10
20

50
Now I want to store those values into an array. How can be done this ?? (3 Replies)
Passing a array to a function, a basic feature in modern language, seems to be only possible in KSH. Not in BASH. Depite all my efforts I couldn't come to a solution. See the following examples:
It works perfectly in KSH:
#!/usr/bin/ksh
function print_array {
# assign array by indirect... (3 Replies)
Hi there,
I am trying to call a shell script from a Perl script. here is the code:
@args = ("sh", "someshellprg.sh", "a file handler", "an array");
system(@args) == 0
or die "system @args failed: $?";
in the shell program, I examine if the arguments exits using:
if

Hi,
I'm trying to write a function that reassigns an array to
another local array but the method used in reassigning
the array reformats the contents of the array which is
what I am trying to prevent.
The method used to load a file into an array works as
expected and the entire array is... (4 Replies)
Hi,
Is there an easy way to simulate following Perl code in Bash.
if ( grep {$my_value eq $_} @ARGV ){
print "Do Something\n";
} else {
die "Invalid value";
} (0 Replies)
Good grief so this should be easy. Passing an array as an argument to a function. Here is the sample code:
#/bin/bash
function foo {
local p1=${1}
local p2=(${2})
local p3=${3}
echo p1 is $p1
echo p2 is $p2
echo p3 is $p3
}
d1=data1
d2=data2

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.
