server variables in bash scripting
are they any server variables in bash/SSH scripting as is in PHP or Perl, for example in PHP:
$_SERVER['DOCUMENT_ROOT'] or $_SERVER['HTTP_HOST']

I'm trying to retrieve the absolute path of an .SH script I'm running





thank you

To answer the question, yes there are variables.

As and example...the absolute path to the current script would be:

ABS_PATH=$(cd $(dirname $0); pwd)

what about

Code:
echo $PWD

But that won't give the path of the script being executed unless the user is executing the script from the directory in which it resides, it will give the working directory of the parent.

As my other post but with echo, to display the value.

Code:
ABS_PATH=$(cd $(dirname $0); pwd)
echo ${ABS_PATH}
