Hi!

I'm trying to learn shell scripting and have runned into problems with functions.

Since you have to read all functions into memory before they are used it would be nice to be able to place all your functions in an functions.sh file and start the main script by running the function.sh script i.e. read all functions into memory.

Is this possible?

I have tried to place the functions in a script:

#!/bin/sh -vx

s_echo_hello()
{
echo hello
}


And then read it and tried to run the s_echo_hej in another script:

#!/bin/sh -vx

/tmp/common.sh

s_echo_hello


Here are the result:

#!/bin/sh -vx

/tmp/common.sh
+ /tmp/common.sh
#!/bin/sh -vx

s_echo_hej()
{
echo hej
}

s_echo_hej
+ s_echo_hej
./testi.sh: s_echo_hej: not found


Is this possible? And in that case, what am I doing wrong?


TIA

Hi again!

I just figured it out from http://steve-parker.org/sh/functions.shtml#libraries

You have to put a . before you execute the script with your functions.

I have at this time no clue what that . means. Any one?

It means 'source' the script into the current shell (as opposed to 'execute'). In some older shells you might actually have to use the word 'source' rather than the '.'.
