Hello All. I am a total linux n00b and am having trouble with scripts. I am taking a basic linux class and I have to write a script with input and output, and it must have branching (a loop or if statement).

In any case, I have decided to write a script (hopefully) that will ask the user what the base and height of their triangle is, and then my script will calculate the area for the user.

Writing the actual script will be fun and challenging for me, but to test out launching scripts I have been researching them online and found this website: http://tldp.org/HOWTO/Bash-Prog-Intr...O-2.html#ss2.1

In any case, I am using Ubuntu right now and went to: Applications -> Accessories -> Text Editor.

Then wrote:
#!/bin/bash
echo Hello World

I then clicked file -> save as... and the name of my file is "hello.sh". Under the "save in folder" option I chose the folder "Documents".

So then I click Applications -> Accessories -> Terminal and type "./hello.sh" and the next line says "bash: ./hello.sh: No such file or directory"

How do I launch a script in terminal/What am I doing wrong?!

Any help is GREATLY appreciated :-D

It sounds like your problem is that you aren't located in the Documents directory when you attempt to execute the script. You'll want to either change into that directory with the cd command, or specify the path when executing.

Example with cd:Example with path:Keep in mind that if you haven't set the executable bit on the file, it won't execute. You'll want to either use the graphical file browser and right-click the file (then select Properties, Permissions, etc.) to make it executable, or from the command line with something like:As an alternative to making it executable, you could specify that you want your shell to run it, like:

Hi -

The problem is that "Applications -> Accessories -> Terminal" defaults to your "home" directory, and "Applications -> Accessories -> Text Editor" probably defaults to some different directory (like the equivalent of "My Documents").

SUGGESTION:
1. In the command prompt, type <= This will tell you what your "home" directory is

2. In your text editor, do an explicit "File, Save As" to that directory.

3. From the command line, do or'Hope that helps .. PSM

Wow, Thank you SO much man, that worked. I am extremely appreciative of your help.

No problem, happy to help.

The simplest way to do this stuff is just to work in a terminal. It'll all become much clearer.
