python $f.py
  done
cd ..

というファイルを作成

# ./py.sh ch01
(null): can't open file 'analyze_webstats.py.py': [Errno 2] No such file or directory
(null): can't open file 'gen_webstats.py.py': [Errno 2] No such file or directory
(null): can't open file 'performance_test.py.py': [Errno 2] No such file or directory

# ls ch01
analyze_webstats.py  data  gen_webstats.py  performance_test.py

おお、実行時の.pyが余分だった。

py.sh

#!/bin/bash
cd $1
for f in *.py
  do 
    python $f
  done
cd ..

実行しなおし。

し、し、しまった。python 2.7じゃないとダメだった。
