UNIX for Dummies Questions & Answers

How could you put the output of two commands into one file using a single command? For example put the output of a grep command and a sort command into one file together.

Here is another rough explanation of what I am trying to do;

output of
$ grep pattern file1
plus output of
$ sort file 2
merged together in a new file called file 3?
I want to do all this in a single command. Is it possible?

I think it can done like

$ grep pattern file | sort file2 > file 3

Thanks but it didn't work. It just did wrote the part after the pipe into the file. Here is another example of what I am trying to do;
put a directory listing and the date together into 1 file using a single command.

Sorry...Even me new to UNIX commands...

I think for your second query the answer could be ...

$ ls -l > file.txt

this will put the file and directory names as well the access permissions and the timestamps into the output file.

something like this,

Code:

( grep start file; sort file ) > outfile

Thanks kumasaravana_s, what you say is correct but is not quite what I was after. Thanks for trying to help me. I wanted to for example show the output of the command date at the top of the file, followed by the the output of the command ls in the same file.

Yes matrixmadhan, that is it. Thanks a lot.
