用於讀取表格數據的命令行實用程序
我正在尋找一個命令行實用程序,它可以讓我快速調查大型數據集的結構。現在我正在使用:
head -n 2 dataset
但問題是輸出的寬度大於我的終端/螢幕的寬度。完美的是一個水平滾動文件的工具(按固定數量的列),就像我可以使用
Ctrl+f
/滾動瀏覽在 Vim 中打開的文件一樣Ctrl+b
。
我會推薦
less
您可以向任何方向瀏覽
less -S logfile
-S或**–chop-long-lines**
Causes lines longer than the screen width to be chopped rather than folded. That is, the portion of a long line that does not fit in the screen width is not shown. The default is to fold long lines; that is, display the remainder on the next line.
用於水平移動
ESC-)或RIGHTARROW
Scroll horizontally right N characters, default half the screen width (see the -# option). If a number N is specified, it becomes the default for future RIGHTARROW and LEFTARROW commands. While the text is scrolled, it acts as though the -S option (chop lines) were in effect.
ESC- **(**或向左箭頭
Scroll horizontally left N characters, default half the screen width (see the -# option). If a number N is specified, it becomes the default for future RIGHTARROW and LEFTARROW commands.
