[/CODE]It's required so many \\\\\\\\\\\..., to reflect "\\"
That's because you're using double-quotes, where the shell handles escaping itself and needs two to tell it to ignore it. Try single single-quotes, where escaping doesn't happen in the shell:
And you can single-quote just part of an expression too, the way you've been doing with double quotes.
I just remembered another trick: IFS=$'\n' This will cause the shell to split only on newlines when expanding variables -- spaces in directory names won't bother it at all. IFS is a special variable telling it how to expand variables and how to split when using read. This is the 'clear text processing mechanism' you wanted

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 file name 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.
