[ubuntu] Will I ever get to grips with linux? Running a script .sh

[reggiep]

Ok thanks to webman and others have my Zimbra installation up and running. I can run a number of commands to backup the aforementioned zimbra but I can't save those commands as a script .sh and then run that?

 

I have saved my script as zbackup.sh

 

I then tried runnig it but no go.

I have a read round and find I need to chmod it.

 

I tried chmod it like so

 

$ chmod ugo+rx zbackup.sh

 

but I still get this error when I type "zbackup.sh" at the prompt

 

-bash: zbackup.sh: command not found

 

Am I missing an abvious, to linux, step?

 

Thanks

Couple of things. Is the file in the same directory you are trying to run the command from? ie is it in your /home/user and your console at that location too?

 

Next, is the file secretly named 'zbackup.sh.txt' or something?

[webman]

It's a security feature. As you have already applied the execute permission (chmod +x) you can run the script like this:

 

./zbackup.sh

 

If it doesn't have the execute permission, you need to run it as a parameter:

sh zbackup.sh

[reggiep]

the sh zbackup.sh worked, well it started the script anyway!

 

Thanks

[localzuk]

Doh! How didn't I spot that?!

[reggiep]

Can I come back in with my next problem now?

 

I have my script, well webmans with some different paths, and I can execute it by typing "sh zbackup.sh" at the prompt BUT when I do execute it I get a response as follows...

 

 

: command not found

: command not found

I'm not sure how I have managed to cock up since it works fine if I paste the text straight in to the prompt!

[webman]

Ah. Instead of sh, try bash. My mistake

[powdarrmonkey]

For background, the first line of the script (#!/bin/bash) tells you which interpreter should be used to run it.

 

It's in that weird format so that the shell can also tell, so if you just call ./zbackup.sh instead of bash zbackup.sh, things work as expected. Being able to do this is more convenient, since you don't have to dig into the script to find out what interpreter should be using it.

 

By convention, if you have that first line in a script (it's called a 'shebang' or 'hashbang') and the file has the execute bit on, you usually don't put a suffix on the script name. So yours would just be called zbackup. This makes it obvious that the file has a shebang and can be executed directly.

[reggiep]

with either sh or bash I still get the error I mentioned before?

 

On a separate note thanks to everyone who has helped me with this so far. I would be nowhere without your help.

I'm enjoying this long and winding road which is linux.

[webman]

Have you tried changing to the directory the script is in and running it using the ./ method? As long as it has the +x attribute it should work as powdarrmonkey said.

[reggiep]

Yep in in the directory that the zbackup.sh is in. If I type ./zbackup.sh I get a different error!

 

-bash: ./zbackup.sh: /bin/bash^M: bad interpreter: No such file or directory

 

 

Does that mean anything?

[powdarrmonkey]

Yes. Say "which bash" to check where bash is living, and set your shebang to there instead.

[Geoff]

The file is in DOS CR/LF (the ^M is the CR character) rather than UNIX LF style. Whatever you used to transfer the file from your windows PC mangled it. I use WinSCP here and it will detect and do the right thing™.

 

Use 'dos2unix ' to fix it.

 

You might want to try editing/creating scripts directly on your Linux machine in future. I do it via a SSH session using 'nano'. If you use Putty as your SSH client you can right click to mass paste text into the editor.

[Gatt]

Damn you Geoff - was jus about to say that the ^M didn't look right..

[powdarrmonkey]

Ah, good spot. I wondered, then forgot.

I am using Putty and I pasted directly from a notepad file!

 

I am learning quickly here.

 

thanks

Sorry to but in but has anyone here tried importing all their users from a CC3 network (windows Server 2003) into zimbra?

 

I'm trying to use a command from the zimbra site called ldap2zm.pl but i cant for the life of me get it working!

 

Got almost everything else up and running.

 

Any ideas?

[powdarrmonkey]

Sorry to but in but

 

Don't. Open a new thread, please.

[reggiep]

Use 'dos2unix ' to fix it.

.

 

dos2unix did the trick.

 

Thanks again for everybodies help. I believe I now have a fully functional and backed up zimbra.

Are you trying to import mail as well ?

 

We use zimbra auth'ed against the CC3 AD, I knocked up an quick php script to create a csv of all the users on CC3 AD then did a bulk create on zimbra.

 

This was a couple of years ago though.

@budgester

 

Do you have any more info about how you did this?

 

At the moment i am just exporting users from sims in a csv and then importing

[reggiep]

Sorry, to get back on topic!

I can now run the script by typing ./zbackup.sh but It doesn't run in crontab.

 

I have ..

00 23 * * Mon-Fri /usr/local/bin/backupscripts/zbackup.sh

 

Do I need to change this somehow so it has the ./ in there?

 

Could I change to the correct directory with the crontab and then execute weith ./ in front?

 

Thanks (yet again)
