问题
I want to disable the Unix shell prompt character ($, #, %) which usually we see in terminal. Is there any command or setting which can do this? I am using Solaris OS.
By shell prompt character I mean:
>$
>#
回答1:
You need to adjust your PS1 environment variable in your .profile file. I guess you could set it to "" to have it empty.
ex:
export PS1=""
EDIT: it can also be in your .bashrc file, or any other shell you are using.
回答2:
You can get fancy and put the host name in there. But basically you change the PS1 environment variable:
export PS1=hello
You can add this command in your ~/.bashrc file. Or other startup file, if you use another shell.
回答3:
I suggest first check the man pages for the shell (whatever is yours? echo $SHELL) under shell variables.
There are four types of prompt strings(PS) PS1, PS2, PS3, PS4, for your problem PS1 adjustment is sufficient.
To check the current settings: echo $PS1
To change: PS1="" for the current session, to make it permanent export it in your ~/.bashrc or ~/.profile.
To make it permanent for the user: export PS1="whatever special characters you want"
for more special characters and examples you can visit here "http://linuxconfig.org/bash-prompt-basics"
