Hi there !
I would assume at this stage that your user accounts use /bin/bash as the
default
shell.
Here is what you do :
1) Place your script in a directory where you can find it easily. For
example , let's call your script
'/usr/scripts/myscript'. This is the script that runs your menu system.
2) Change to the user "abc" home directory. ( cd ~abc )
3) Edit the '.bash_profile' file.
4) Ensure that '/usr/scripts/myscript' has the appropriate permissions ,
based on your execution method :
a) Using the 'dot' command : '. /usr/scripts/myscript'
This will mean that the current shell will execute the script
without invoking a sub-shell
process. For this , your script will need only read permission.
b) Using explicit execution : '/bin/bash /usr/scripts/myscript'
This will invoke a subshell to execute your script. Your script
must have read
permission for user "abc" to execute in this fashion
c) Execute script using implicit execution : '/usr/scripts/myscript'
You simply place the name of your script with it's full path name
in your file. No
preceding 'dot' or 'bash'. This requires that your script has BOTH
READ and EXECUTE
permissions for the user "abc" ( This method will also invoke a
subshell )
4) Place a command within the '.bash_profile' to execute
'/usr/scripts/myscript' , according to 4a)-c)
stated above. For security reasons , you should always fully qualify
your commands and scripts
with their absolute pathnames.
5) At the bottom of the '.bash_profile' file , AFTER the line where you
execute '/usr/scripts/myscript' ,
insert an 'exit 0' command. When the user "abc" logs on , the
'/usr/scripts/myscript' will
execute , and then "abc" will be immediately logged out of the system ,
and will not have access to
a shell prompt.
