For loop with two vars

Paul Sperry — Thu, 12 Jan 2012 21:00:37 GMT

I have 2 files

file 1

1999
2000

File 2

12457
12458

and 2 directories

ls -al tars_1999

drwxr-xr-x 2 15709 15709 101 Jul 7 2011 12457_1999

drwxr-xr-x 2 15709 15709 101 Jul 7 2011 12458_1999

ls -al tars_2000

drwxr-xr-x 2 15709 15709 101 Jul 8 2011 12457_2000
drwxr-xr-x 2 15709 15709 101 Jul 8 2011 12458_2000

I would like out put to be

file2 number, 1999 size, 2000 size

I have tried:

for x in `more file1`
        do
                for y in `more file2`
                do
                        du -sh tars_$x/$y_$x
                done
        done

but it dosen't pick up the $y

also tried

n=1999
for x in 'more file2'
do
du -sh tars_$n/$x_n/*
n=$(( $n + 1 ))
done

but the n never changes.

Of cource this is just a small sample of the data I have

any ideas..

TIA

The better way to do it is:

for x in $(< file1)
        do
                for y in $(< file2)
                do
                        du -sk tars_${x}/${y}_${x}
                done
        done

Also note that HP-UX does not have the '-h' option with 'du'. So 'du -sh' has been changed to 'du -sk' above.

Thanks that works great.

Is the any way to output the results to a file

other than ./scriptname > outputfile

I guess I am looking for something with in the script to create the output file

Thanks

You can always just redirect the output of the 'du' command.

'du -sk ...' >> outputfile

If you do that, just be sure to append (with the >>) so you don't overwrite the file everytime.

>You can always just redirect the output of the 'du' command. 'du -sk ...' >> outputfile

You can also redirect the whole loop:

for x in $(< file1); do
for y in $(< file2); do

du -kxs tars_${x}/${y}_${x}

done

done > outputfile
