ls to show only directory/filename and size

Question

First of all, this is not a duplicate of this: Linux ls to show only filename date and size

Because I want to print actual directory name additionally.

I was always using this command:

ls -l | awk '{print $5, $9}'

to get the each file size and name. But now, I need to print the file directory additionally.

Is that possible?

Answer 1

You mean like this, just prepending the current directory to each filename?

ls -l | awk -v PWD=$PWD '{printf("%s %s/%s\n", $5, PWD, $9); }'

(the -v just imports the $PWD shell variable into the awk script).

Or something else?

OK, apparently what you want is

$ cd /some/path/to/somewhere
$ <insert command here>
somewhere/file1 size1
somewhere/file2 size2
...

Is that correct?

If so, the change you need is this:

ls -l | awk -v PWD=$(basename $PWD) '{printf("%s/%s %s\n", PWD, $9, $5); }'

If you have an older shell, the $() may not work, in which case try:

ls -l | awk -v PWD=`basename $PWD` '{printf("%s/%s %s\n", PWD, $9, $5); }'

instead. I don't have immediate access to any shell that doesn't support $(), but I can't think where else your Illegal variable name error would come from, when this works for me.

If it still doesn't work, please describe your platform, shell, version of awk etc. in your question - the comment thread is getting pretty long and I'm running out of guesses :-)

Answer 2

If you want to include the directory part of the file name in the ls output, include it on the command line.

ls -l "$PWD" | awk '{print $5, $9}'

If you want to print a relative path, arrange to call ls from the right directory so as to print the relative path you want, e.g.

dir=$(dirname "$PWD")
cd .. && ls -l -- "$dir" | …

Do be aware of the pitfalls of parsing the output of ls: if a user name or a group name or a file name contains whitespace, that snippet spews out nonsense.

A reliable, but non-portable, way of listing file attributes in a custom format is stat.

stat -f '%8z %R' -- *
stat -f '%8x %n' -- "$dir"/*

A slower but more flexible way of producing this output is to iterate over the files inside the shell.

for x in *; do
  printf '%8d %s\n' "$(wc -c <"$x")" "whatever/you/want/$x"
done

Answer 3

This is borrowed from what Useless has suggested above:

/bin/ls -l | awk -v PWD=$(basename $PWD) '{ if ($1 != "total") {printf("%s/%s %s\n", PWD, $8, $5);} }'

/bin/ls -l | awk -v CUR_DIR=$(basename $(pwd)) '{ if ($1 != "total") {printf("%s/%s %s\n", CUR_DIR, $8, $5);} }'

This, however, filters the total xyz line. Note that output of ls might differ on different distributions. Mine shows file name in the 8th column (whereas Useless shows it as 9th column). Sample output is shown below:

ds/binary_search.py 1660
ds/growth.png 28262
ds/growth.py 1147
ds/heap.py 1277
ds/postfix.py 969
ds/prim.py 39
ds/queue.py 1188
ds/quicksort.py 2535
ds/QuickSortWeiss.class 2821
ds/QuickSortWeiss.java 3500
ds/sin-cos.py 401
ds/sin-cos-two.png 28509
ds/sorting.py 4997

One last point: it might be helpful to provide the exact location of ls. Otherwise, in case if ls is aliased to something else, the output might again vary.

Update:

The above command doesn't seem to work on all systems, am not sure why. However, this one should work, I hope.

/bin/ls -l | awk  '{ if ($1 != "total") {printf("%s/%s %s\n", $(basename $(pwd)), $8, $5);} }' | awk '{ print $8, $9 }'
