want to make multiple flags in script?

I want to make a multiple flags for my script. And didn't work like what I want it.

Code:

  #!/bin/bash



function wherecpy

{

    echo "Plaes write where the files are located: "

    read placefile

    cd $placefile

}



function funcpy

{

    wherecpy

    echo ""

    echo "Please choose the following:"

    echo ""

    echo "1. Interactive copy, answer yes or no (y/n) before doing the copy"

    echo "2. Make backups of existing destination files"

    echo "3. Preserve file attributes"

    echo "4. Do a recursively copy"

    echo "5. Back to main menu"

    echo ""

        echo -n "Enter Your Selection: "

        read selection

        echo ""

    case $selection in

        1) a="-i" ;;

        2) b="--backup" ;;

        3) c="--preserve=all" ;;

        4) d="-r" ;;

        0) return 0 ;;

    esac

    echo "Type the name of the file you wish to copy/backup: "

    read file

    echo "Type the name of the destination file/directory: "

    read dest

    cp $a $b $c $d "$file" "$dest"

    if [ $? == 0 ]; then

    echo "Success"

    else

    echo "failed."

    fi



}

I want it to work like that :

Quote:

Please type in the source file(s) to copy: File1 file2 file3
Please type in the destination: dir1
Copy successful.
Press any key to return to main menu.

thanks!

1. Bash interpretor will not run into your functions directly. As you have it right now, the interpretor bypasses your functions.
You have to invoke your function explicitely from the script. Add wherecpy at the end of your script.

2. As you have it right now, only one parameter will be added to 'cp' command.
You need something like this in funcpy function:

Code:

<here the user input>

flags=""

if [[ $selection = *1* ]]

then

    flag="$flag -i"

fi

if [[ $selection = *2* ]]

then

    flag="$flag --backup"

fi

if [[ $selection = *3* ]]

then

    flag="$flag --preserve=all"

fi

if [[ $selection = *4* ]]

then

    flag="$flag -r"

fi

if [[ $selection = *5* ]]

then

    return 0

fi

...

...

...

cp $flag "$file" "$dest"

I did it like this way

Code:

#!/bin/bash







flag1="." #variables that checks if the flag already exists

flag2="."

flag3="."

flag4="."

flags="" #variable that contains all variables



function funcpy

{

putin=

until        [ "$putin" = "0" ]; do

        echo ""

        echo "Please choose the following:"

        echo ""

        echo "1. Interactive copy, answer yes or no (y/n) before doing the copy"

        echo "2. Make backups of existing destination files"

        echo "3. Preserve file attributes"

        echo "4. Do a recursively copy"

        echo "5. Zero to flag"

        echo "6. Back to main menu"

        echo ""

        echo -n "Enter Your Selection: "

        read putin

        echo ""

        case $putin in

                1) if [ $flag1 == "." ]; then #checking if the flag is there, and then put it

                flag1="-" #to this

                flags="$flags -i"

                echo $flags

                fi

                ;;

                2) if [ $flag2 == "." ]; then

                flag2="-"

                flags="$flags --backup"

                echo $flags

                fi

                ;;

                3) if [ $flag3 == "." ]; then

                flag3="-"

                flags="$flags --preserve=all"

                echo $flags

                fi 

                ;;

                4) if [ $flag4 == "." ]; then

                flag4="-"

                flags="$flags --recursive"

                echo $flags

                fi

                ;;

                5) clear #to rest the flags (but not working :/ )

                flag1="."

                flag2="."

                flag3="."

                flag4="."

                flags""

                funcpy

                ;;

                6) show_menu ;;

                *)

                ;;

        esac

                

                echo "Please type in the source file to copy: "

                read filee

                echo "Please type in the destination: "

                read destinatioon

                cp $flags $filee $destinatioon

                if [ $? == 0 ]; then

                echo "Success"

                press_enter

                

                else

                echo "Failed"

                press_enter

                

                fi

                

done

}



function press_enter

{

        echo ""

        echo -n "Press (Enter) To Continue"

        read

        clear

}

Quote:

Please type in the source file to copy:
/home/user1/Music/doc1 /home/user1/Music/doc2
Please type in the destination:
/home/user1/Desktop/
Success

Press (Enter) to continue

And its work now :D

How I can make the flags rest ? I did one but didn't work.

what does "How I can make the flags rest ? I did one but didn't work.' this sentence mean?
Probably you missed a = here:

Code:

                5) clear #to rest the flags (but not working :/ )

                flag1="."

                flag2="."

                flag3="."

                flag4="."

                flags=""

                funcpy

                ;;
