I have a file that has about 3000 commands , listed one below the other. I would like to execute them all in one go. Is there a simpler way to do it - like a batch file processing, than executing one line at a time?
Simple:
sh scriptname
Now, you have some interesting options. You can log all the output and error to a file:
sh scriptname &> all-output.log
An important option is '-x' which will log each command as it is executed.
sh -x scriptname &> all-output.log
Another interesting option is "-e" which will abort on an error.
sh -e scriptname &> all-output.log
The text file needs to be chmod to executable to run it as suggested.
@otheus you have suggested the all the best possible solutions.
One thing to remember you should know what are the commands doing. example a telnet/ssh or ftp command will have your script (text file) to loose control over the script unless these exit. You need these special commands to be handled specially with 'expect' or with special pipes.
Also if you want them to run as batch not one line at a time. I am assuming you need next command to start along with previous command. Just add a '&' to command. This will run in background.
Do make sure you read up about background commands before going further. You could seriously damage the host if you have multiple commands running in background.
Paste the text file you want make it run as script. That could give more details on how to handle things.
3000 commands in a row could get messy without anyone knowing what is being run. As long as nothing in there violates any sort of NDA etc I'd definitely get a few sets of eyes to go over it in case there are any hidden surprises.
I'm also going to go ahead and say make sure you put comments in the file to describe whats happening etc etc.
