bash script with case statement

Question

I have a file called Namebook, with following data inside:

$ cat Namebook
Kamala Hasan  123
Rajini kanth  345
Vijay         567
Ajith kumar   908
$

Then I have a bash script to add a new name in the file Namebook, called add_name.sh

$ cat add_name.sh 
#!/bin/bash

echo "$1   $2"  >> Namebook
$

Next I have a script to look someone from this Namebook, called look_up.sh

$ cat look_up.sh
#!/bin/bash

grep "$1" Namebook
$

Then again I have a script to remove someone from this Namebook, called remove.sh

$ cat remove.sh
#!/bin/bash

grep -v "$1" Namebook > tmp/Namebook    
mv tmp/Namebook Namebook
$

These scripts add, lookup and remove users from the Namebook file.

Based on the combination of these three script, I created a single script, all_action.sh, to perform all said actions

$cat all_action.sh
#!/bin/bash

echo 'Select the option
      1. Lookup some one from the Namebook
      2. Add name to Namebook
      3. Remove name from the Namebook

Select the options range of (1-3): \c '

read choice

case "$choice"
in
   1) "Enter the name to lookup: \c"
       read name
       look_up "$name" ;;

   2) "Enter the name to be add: \c"
       read name
      "Enter the number to be add: \c"
       read number
       add_name "$name" "$number" ;;

   3)  "Enter the name to be remove: \c"     
        read name
        remove "$name ;;
esac

My question: when I execute the program all_action.sh, it throws an error

For example: I am going to run ./all_action.sh

Select the option
          1. Lookup some one from the Namebook
          2. Add name to Namebook
          3. Remove name from the Namebook

     Select the options range of (1-3): \c
1
Enter name to be lookup

./all_action.sh: line no : look_up: command not found

Could you please any one help on this ?

Put the full path to your bash executables. i.e /somepath/look_up — Raman Sailopal

Hi Raman, All these scripts are available in my current directory, all the files are having executable permission also. for example /home/user/scripts/loo_up.sh — user6420577

AS the answer suggests, if the files are in the same directory, you will still need to reference them with e.g. ./look_up — Raman Sailopal

The commands: look_up, add_name, remove are not found. Put the complete path in your script and specify the Interpreter:

sh /home/myuser/myscript.sh

or with relative path:

sh ./myscript.sh

The interpreter should not need to be specified; the files should contain a shebang that does that themselves.

Hi apensiv, I added full path name inside the script all_action.sh For example: full_path/look_up.sh "$name" ;; like this i was added other paths to add_name and remove also. Now its working good.
