Bash printf文字逐字字符串 [英] Bash printf literal verbatim string

问题描述

为使代码具有可移植性，我尝试使用printf而不是echo.但是然后

To make my code portable, I try to use printf rather than echo. But then

printf "-dogs-cats"

返回错误.当前情况下的解决方法是:

returns an error. A workaround in the present case is:

printf "-";printf "dogs-cats"

但是是否有通用的可移植命令(或带有printf的选项)将任意字符串打印为文字/普通字，而不是尝试将字符串解释为格式?

But is there a general, portable command (or an option with printf) that will print an arbitrary string as a literal/verbatim, not try to interpret the string as a format?

我在 BSD Unix(在Mac上)中工作，但是我的目标是编写代码也可以在其他Unix版本中使用.

I work in BSD Unix (on a Mac), but my objective is code that would work in other Unix flavors as well.

推荐答案

使用格式规范:

printf '%s' "-dogs-cats"
