I tried to write a small ksh script:

fDestExists (){
    cd /tmp
    read vANSWER?" >> Do you want to create a repository in pwd ? Type YES or NO"
        echo "    |----> $(fGetDatum) You typed: " $vANSWER         
        if [ "$vANSWER" = "YES" ]; then
                read vANSWER2?" >> Type your repository's name."
                mkdir -p $vANSWER2
                cd $vANSWER2
                echo "    |----> Logs will be coped in pwd."        
        elif [ "$vANSWER" = "NO" ]; then
            echo "    |----> Logs will be coped in pwd."        
            echo "    |----> You typed a wrong answer; exiting."        
            exit 1
    pwd #return

Several questions here.

  1. How can I use pwd's value in my echo?

  2. To return value, I read it was feasible using echo [yourValue] at last line. Then where you call the function, I guess I can use : $?. So how can I do the same behaviour with pwd?

1: you can directly use the PWD variable, eg:

echo "    |----> Logs will be coped in $PWD."

2: $? is used to retrieve the last command return value which is numerical. There is no way to pass a string here, the return value should be 0 meaning success or something different meaning some failure. Use return 0 or return -1 if you want to get that information. As you are modifying the script current directory, it will be available as $PWD in the caller side anyway.

  • Can I ask you one more question ? Is there any conventions about how writting script in KSH ? Like doing systematically "unset" to variables I use ? Or always using typeset to define new variables. Commented Nov 18, 2013 at 10:06
