Title: shell script question
Post by: Stryker on 22 June 2003, 10:47

In bash of course...

I would like to be able to do something like:

Code: [Select]

Can anyone help with making the above work properly?

In case you can't tell, I want to make a script that will tell me when I get online. As with ifup it doesn't say the dialing status.

Thanks

Code: [Select]

The bash if statement doesn't do conditional at all, the test builtin does. Bash creates an alias called '[' so you can do 'if [ "$x" = 2 ]; then' and make it look nice. The if statement actually just performs another statement, and if the statement returns 0 then it does the stuff between 'then' and 'fi'. And of course all executables and bash commands return status integers.

So you were close.
