Bash help
 

Hey there,

I'm new here and currently taking Bash Programming in college. I'm having a little problem right now with my code

i'm trying to have my program output the date/time whenever a user inputs the word "time" when my program prompts them to enter something

so far this is what the code looks like and I'm getting an integer expression expected


what am I forgetting?

-eq is a numeric comparison.

You want either == (or = when used in an expression), also suggest space after the closing " on "time".

Run down the bash manpage to "Conditional Expressions"

that worked, thanks! I'll be back for more help soon, probably

question: with if statements, if you have an if inside an if, do you need a fi at the end of the inner if statement

example:

yes.

Ok,

so more problems.

Here's my code:
When I enter "Directory" as my input, it tells me where I am at in my assignment. So the the output for me looks like this:
but there is more. after that it shows:
so im getting the correct output, but im getting an error message for my last if that I have. the statement bolded is the one with the error message

And the question is?

doesn't
need a closing "]"?, so
?

2 of the 3 braces need spaces before the closing right bracket.
time" ] and who" ] NOT
time"] or who"]

And those are to make the code work.

thanks for the help and info druuna!

on the who command, how do you get each user to appear on their own line so its not all mashed up?

You don't need to use echo for any of those commands, as that's what they'll do anyway. Just run the command, eg:
Same goes for date and pwd. You use the back ticks or $() when you want to execute something and pass the output into something else, such as a variable for parsing later on. Passing it into echo is rather pointless, as that's what the command is going to do anyway (plus echo will jumble up the line ends).

You may also want to start indenting your if blocks, it makes larger codes infinitely easier to read.

added another elif statement, because my assignment seems to contain a lot of them. Anyways, all my scripts are working except for the last elif statement.

This is the error I get when I execute the script using the "trigger" work if you will.

Thats the error, section of code it goes to

so, whats wrong with the script? I even tried changing echo Something to just `exit` to see if it would work, and it doesn't

You can't mix double and single quotes. A set of either has their own behavioural purpose (in short: one does allow expanding (""), the other doesn't ('').

That was my bad on typing here. My script has "". Still have same error

Please post the complete script, or at least the complete if-then-elif-fi part that doesn't work. Also post the exact error it throws.
