You could source the script with the function in it, perhaps that is what you need.
Does that do the sort of thing you need? You may also see the shortcut of . instead of source but it;'s a little less clear and more difficult to search for. You would end up with a line like . ./my_function_script.sh
Either way, the script being sourced is executed in the current shell so the declared functions remain available. You have to be careful that you really want to run it, so most people have a block on functions only in what they source in.
I hope that this helps,
Robin

Hi,
If I declare a function inside another function, it overwrites any previously declared function with the same name. This is NOT what I want.
Example:
#!/bin/bash
_test() { echo test; }
_myf() {
# I'm using the same name as the other function.
_test() { echo local test; }... (8 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 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.
