ls -laLR /home/tools > all_site1.txt

I need the state of all folders and files in subfolders of /home/tools. With this command I put all in this file. What I need now is a solution how to parse from this file all_sites1.txt only lines where owner of dir or owner of the file is root.

I tried this:

awk '/root/{print $0}' all_sites1.txt

But I get all places where root occurs. I need only those entries where owner is root and what file and/or dir is to be printed.

If you are looking to save the state of folders/files, getfacl is a much better command to use. You could do the following:

getfacl -LR /home/tools >all_site1.txt

One thing to note though is that the behaviour of the -L option is different from that of ls. It only follows symlinks to directories and not files.

You could print the output of files owned by root like this (provided none of the paths contain newlines):

awk '$2=="file:" && file_line=$0 {}
  $2=="owner:" && $3=="root" { print substr(file_line,9) }' \
  all_sites1.txt

Creating a pipeline from awk and cut is a bit strange, isn't it? –  Hauke Laging Feb 22 at 16:42
    
@Hauke Not really, awk has no support for selecting multiple arbitrary fields. Originally I had cut -d ' ' -f 3-, which replaces a complex awk line. cut -b isn't scuppered by leading whitespace in the filename though. But now that you mention it, I can just use substr in awk. So in this case, yes I guess it is strange. –  Graeme Feb 22 at 17:03

Another solution:

shopt -s nullglob
stat -c%n:%U:%G * .*[!.]* ..?* | awk -F: '{if( $2=="root" || $3=="root")print $1}'

This will work on files in the current directory only.

For reasonable file and directory names (not starting with space, no newlines) this works:

ls -laLR 2>/dev/null | 
    awk 'NF>8 && ($3 == "root" || $4 == "root") '\
    '{$1=""; $2=""; $3=""; $4=""; $5=""; $6=""; $7=""; $8=""; '\
    'sub("^ *",""); print;}'

As usual find is the better solution:

find . -user root -or -group root 2>/dev/null
