sh

Hi out there,

I try to start several programs (compiled with g77) in batch mode. It works, if I start each binary file manually, but with sh i receive the message "no such file or directory", which I don't understand.

So, in a directory there are three programs, named

~⁄Desktop/Programme/Magnetik/program1
~⁄Desktop/Programme/Magnetik/program2
~⁄Desktop/Programme/Magnetik/program3

and this is the sh script:

~⁄Desktop/Programme/Magnetik/program1
read -p "Press enter if ready" nothing
~/Users/meinmacbookpro/Desktop⁄Programme⁄Magnetik⁄program2
~/Users/meinmacbookpro/Desktop⁄Programme⁄Magnetik⁄program3

The output of this script is:

magnetik.sh: line 1: ~⁄Desktop/Programme/Magnetik/program1: No such file or directory
Press enter if ready

But, if I start the first line manually:

~/Desktop/Programme/Magnetik/program1
File ois.xyz created

if works.

Why? Where is the error?

Thanks a lot for any small hint
Harry

Have you tried the full path in the script without the ~

yes, and again with no success.

But now, I have changed the line:

⁄Desktop/Programme/Magnetik

to

cd /Desktop
cd Programme
cd Magnetik

and then it works.

But if I change that line to:

cd /Desktop
cd Programme/Magnetik

I again receive the error message "no such file or directory".

I don't understand why...

Should the path be /home/Desktop ?

when I change to /home/Desktop, I get:

MacBook-Pro:gis meinmacbookpro$ sh magnetik.sh
magnetik.sh: line 1: cd: /home/Desktop/Programme/Magnetik: No such file or directory

So whats the full path then?

~⁄Desktop/Programme/Magnetik/

Or

~/Users/meinmacbookpro/Desktop⁄Programme⁄Magnetik⁄

Cd into the correct directory and type pwd (on the cli not in a shell script)

Are you using the right character encoding for the script file?

~/Desktop/Programme/Magnetik and

/Users/meinmacbookpro/Desktop/Programme/Magnetik respecitvely

How do you start magnetik.sh on the command line? You can use the to get the full path:

Code:

sh -x magnetik.sh

How about adding this on your script?

Code:

#!/usr/bin/sh

Not on a Mac. There it is in /bin, not /usr/bin. But I think even between Linux distribution the location varies, as on openSUSE it’s in /bin too.

But sure, running the script on its own is feasible. Then it needs to be set to executable too:

Code:

chmod +x Magnetik.sh
