Hello!
Thank You all for the answers.
The best solution for now is: test.sh:
Code:
#!/bin/sh
my_args="1 2 3 '4 5' 6"
echo "Count of arguments when using my_args:"
echo "./arguments_count.sh $my_args" > ./my_args.sh #put whole command into a file
sh ./my_args.sh #run the file
echo "Count of arguments when using direct string:"
echo "./arguments_count.sh 1 2 3 '4 5' 6" > ./my_string.sh #put whole command into a file
sh ./my_string.sh #run the file
Hi,
how can I join given arguments (not starting from the first one) to form one string, each argument separated by a space. For example, out of 5 given arguments, I'll like to start joining from the 3rd to the last. In python there exists something like ' '.join(sys.argv) and it starts joining... (5 Replies)
Hello, I was wondering if it were possible to call arguments passed to a script using a variable.
For example:
sh script.sh yes no good bad
x=$#
while
do
echo (last argument, then second last etc until first argument)
let x=($x-1)
done
should print out
bad
good

The following bash script does not work because the java/groovy code always thinks there are four arguments even if there are only 1 or 2. As you can see from my hideous backslashes, I am using cygwin bash on windows.

Let's say I want to print the arguments $4 till $#, how can I do this?
$# contains the number of arguments

Hi guys,

Maybe I havn't read deep enough

Hi
The following code works when reading the arguments from the command line but fails when I try to read from a string. So this works

Hi. I have a piece of code that reads and parses command line options. I'd like to alter it slightly to read from a string (that's set elsewhere in the script) rather than directly from the command line (arg). Can somebody show me how to do this? Many thanks.
My code is as follows:

escape
escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
