如何在Unix和Linux中通过单个命令传递多个命令

Question

I want the o/p as list of owner and their file names , file path and the file size. I am using two commands to get the o/p. Can anyone suggest me how to get the o/p in a single command .The commands I am using are:

ls -l | awk '{print $3, $4 }' > test.txt 

This gives me the list of owner and the directory.

And the 2nd one is:

find . -size +100k -print0 | xargs -0 ls -sd >tets2.txt

This gives me the file name and size of the file .

Answer 1

Sort of don't understand, do you mean pipe them both or do each commmand in same line. To do the later, you can do

ls -l | awk '{print $3, $4 }' > test.txt    ;   find . -size +100k -print0 | xargs -0 ls -sd >tets2.txt

Answer 2

The first command returns the owner and group, not the file name. It only works for the current directory. The second command works for subdirectories also, but only for huge files. Two unrelated commands are hard to glue together, but if your goal is to prevent calling stat two times for a file, you can modify the following Perl script to suit your needs:

use feature 'say';
while (my $file = glob '*') {
    my @stats = (stat $file)[4,5,7];
    say join "\t", $file,
                   (getpwuid $stats[0])[0],
                   (getgrgid $stats[1])[0],
                   $stats[2];
}
