how to make permanent alias on nodes?

[yanyan]

I read through the content on how to make permanent alias on computer. I added alias in .bashrc file. But after log out then log in, it still could not remember that. What i should do? Is there anything else i could try? thanks a lot.

Well, that should work. Maybe you could post the exact alias command you put in ~/.bashrc.

Hi, in fact, i did that. In .bashrc file, i added following things:
alias rupme='echo `hostname -s` `uptime`'
alias rupall=rcom rupme

then saved it then logged out. But when i logged in again, it could not work.

Does the rupme alias at least work? If you typed it just like that (no typos), it looks correct.

The rupall alias will not work. First, you need to single-quote the two commands. Second, what is rcom? A command or another alias?

After logging in, type the alias command without arguments. It'll show you which aliases are currently in place for you.

[yanyan]

well, rcom is the command used for controlling nodes connected to main computer. I used single quote when writing alias command, but i did not write it correctly in posting news in this forum. Sorry for my mistake. But anyway, it could not work. It has no memory. There was once i asked my advisor who suggested that it could be related to my system. The nodes used system a little different from my main computer.

I should have asked this earlier, but what shell are you using? echo $SHELL

Doing an alias with the csh-based shells is a little different.

Also, could you post the results of the alias command and the exact contents of your ~/.bashrc file?

[yanyan]

I forgot to past the content after i used rupall alias on my main computer just now. It is like following:
bash: rupme: command not found
bash: rupme: command not found
bash: rupme: command not found


Could it help by any way?

Could it help by any way?

Sure - it demonstrates that there is no alias for 'rupme' and no command called that either.

Could you post your ~/.bashrc file?

[yanyan]

One thing i found is that, i could not use echo $shell on my main computer or nodes for it responded blank. The following is the content of .bashrc file:

# .bashrc

# User specific aliases and functions

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

# configuration file - MASTER NODE ONLY
# Environmental variables

CVS_RSH="ssh"
CVSREAD="read"
CVSROOT=":ext:zhangl@***.***.***.***:/home/cvs"

export CVS_RSH CVSREAD CVSROOT
export CUPS_SERVER=strada.***.***.***

alias uptodate='cvs status . | grep status | grep -v "Up-to-date"'

# Aliases for use on all machines.

alias ls='ls --color=tty -F'
alias dir='ls -al'
alias dirss='ls -alF | grep "/"'
alias new='ls -alFt | head'

alias strada='ssh -X strada'
alias rupme='echo `hostname -s` `uptime`'
alias rupall='rcom rupme'
alias cp='cp -i'
alias grep='grep -i'
alias mv='mv -i'
alias rm='rm -i'

I don't know if it can help.

[anomie]

It's strange, yanyan. The alias

alias rupme='echo `hostname -s` `uptime`'

is syntactically legit .

Let me ask a different question: Do the commands hostname -s and uptime work from the command line?

P.S. (bash, sh) env variables are generally upper case. You need to use echo $SHELL
