script to ask the user to select a number

family_guy · #1 (**permalink**) 03-11-2009

hi all,

I have 4 scripts which i would need to run
1. BP.sh
2.DB.sh
3.LK.sh
4.TB.sh

I would like write a script which would ask the user to select a number from 1-4 accordingly and run only that script for him/her

I succeeded till reading the user input but not sure how to run that specific file ( lets say if user puts 2, then i need to run ./DB.sh)

echo " Please enter any one of the following values and press Enter"
echo "1 for BP"
echo "2 for DB"
echo "3 for LK"
echo "4 for TB"
echo "Enter value:"
read mInputValue
if ( $minputvalue = 1)
then......

Thanks in advance...

If your shell supports the select construct:

Code:

PS3='choose a script: '

select s in *sh; do
  ./"$s"
  break
done

1) *sh
choose a script: bp
all_scrt[4]: ./: 0403-006 Execute permission denied.

bp is having 777 permissions to execute

Could you post the entire script? I'm wondering why the shell does not perform globbing on the *.
You should choose the number 1, 2 and so on:

Code:

% head *sh
==> BP.sh <==
echo $0

==> DB.sh <==
echo $0

==> LK.sh <==
echo $0

==> TB.sh <==
echo $0
% cat s
#! /bin/sh

PS3='choose a script: '

select s in *sh; do
  ./"$s"
  break
done

% ./s
1) BP.sh
2) DB.sh
3) LK.sh
4) TB.sh
choose a script: 1
./BP.sh

You could also change the code like this:

Code:

#! /bin/sh

PS3='choose a script: '

select s in *sh; do
  [ -e "$s" ] && ./"$s"
  break
done
