Some shells allow access to script parameters using syntax as follows:
Code:
#!/bin/bash -
# @(#) s1 Demonstrate shell script parameter use.
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1)
echo
echo " Parameters beyond 9 explicit:"
echo " Parameter 10 is ${10}"
echo " Parameter 11 is ${11}"
echo
echo " Parameters with delayed evaluation using \"eval\":"
for ((j=1;j<=$#;j++))
do
eval echo " Parameter $j is \${$j}"
done
exit 0
Producing:
Code:
% ./s1 a b c d e f g h i j k
(Versions displayed with local utility "version")
Linux 2.6.11-x1
GNU bash 2.05b.0
Parameters beyond 9 explicit:
Parameter 10 is j
Parameter 11 is k
Parameters with delayed evaluation using "eval":
Parameter 1 is a
Parameter 2 is b
Parameter 3 is c
Parameter 4 is d
Parameter 5 is e
Parameter 6 is f
Parameter 7 is g
Parameter 8 is h
Parameter 9 is i
Parameter 10 is j
Parameter 11 is k
However, I think shift is usually the most useful construct ... cheers, drl
Hi All,
I need some help/ideas in coming up with a shell script.

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 filename 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.
