Is it possible to call a function from another script?

Thanks

Sort of.

# file1
foo()
{
    echo "foo was called"
}

#file2  
# source file1
. file1
# call the any function in file1
foo

Lets say I have two scripts A and B.

Script A is using a function in B

So I use . scriptB to get access to all functions.

This works fine if I run scriptA in directory that scriptB is in, but it does not seem to work if I run it in another directory?

5

create an absolute path. assume scriptB live in /home/chrisj

.  /home/chrisj/scriptB
6

Source scriptB using its full pathname.

. /path/to/scriptB

Thanks stating full path works fine
