Define variables with UNIX script

oopps! I Meant "Define Variables within a UNIX Script"


What would be the best way to define a variable in a unix shell script so anyone who views this script doesn't know what value is assigned to that variable.


Code:
some other location...
a="/usr/lib/fileA"

Unix script...
sed s/input1/input2 <$a >newfileA

What are you trying to achieve ?
Are you trying to store a password because you want your script use this password to pass some other commands ?

Trying to access a file that I would not want any other user to know where this file resides. Hope I make sense.... Smilie Basically I created a unix script to manipulate data in a text file that I don't want any other user that would happen to view this script know where this file is on my server.

In that case why don't you use your environment then ? .[ceklp]* should not be readable to anyone else no? (Im thinking of custom variables in .profile or .kshrc and aliases...)

It is more a permission issue than a scripting issue then ... i think you should clearly identify what are you needs in terms of access granting and then set the relevant chmod chown chroot and sudo stuff to achieve those restrictions instead of adding new lines of code to handle such kind of things.

Gotcha! I was planning on changing the permissions to the unix script, just thought maybe I'd also have the location of this file defined as a variable in a private location. I'll try defining it in my .profile. Thanks guys!
