It was not creating the alias that required me to run the script. When I double click on my alias, the script opens in Text Editor instead of running in Terminal. Unlike a windows shortcut or Linux launcher, the alias doesn't have a property to let you specify the program you want to open the file in. In order to get the script to run in Terminal, I had to do the steps I described to define "open with" for the script file (not the alias file). This is the procedure where I had to actually run the script in order to specify the "open with" program. Once I had done that, I could double click on the script (or on the alias) and it would run in Terminal. I actually don't know if this now applies to all files on the system with the .sh extension, or just the one script file. The alias works in any location where it's located. I believe this is just a symbolic link like ln.

After having set the "open with" value for the script file, when I double click on the alias file, a terminal window opens, the script runs, and finishes, but I get the [Process completed] message and the Terminal sits there in a non-functional state without the window closing.

This is what I want, I just don't know why the Terminal window closes when the script is finished on your system and stays open on mine. I have run this script on both windows and linux for a long time and I have never seen that before.

The fact that you have to take an intermediate step to specify what is to be used to run your script tells me that something is wrong. I'm guessing that you skipped part of the 1st step I mentioned in post #5. Please show us the output from the commands:

Code:

ls -l script
head script

where script is the name of the file containing your shell script.

If the mode of script doesn't allow you to execute it OR if the first line of script isn't #!/path/to/interpreter, then script is not an executable shell script file.

The link Finder is creating for me is not a hard link as would be created by ln nor a soft link as would be created by ln -s; it is a binary executable file that directly invokes terminal to run script or to run /path/to/interpreter /path/to/script.

NAME

       script - Makes a transcript of terminal session

SYNOPSIS

       script [-a] [file]

       The script command makes a transcript of everything printed on your terminal.

OPTIONS

       Appends the transcript to file rather than writing it to file.

OPERANDS

       The name of an output file that will contain the transcript of the session.  If this parameter is omitted, the file typescript is written.

DESCRIPTION

       The transcript is written to file, or appended to file if the -a option is given.  If no file name is given, the transcript is saved in the
       file typescript.

       The script ends when the forked shell exits.

       This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create	an
       example of a working session this way).

       If you specify the -a option and the file does not exist, it is created.

       If you do not specify the -a option and the file exists, it is replaced.

RESTRICTIONS

       The  script command requires a streams based terminal.  In single user mode, streams may not be enabled.  Under these circumstances, script
       will exit with no action.  If you are the superuser and need to run this command in single user mode, use the  following  special  instruc-
       tions.

   Enabling Streams
       If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams.  This command is avail-
       able to the superuser only.
