讀書筆記之101個腳本之No.8

這是第8/101個腳本

There are as many ways to solve this quirky echo problem as there are pages in this book. One of my favorites is very succinct:

You may prefer to avoid the overhead incurred when calling the awk command, however, and if you have a user-level command called printf you can use it instead:

But what if you don't have printf and you don't want to call awk? Then use the tr command:

This method of simply chopping out the carriage return with tr is a simple and efficient solution that should be quite portable.

這個腳本很簡單，就是可以用3種不同的函數（方法）來實作，輸出後不換行。
