how i can execute more than one command at the same time ? (OS = sun solaris)
Glad to see you're willing to learn shell as I suggested earlier in another question. :-)
To put command in background and let it execute there:
To switch back to that process (if only one background process started):
To list all backgrounded processes:
If you just want to run a command, then another, and then another ....
The above example would proceed to the next command only if the previous command succeeded without errors. If you don't mind if the previous command succeeded or not, you can do
Anyway, all this is the kind of basics I shouldn't be explaining to you; go and read a tutorial to get started! Just Google for bash tutorials, if your shell is bash. You seem to be using Solaris, so your shell might as well be csh, in that case google for csh tutorials. They are similar to each other, but some differences do apply for example in environment variable stuff.
You're not trying to execute two commands at once, but rather, you wish to run a second command on the ouput of the first. SvenW has mentioned the -exec argument to find already, but another way is to use xargs, which allows you to use the output of a piped command as an argument to another command.
Let's say that you'd like to find every directory named foo, and see permissions on any files within that directory:
find / -type d -name 'foo' -print0 | xargs -0 ls -la
(See the man pages for find and xargs for use of -print0 and -0 if needed.)
Please explain what you want to do, because there are so many ways to do this.
Read any Linux/Unix beginners guides, this will be explained in great detail.
Also, this is not a beginners forum to learn the fundamentals. The type of questions you ask is better suited on the sister site superuser.com.
