I think the answer might be execute permission. If a script has +x then you can execute just as you would execute a binary file. E.g.
Code:
user@linux: ls -l disk_space.sh
-rwxr-xr-x 1 user users 40 2009-07-21 12:49 disk_space.sh
user@linux:~> ./disk_space.sh
My script has a execute permission and I ran it like any binary file, same goes for perl scripts. But you also have to define the program which will interpret your scripts in the very first line. For Perl, it's usually, #!/usr/bin/perl or where your perl is installed. Else I'd have to use:
Code:
user@linux:sh disk_space.sh
or
user@linux:perl some_perl_script.pl
HTH,
Nitin
you are correct, the #! line tell the shell what to run the "script" under.

install_name_tool
INSTALL_NAME_TOOL(1) General Commands Manual INSTALL_NAME_TOOL(1)NAME
install_name_tool - change dynamic shared library install names
SYNOPSIS
install_name_tool [-change old new ] ... [-rpath old new ] ... [-add_rpath new ] ... [-delete_rpath new ] ... [-id name] file
DESCRIPTION
Install_name_tool changes the dynamic shared library install names and or adds, changes or deletes the rpaths recorded in a Mach-O binary.
For this tool to work when the install names or rpaths are larger the binary should be built with the ld(1)-headerpad_max_install_names
option.
-change old new
Changes the dependent shared library install name old to new in the specified Mach-O binary. More than one of these options can be
specified. If the Mach-O binary does not contain the old install name in a specified -change option the option is ignored.
-id name
Changes the shared library identification name of a dynamic shared library to name. If the Mach-O binary is not a dynamic shared
library and the -id option is specified it is ignored.
-rpath old new
Changes the rpath path name old to new in the specified Mach-O binary. More than one of these options can be specified. If the
Mach-O binary does not contain the old rpath path name in a specified -rpath it is an error.
-add_rpath new
Adds the rpath path name new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary
already contains the new rpath path name specified in -add_rpath it is an error.
-delete_rpath old
deletes the rpath path name old in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O
binary does not contains the old rpath path name specified in -delete_rpath it is an error.
