Im having trouble calling a function

kdx1980 · 08-09-2011, 01:58 PM

Ive made a function and I cant seem to call it. it will run when I use it as a script, as soon as I make it a function glass()
{dls;ajgfl;dsajg;sl
gfdo;s'gkjfd'}
then I tried to put it into a script called run_glass
glass().

I get an error on line 4 doesnt recognize end of file. Basically I just put it into the file run_glass to see if it would run and it wouldnt. Do i need to put something before or after the function designation to get it to call and run properly? Hopefully this makes sense to someone. Thank you for reading

Hello,

Can you post the actual code of your script for us? The gibberish text you typed in doesn't help one bit man... Not trying to be a d*ck either, but without seeing code, how can we help you troubleshoot?

Cheers,

Josh

LOL no offense taken, Hey I just want to help you help me. Here is the code all I want to do is be able to call this function into another script that only contains this function merely to prove the function can be called and works
glass()
{
echo "enter in a number: "
read a
echo "enter in another number: "
read b
echo "the number $a to the power of $b is"
expr ="$(( $a ** $b )) "
}

Ahh ok.... You can use the source() call within your script to include functions from another script:

Code:

#!/bin/bash
source script_containing_function
glass argument

Hope this helps!

Cheers,

Josh

It's not a system call, just a bash builtin command.

The kernel has no concept of a shell, and they aren't integrated with each other.

Oh I know, I was just showing to use source like a function. Like I said in the past, I sometimes have a hard time explaining things :/

Function calls in bash don't use parentheses. Or are you talking about creating functions?

I used the parenthesis to let the OP that source was the command to use that would be used in importing a function from a different script. I didn't intend at all to mislead the OP......

I was talking about creating a function once you create it How do you add it to a script. Like for instance I want to run the function glass (that i created) in a script called run_glass. Where the only contents of the script run_glass is the glass function. how would I make that run? the script is above.

So the file "run_glass" contains the function "glass"? If so:

Code:

source run_glass

# now you can call the "glass" function here
