Dear monks
I am running a perl script
Depends upon the shell I have to add some feature to my script.
If my login shell is csh from the command line I can change to korn shell by giving 'ksh'. same way I can change to any shell I want ( 'bash','csh','sh').
From the command line if I execute echo $0, I will be able to find the shell name. How can I find this inside a script whithout using `echo $0`. I think there is no use of this command inside a perl script.
My code would be similar like this
$shell_name = find_the_shell
if ( $shell_name eq 'bash' ) {
# Blah .. Blahhh
}
elsif ( $shell_name eq 'ksh' ) {
# Blah .. Blahhh
}
elsif ( $shell_name eq 'csh' ) {
# Blah .. Blahhh
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>

<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
