awk + sum all numbers












4















We want to calculate the first numbers that we get from du



du -b /tmp/*

6       /tmp/216c6f99-6671-4865-b8bc-7205f5388752_resources

668669  /tmp/hadoop7887078727316788325.tmp

6       /tmp/hadoop-hdfs

42456   /tmp/hive

32786   /tmp/hsperfdata_hdfs

6       /tmp/hsperfdata_hive

32786   /tmp/hsperfdata_root

262244  /tmp/hsperfdata_yarn


so final sum will be



sum=6+668669+6+42456+32786+6+32786+262244





echo $sum


How we can do it by awk or perl one liners?






linux shell-script awk perl disk-usage

In AWK:



{ sum += $1 }

END { print sum }


So



du -b /tmp/* | awk '{ sum += $1 } END { print sum }'


Note that the result won’t be correct if the directories under /tmp have subdirectories themselves, because du produces running totals on directories and their children.



du -s will calculate the sum for you correctly (on all subdirectories and files in /tmp, including hidden ones):



du -sb /tmp


and du -c will calculate the sum of the listed directories, correctly too:



du -cb /tmp/*

    It is simple you can use:



     du -b /tmp/* | awk 'BEGIN{i=0} {i=i+$1} END{print i}'


    If you are not using wildcard, if you are using directory name like /tmp, then you need to avoid the last entry because output of du -b /tmp is like:



    size1 file1
    
size2 file2
    
size_total .


    So now you should avoid this last entry, so use:



    du -b /tmp | awk 'BEGIN{i=0} {if( $2 != "." ){i=i+$1}} END{print i}'


    However you can also use -s option, it will calculate the summary for you then you don't need to add the values, just print the last one, i.e.:



    du -s directory

    You can also produce a total sum of selected files with du -c. This works even if an argument of du is not a directory, what is not the case of du -s:



    $ du -sb file1 file2
    
17  file1
    
18  file2
    

    
$ du -cb file1 file2
    
17  file1
    
18  file2
    
35  total


    BTW, for interactive use I recommend adding -h option instead of -b or any other multiplier of block-size. This will print the size in human readable unit format.



    $ du -ch file1 file2
    
4.0K    file1
    
4.0K    file2
    
8.0K    total

                  You can also produce a total sum of selected files with du -c. This works even if an argument of du is not a directory, what is not the case of du -s:



                  $ du -sb file1 file2
                  
17  file1
                  
18  file2
                  

                  
$ du -cb file1 file2
                  
17  file1
                  
18  file2
                  
35  total


                  BTW, for interactive use I recommend adding -h option instead of -b or any other multiplier of block-size. This will print the size in human readable unit format.



                  $ du -ch file1 file2

Would the strong nuclear force cause attraction between a proton and an antineutron? Would such a nucleus be stable, or would the proton somehow annihilate the antineutron when close enough? nuclear-physics antimatter share | cite | improve this question asked yesterday
