./script.sh Permission?

[narkie]

If you execute a shell script ie: ./script.sh and you
either:
a) Do not have permission to execute the script or

b) Do not have permission to execute commands inside the script

- Will it return an error message on the lines of "Can't execute....<blah>" or will it not return anything?

This script is running on a Solaris 9 system but I am happy to hear about what happens on all distro's.

Well, let's test it, shall we? I shall execute the following script as a regular user:

#!/bin/bash

./other_command

I do not have permission to execute "./other_command". Now let's see what happens:

alex@danu ~/test/bash $ ls -l no_perm 
-rw-r--r-- 1 alex users 29 Oct 19 00:18 no_perm
alex@danu ~/test/bash $ ./no_perm
bash: ./no_perm: Permission denied
alex@danu ~/test/bash $ chmod +x no_perm
alex@danu ~/test/bash $ ls -l no_perm 
-rwxr-xr-x 1 alex users 29 Oct 19 00:18 no_perm
alex@danu ~/test/bash $ ./no_perm 
./no_perm: line 3: ./other_command: Permission denied

Does this match what you expected?

[narkie]

Hmmm, not quite. I am getting ZERO output. I was thinking it was a permission's thing and I can't *get* the permissions at this stage either.

[Cabhan]

What do you mean you can't get the permissions? "ls -l" will show you the permissions.

Also, perhaps you can show us exactly what you're trying to do?

Zero output where? You need to redirect errors somewhere. You could also include this in your script.

example:

echo "hello" >> file_I_do_not_have_permission_to_write_to 2>/root/error.log

[narkie]

I just could not get access to an account with MORE permissions. ie: root level access. Anyway, the issue has been solved - although I can not give details as the script was just replaced with a known working version
- so there was just an issue with the script.

(>'ing it to an output did nothing at all, there was something seriously wrong with this script.)
