Sorry if it is somewhere in the forum, I've checked for an hour or so with my google friend and can't figure this one out. Not counting the 2 hours I spent yelling at it.
Welcome to BASH + AIX
In short, I have a list of physical volumes (hdiskX), I want to create a variable hdisk1_size (for example with hdisk1) IF it does not already exists. If it exists, I just want to echo it; only if my $ARG="-all"
I know some part of it works since:
I have no idea what is wrong. I've tried wc the amount of letters within the variable, it acts weirdly when put inside the if but works well from the prompt:
So far I have tried:
It always says it's not empty even if not initialized
Note that the above will always be at least 1 (?):
I've tried a bunch of stuff ... I thought my logic might just be wrong but I can't figure another way of doing it.
Try read instead of eval. It can do the same job -- setting dynamic variable names -- with less doublethink. You can feed it the output of a shell command inside a here-document.
Note that the ending EOF must be at the beginning of the line, not indented.
You can also convert a variable containing a variable name into that varibable's contents with ${!VARNAME}, if you're using BASH or new enough KSH.
