Although it may not be required, but was fun as a problem to crack. I faced this when writing my own provider script for Tip (a very recommended small app for Mac).
Yet another reason I'm happy to have server be with Mac Stadium now. myscript.sh Line 1 - Is whats referred to as the shebang. It is text after a shebang expression in a script that is run by zsh, while eventually running the rest of the code. In an ironic twist, when I used to have a shell account on a Linux box, changing my zsh scripts to start with #!/usr/bin/env zsh failed because that version of Linux had env at /bin/env instead. (The only thing you have to be careful about is that if you use any features that have been added to /usr/local/bin/zsh but are not in /bin/zsh then you should specify /usr/local/bin/zsh.) Portability Is Hard… So, while I expect most of my zsh scripts will be used by people who only have /bin/zsh, because I use env I can use /usr/local/bin/zsh too. As soon as FOO is found in one of those folders, it will be used.
Looks like Mac OS X requires interpreter to be binary, not another script.
I can run the script if I just run it as bash test.sh. Then env will look at /usr/local/bin first, and then /usr/bin and so on. Shebang pointing to script (also having shebang) is effectively ignored. /test: invalid option name I ran cat -v test.sh to check if there are carriage returns or anything, but that doesn't seem to be the case. PATH=/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin Answer (1 of 2): The Shebang (or Hash Bang) is a standard method across Unix inspried O/Ses to inform the O/S which executable to use to run the script - this includes Linux and MacOs. Well, you could change all of your scripts to use #!/usr/local/bin/perl but then if you are on a Mac which does not have /usr/local/bin/perl installed, it will fail.īy using #!/usr/bin/env FOO you are telling the script, “Use whichever version of FOO that you find first in the PATH." The reason to do this is that someone might be using a different shell but you want to make sure they use the right one, otherwise the script will fail.īUT what if you installed a newer version of perl at /usr/local/bin/perl and want to use that one instead of the one at /usr/bin/perl? Normally you will see something like this: Then you make the compiled AppleScript executable ( chmod +x shebang.scpt ). Then you type the AppleScript itself, finishing by pressing Control-D on your keyboard. The only exception to that is if it is the first line, and is #! followed by the program you want to use as an interpreter to the shell script. On macs, the default installation (activated by /bin/bash ) is an older version which causes the script to fail with a syntax error whenever &> is used. First you compile the AppleScript into the resource fork of shebang.scpt ( /usr/bin/osacompile -o shebang.scpt ). Normally, any line in a shell script that begins with a # is assumed to be a comment.
