No, that will not work. To make things simple I would suggest to write the bash script in a separate file and call it from C program by passing the required arguments:
This way it will be easy to maintain.
that was my first option. but the whole goal here was to conceal the bash code. so i figure if i can embed it into C, i'll be able to hide the code. but if C is calling the script, the script will be open for everyone to read.
as i was typing this, something else occurred to me. i'm thinking, i can encode the script using a password. tell C to decode the script using the password i put in the C code. and then C can call the script after script has been decoded.

catch
catch(n) Tcl Built-In Commands catch(n)
__________________________________________________________________________________________________________________________________________________NAME
catch - Evaluate script and trap exceptional returns
SYNOPSIS
catch script ?varName?
_________________________________________________________________DESCRIPTION
The catch command may be used to prevent errors from aborting command interpretation. Catch calls the Tcl interpreter recursively to exe-
cute script, and always returns without raising an error, regardless of any errors that might occur while executing script.
If script raises an error, catch will return a non-zero integer value corresponding to one of the exceptional return codes (see tcl.h for
the definitions of code values). If the varName argument is given, then the variable it names is set to the error message from interpret-
ing script.
If script does not raise an error, catch will return 0 (TCL_OK) and set the variable to the value returned from script.
Note that catch catches all exceptions, including those generated by break and continue as well as errors. The only errors that are not
caught are syntax errors found when the script is compiled. This is because the catch command only catches errors during runtime. When
the catch statement is compiled, the script is compiled as well and any syntax errors will generate a Tcl error.
EXAMPLES
The catch command may be used in an if to branch based on the success of a script.
if { [catch {open $someFile w} fid] } {
puts stderr "Could not open $someFile for writing
$fid"
exit 1
}
The catch command will not catch compiled syntax errors. The first time proc foo is called, the body will be compiled and a Tcl error will
be generated.
proc foo {} {
catch {expr {1 +- }}
}
