Thank you Alister. Thanks everyone.

I have 4 quick questions:

Question 1.

According to Wikipedia /bin/sh means Bourne shell . Is that Right?

Shebang (Unix) - Wikipedia, the free encyclopedia


Question2.
So, in Solaris 10, RHEL Version5, version 6, AIX version 6, 7 , if i forget to add shebang to a script , will the script be executed using Bourne shell ?


Question3.
Regarding CarloM's post on sourcing . /path/to/script.sh
I have used sourcing only to set environmental variables in the current shell. Can sourcing be used to execute shell scripts as well?



Question4.
I have noticed that some people execute shell scripts by putting sh at the beginning like

Code:
sh /path/to/myscript.sh

I always execute shell scripts without the sh at the beginning.

Code:
/path/to/script.sh

Which is recommended ?

The Shebang!

Hi, I always thought that #!/usr/bin/ksh means that the script would be executed in korn shell i.e. when we'll execute the script with this line as the very first line then the shell spawns a korn shell (in this case as we are using #!/usr/bin/ksh ) and the script gets executed. But I am... (7 Replies)

lr_environment

LR_ENVIRONMENT.IN(1)					  LogReport's Lire Documentation				      LR_ENVIRONMENT.IN(1)

NAME

       lr_environment - Export Lire configuration in shell script form

SYNOPSIS

       eval `lr_environment`

DESCRIPTION

       The lr_environment command is used to import the Lire configuration in Lire shell scripts.

       All of Lire configuration variables will be written in a format that can be evaled by the shell.

       Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.

       The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
