I have a utilitarian shell script full of goodies and wish to bring them to the bash environment. I used the command source before as analogous to import or include in other languages.
printer.sh
#!/bin/bash
printAwesome () {
echo "Awesome!"
}
printMoo () {
echo "Moo!"
}
I think it is only running the command source printer.sh on terminal. Is it really? Do we have any other procedure to follow?
In python, we have environments which we activate and deactivate.
If I understand correctly what it is you are trying to achieve, then loading your file with source is not enough. If you wish to use printer.sh as a module, you need to export each function's name that should be available outside your script. So printer.sh should look like this:
#!/bin/bash
printAwesome () {
echo "Awesome!"
}
printMoo () {
echo "Moo!"
}
export -f printAwesome
export -f printMoo
And then you can write something like this in myscript.sh:
#!/bin/bash
source printer.sh
echo "Let's run these functions ..."
printAwesome
printMoo
echo "Hey, that works now!"
export the functions if you are just using them in the same shell that does the sourcing. There is also no need to keep the #!-line on the script that you source as this will just be treated as a comment.
.bashrc, which may work for some punctual cases. In this case now, I wish to import in another context, like a bash session.
export -f
export didn't work. Can you explain which case would require it?
printMooavailable as if you were usingfrom printer import printMooin Python?sourcebefore..." vs. "I think it is only running the commandsource printer.shon terminal." -- what or who is the "it" that is running something there in the second sentence? What do you mean with only running the command "on terminal"?
