ksh: Need to read variables into variables

ksh: Need to read variables into variables

Post by Andree Fonteno » Thu, 14 Mar 1996 04:00:00



Inside a utility shell I have the statement:

  read TPL_LOC?" > " # get template path from user

I want to enter

 > $TPL_HOME/admin

where $TPL_HOME is a standard system variable and have $TPL_LOC
interpreted the same way it is on my command line.

The line

  TPL_LOC="$TPL_HOME/admin"

works, but I do not have the luxury of being able to hard code this. The
users of the utility need to enter their own pathnames.

Anyone have any ideas?

Try using the "eval" statement e.g.

read TPL_LOC?" > " # get template path from user
eval ls $TPL_LOC

1. Using a variable in a variable name in KSH

Group,

  I want to be able to use a variable name in another variable name.
 So for a simple file like:
 file: Prod
        Devl
        Test
        User

  Then I want.

   for n in `<file`
     do
            $n_Mail=`grep $n some_file` ## To get a list of names...
    done

     echo  "Mail var is $n_Mail : (and contents..??) "

    Output being.

     Prod_Mail :  joe jim etc
     Devl_Mail  : fred sally ...
     Test_Mail  :  etc
     User_Mail  :  etc

     So how can I assign the variable using the $n variable and view
the name  of the variable asn well as the contents..

  Any help greatly appreciated.
