Hello,

I have some problems in using quotes:

I want to use the dialog command in a script so that the user can select some options.

This works fine

Code:

index=0

str=""

valarray_tag=(1 2 3)

valarray_desc=('This_is_option_1' 'This_is_option_2' 'This_is_option_3')



for item in ${valarray_tag[@]}; do

        str=$str$item" "${valarray_desc[$index]}" "

        index=$((index+1))

        done

str=${str%' '}

dialog --menu "Test" 0 0 30 $str 2>/tmp/$$.dialog

But if I have descriptions with spaces I get in trouble!

Code:

index=0

str=""

valarray_tag=(1 2 3)

valarray_desc=('This is option 1' 'This is option 2' 'This is option 3')



for item in ${valarray_tag[@]}; do

        str=$str$item" "${valarray_desc[$index]}" "

        index=$((index+1))

        done

str=${str%' '}

dialog --menu "Test" 0 0 30 $str 2>/tmp/$$.dialog

By directly typing I can quote the string but how is this done in my for loop? I have tried

Code:

str=$str$item" '"${valarray_desc[$index]}"' "

but then the ' get \' and this is not what I wanted!

Any ideas?

Thanks

Does that do what you want?

Code:

index=0

str=""

valarray_tag=(1 2 3)

valarray_desc=('This is option 1' 'This is option 2' 'This is option 3')



ori=$IFS

IFS='\n'

for item in ${valarray_tag[@]}; do

        str=$str$item" "${valarray_desc[$index]}" "

        index=$((index+1))

        done

IFS=$ori

str=${str%' '}

dialog --menu "Test" 0 0 30 $str 2>/tmp/$$.dialog

Cheers,
Tink

no!

I have already tried this. How can I add a ' to a string without getting \'?

Ok I have solved my problem in an other way! Since the shell insist on quoting special characters like ' I will use it to automatically quote the right parts. So I put all in a new array!

Code:

#! /bin/bash  -xv



index=0

valarray_tag=(1 2 3)

valarray_desc=('This is option 1' 'This is option 2' 'This is option 3')



for item in ${valarray_tag[@]}; do

        newArray[$((2*index))]=$item

        newArray[$((2*index + 1))]=${valarray_desc[$index]}

        index=$((index+1))

        done

dialog --menu "Test" 0 0 30 "${newArray[@]}" 2>/tmp/$$.dialog

It rests the question: Is there any possibility to prevent the shell from automatically quoting, escaping things???
