/sbin/sh in HP-UX is the true bourne shell, it is different of /usr/bin/sh (Posix compliant shell) in the way it works and is normally used only by root, therefore it is not a good idea to change root's default shell by anything else (you can always call your preferred shell later...). I have seen engineers doomed after changing their root shell in /etc/passwd after having (not so) serious issues with servers not rebooting properly and so in single user (ah bad luck, /usr isnt mounted...). see:
I'm puzzled by this one. I hope you can explain it to me.

I'm trying to call shell scripts from Java for DB operations. Using a very simple test, for some reason, one line of (ALTER TABLE) in the shell simply won't be executed while the exit value from the call is "0" (valid exit). When I run the script directly in Unix, it gets executed perfectly fine!!... (4 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.
