You can't do it quite the way you were trying to do it because you can't currently create arrays of nameref variables
Quote:
The underlying problem is: arrays in bash (and ksh88 as well) are ONE-dimensional. Therefore, you can create a variable holding a one-dimensional array, but you can't put other array variables as elements into this array.
I had a feeling I'd get that kind of answer but was still hoping for a syntax fix
Quote:
This would rely on "${selector}" to be evaluated first and only then the resulting "${xfoo}" to be evaluated again. But, as i said, this is not the case and therefore this will fail.
Yes that's exactly what I wanted, evaluate "${selector}" first then "${xfoo}" :S
Because my script is pretty much done and I've never written ksh before, I guess I'll just stick to adding array names manually as I go. At least this implementation works in bash.
Thanks!

Hey All,
I'm trying to clean up a variable using sed but It dosn't seem to work. I'm trying to find all the spaces and replace them with "\ " (a slash and a space). For Example "Hello World" should become "Hello\ World". But it does nothing. If I put it directly into the command line it works... (3 Replies)

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a filename containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
