-n option with ECHO command in Linux
提问by Vaishali Modi
采纳答案by Vaishali Modi
man echo
man echo
-n Do not print the trailing newline character. This may also be achieved by appending `\c' to the end of the string, as is done
by iBCS2 compatible systems. Note that this option as well as the effect of `\c' are implementation-defined in IEEE Std
1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to
use printf(1) to suppress the newline character.
Many built-in commands to Linux have a manpage (e.g. man ls), which is a great way to look at the manual without having to search online.
Linux 的许多内置命令都有一个man页面（例如man ls），这是一种man无需在线搜索即可查看ual的好方法。
