Discussion between Zero Piraeus and Babbleshack

test is a bash builtin - called with no arguments, as in your example, it does nothing1. Your shell script is not called test but test.sh, so to run it you need to type: $ test.sh 1 Technically, it unsuccessfully does nothing (in other words, it returns a non-zero error code). If that means...

Babbleshack

when i run test.sh i get command not found error.
I am going to try renaming my script

I renamed my file to foo.sh made a link and i am getting a 'command not found' error

Zero Piraeus

@Babbleshack that probably means your ln -s ./test.sh /usr/bin failed ... do you see an entry for /usr/bin/test.sh if you type ls -l /usr/bin/te*?

@Babbleshack are you sure that you successfully made the link? What's in /usr/bin?

Babbleshack

yer its there i ran ls | grep testme in /usr/bin and it shows the link

Zero Piraeus

No ... use ls -l /usr/bin/te*. There's a reason I'm suggesting this.

Babbleshack

lrwxrwxrwx 1 root root 11 Aug 17 22:33 /usr/bin/testme.sh -> ./testme.sh

its there i ran that command from home dir

hi thanks for your help by the way

Okay, now think about it. From the point of view of /usr/bin/testme.sh, what does ./testme.sh actually mean?

No problem :-)

Babbleshack

well . mean current dir so it means look in current dir for testme

Zero Piraeus

. is the current directory. The current directory for /usr/bin/testme.sh is /usr/bin.

Babbleshack

i dont understand?

the script is found in my documents with a link to /usr/bin

Zero Piraeus

What you actually needed to do was something like ln -s /home/babbleshack/testme.sh /usr/bin (depending where the file is) - relative links like ./something are relative to the place where the link is, not relative to where you were when you typed the ln command.

Babbleshack

oooh i made the link using ln -s ./testme.sh /usr/bin
should i have instead put in the full path

Zero Piraeus

Bingo :-)

Babbleshack

haha thanks for that, an the time to think about the problem kudos for you

Zero Piraeus

No problem ... and sorry for taking you the long way round, but I noticed when I was learning this stuff that if someone forced me to think about it, I remembered it better.

Babbleshack

no i am glad, thats how i have been trying to learn things. i don't know how to give you merrit without putting the answer as correct.

Zero Piraeus

I'll edit the answer a bit so it's clearer to future readers.
