i have a shell script which calls another shell which in turn calls another shell script.
Main_shell_script.sh
shell_script_A.sh
shell_script_B.sh
in the above 3 scripts,
when i am assigning a different value to variable "FILENAME" in shell_script_B.sh script, its getting assigned properly and the value of the FILENAME is "sample.txt". but when the control is returned back to the main_shell_script.sh, the value in the variable FILENAME is blank. so after assigning the FILENAME to DST_FILENAME, DST_FILENAME contains nothing.
But according to the program since i am calling each shell script with a dot (.) in front, it should run in the same address space. so the variables declared in the main shell script should be visible to the other shell script and changing the value of the variable in any shell script should reflect in the other scripts also.
but, when i change the value of FILENAME in shell_script_B.sh, the changed value is not reflected in the main_shell_script.sh.
Can anyone tell where i am going wrong??

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.
