#前面怎么设置能让它显示[用户@主机名 目录]
==>
修改PS1环境变量.
相对而言bash比较容易做到,man bash有详细的说明,只要设置PS1就可以了
\a an ASCII bell character (07)
\d the date in "Weekday Month Date" format (e.g.,
"Tue May 26")
\e an ASCII escape character (033)
\h the hostname up to the first `.'
\H the hostname
\n newline
\r carriage return
\s the name of the shell, the basename of $0 (the
portion following the final slash)
\t the current time in 24-hour HH:MM:SS format
\T the current time in 12-hour HH:MM:SS format
\@ the current time in 12-hour am/pm format
\u the username of the current user
\v the version of bash (e.g., 2.00)
\V the release of bash, version + patchlevel (e.g.,
2.00.0)
\w the current working directory
\W the basename of the current working directory
\! the history number of this command
\# the command number of this command
\$ if the effective UID is 0, a #, otherwise a $
\nnn the character corresponding to the octal number
\\ a backslash
\[ begin a sequence of non-printing characters, which
could be used to embed a terminal control sequence
into the prompt
\] end a sequence of non-printing characters
比如: \w显示目录,会随目录变化而变化
ksh要显示目录或时间就比较麻烦些,因为没bash这样的替换符号,你只能用pwd或date来设置,所以要利用其他一些技巧 |
