Hello everybody,

I have the next problem, in my direcory Films I have a lot of uncompressed MOV files from my camera. Like this:

...
But I have many files, hundreds.

I wrote this command to convert them:

Could you please to help to cover this simple command in a script. Just to start a script and it will convert all the *.MOV files in my current directory.
Thank you very much in advence.

This will convert all *.MOV files in the current directory to an avi file of the same name if it doesn't exist yet. (if won't overwrite)

Thank you very much, I did this script convert.sh


but I got this error:





What does it mean ? Do you know ?

The same error I got with another script like this, it's strange for me, the same error in two different scripts. What I did wrong? Can't understand

The variable substitution part ${var//from/to} is very bash specific.
You're starting your script with 'sh' and I think your 'sh' is not bash. (test this by doing a ls -l /bin/sh)
Since the first line of the scripts contain #!/bin/bash I suggest starting them like ./script.sh

I will come at home, and I will try. May be you are right. Because I use Terminator and not a standard terminal.

Yep! You were completely right! Thanks a lot for the help!
I have this :

What is it dash, I don't know
But your script work well like this:

PS: I understand that /bin/sh -> dash it's symbol link, but the same result I have on my another computer. Strange.

dash is just another shell like bash, ksh, csh or any of the other shells that have been created over the years. It is also the default shell of Ubuntu for some time now. (since version 6.10). This is done to improve boot-up speed, because according to Ubuntu, dash has a smaller footprint and therefor load time than bash. Unfortunately it is not 100% bash compliant, which you have just seen.

As long as you stick with a bash sha-bang at the beginning of your scripts and run them as you do now, you'll be fine.

Yeahh, right, I use Ubuntu Linux.
Thanx a lot for inforamtion and for help. Now I will know. A little bit sorry, that dash is not 100% bash compliant with standart bash.
The problem is 100% closed.
