海绵和三通之间的区别 [英] Differences between sponge and tee

问题描述

在做一些工作时，我发现此海绵"命令的功能与"tee"相同，但是找不到何时使用哪种更好.

While doing some work, I found this "sponge" command that does the same as "tee", but could not find when it is better to use one or the other.

有人可以解释吗?

推荐答案

没有人吸收 stderr ；仅 stdout . ' tee '在 stdout 和文件上写入 stdin . "海绵"仅将 stdin 写入文件；没有错误，没有输出. (即:与" tee "不同，"海绵"不会在 stdout 上书写). 此外，

No one of them soak up stderr; only stdout. 'tee' writes stdin on stdout and files. 'sponge' writes stdin only on a file; without errors, no output. (i.e: Unlike 'tee', 'sponge' doesn't write on stdout). Besides,

海绵吸收所有输入，然后再打开输出文件"

"sponge soaks up all its input before opening the output file"

(摘自手册)

它们之间的区别极为相关:" tee "读取一个字节"，然后写入该字节"； "海绵"等待接收所有输入，然后将其写入.

This difference between them is extremely relevant: 'tee' "reads a byte", and "writes that byte"; 'sponge' waits to receive all the input, and then, writes it.
