Allowing export to take numbers as variables

[phil128]

Hello. I'm playing around with some shell scripting and I've got a directory call CS005 and I'm trying to write a script to I can locate to the directory really quick and easy.

export CS005DIR=/home/stud/0/043234/CS005

Now I get this error

CS005DIR=/home/stud/0/043234/CS005 No such file or directory.

This is because I've got numerical values within my variable.

Is there a way to allow numbers for variable names?
Thanks

It shouldn't be a problem, try to enclose the path in quotes

try this yourself:

CS005DIR="/home/stud/0/043234/CS005" ; echo $CS005DIR

bash should echo your path

Now that seems to work. I've also tried have a value like 2CS005DIR which doesn't work due to it starts with a number (2). Is there a way to allow this?

Thanks

You can use a little trick to make bash accept your variable name, start it with an underscore:

_2CS005DIR="/your/path" ; echo $_2CS005DIR

that should work.
