Permission settings determine who can view and alter files on the computer. You change permission settings at the bottom of the Info window for a file, folder, or disk in the Finder. For example, you can change permission settings for a folder so that other users who log in to your Mac, or connect to it for file sharing, can view but not change files in a folder.

I want to write the Ubuntu analogue of a 'batch file' (a shell script). But I don't know how to use Eliah Kagan
chmod +x filename command to make it so that the script can be run. Nor do I know where to use it.

3 Answerschmod +x on a file (your script) only means, that you'll make it executable. Right click on your script and chose Properties ->Permissions ->Allow executing file as program, leaves you with the exact same result as the command in terminal.
If a file you want to change permissions on is located within the systems directory you may need to be
root , like so: (be careful, while using sudo command)
Also it is not clear, what exactly you want to archive here. Please edit your question and give some more detail on the actual problem!
You can also refer to this question, for more information: chmod u+x' versus 'chmod +x
Type
man chmod in a terminal window (Ctrl+Alt+T) and you'll get the following output:

First, your script must declare which interpreter to use. You do this in the first line of the file. If it's a shell script, it should be
#!/bin/sh or #!/bin/bash .
So here's a script that writes your username: echo-whoami.sh
#!/bin/shecho $(whoami)
To make it executable, use Jo-Erlend SchinstadJo-Erlend Schinstad
chmod +x echo-whoami.sh . Then you can run it using ./echo-whoami.sh .

A batch file and a shell script are two terms meaning effectively the same under Linux. The term script is far more often used, though.
The most simple shell script file just contains commands as you'd type them on the command line (that is, the Bash command interpreter). In theory you can even replace the interpreter with any language you like (and have an interpreter for). To be more explicit, it's suggested you start your first line with
#!/bin/sh (if you wan't maximum portability with legacy systems)
or
#!/bin/bash (if you want some extra features, you probably don't care about today)
After this line enter your commands, one on each line. There are lots of extra constructs beyond the scope of this questions, see
man bash or http://www.tldp.org/LDP/Bash-Beginners-Guide/Bash-Beginners-Guide.pdf (for Beginners) or http://www.tldp.org/LDP/abs/abs-guide.pdf (for more advanced questions).
To actually run your script, there are two requirements: First, the interpreter process needs to read the file, and second it checks if it is marked as executable. For convenience reasons it's also useful to be able to write to your script (so you can make changes or fixes should need be).
Assuming further that you want team members and other also to be able to run (and see) your script, but that you don't want them to manipulate it, the combination of

are usually sensible values of your file permissions. You can type the single actions concatenated, separated with a comma.
While this 'action language' is very fascinating (note the difference of the
+ and the = operator which result in different outcomes depending of the permission setting before you changed them), they are tedious to type.

As all of the actions create bit masks that are applied internally, you can type the bitmasks (see
man chmod for details) also directly.
For a shellscript chmod 755 myscript.sh makes most sense in at least 95% of all cases.
