Behavior of alias (bash script)?

Hi

I just install sun-jre on the box but I have little problem with it a little bit...

I has this in my .bashrc (I don't have root access so I install in /home folder and use alias)

#.bashrc
alias sunjava=/home/preecha/local/jre1.6.0_12/bin/java

This "sunjava" ran fine when I call from bash prompt but when I used another bash script calling it.

#!/bin/sh
#cytoscape.sh
sunjava -Dswing.aatext=true -Xss5M -Xmx512M -jar cytoscape.jar cytoscape.CyMain -p plugins "$@"

When I run .cytoscape.sh, the error occur.

./cytoscape.sh: line 9: sunjava: command not found

(but I can call this line without problem in bash prompt...)

Am I doing it wrong or missing something ?. Any suggestion would be really appreciate.

from man bash:

Aliases  are not expanded when the shell is not interactive, unless the
expand_aliases shell option is set using shopt (see the description  of
shopt under SHELL BUILTIN COMMANDS below).

I see. Thanks for replying.

there's also the info file which should be a bit easier to understand..(pinfo gives you info with colors if you care)

Re: Behavior of alias (bash script)?

just stash this in your .bashrc and you'll be fine. No need for that alias after this

PATH=${PATH}:/home/preecha/local/jre1.6.0_12/bin/

You could also put the path to your local java at the start to give yours preference over another java implementation installed on the box somewhere...

well thanks for that, But admin already has alias the "java"  to other command for some... who knows reason, so I'm a bit worrying if there'll be a conflict.
