less †

↑

may be a binary file. See it anyway? †

日本語ファイルをlessで開こうとすると出る場合がある。
stringsコマンドでASCII部分は見る事ができるので見てみる。
```
strings file
```

文字コードを変換してlessで表示 †

ターミナルがUTF-8で、ファイルがSJIS/EUC-JPの場合、文字化けする。

環境: CentOS 7
文字コード自動変換しつつ、色付き表示。ターミナルがUTF-8の場合: -w / SJIS: -s / EUC-JP: -e
```
sudo yum installl nkf -y 
export LESSOPEN='| src-hilite-lesspipe.sh %s | nkf -w'
```

環境変数「LESSCHARSET=ja_JP.eucjp」は「invalid charset name」でうまく動作しなかった

色が付かない
```
iconv -f EUCJP /path/to/file | less
```

lessキーボードショートカット †
