Using "Find" Command in tandem with "if" "and" statements

Question

I need to search and find sub-directories that contain a certain file, however if they contain this certain file + this other file, I do not want them to be listed.

The statement looks something like this:

1. Find the directories that contain the file "password.old"
2. If the directory contains "password.old" and "webvirtual" don't list them
3. If the directory ONLY contains "password.old" and does not contain "webvirtual" then output directory path to > OLD.TXT file

This is what I have thus far, is this totally wrong? It seems to be working correctly, but I'm fairly new to bash scripting and just wanted to make sure I'm not missing something... or maybe there's a better way to handle this?

#!/bin/sh
if FILE=$(find ./ -path OLD/ -prune -o -name "password.old") && FILE=$(find ./ -path OLD/ -prune -o -name "webvirtual*")
then
printf %"s\n" $FILE > Not_Old_Ones.txt
fi
if FILE=$(find ./ -path OLD/ -prune -o -name "password.old") && FILE=$(find ./ -path OLD/ -prune -o ! -name "webvirtual*")
then
printf %"s\n" $FILE > Old_Ones.txt
fi

Answer 1

I'd do:

find . -path ./OLD -prune -o -name password.old \
  ! -execdir [ -e webvirtual ] \; -printf '%h\n'

-execdir is found in GNU find (since 4.2.12 (2005)), sfind and most BSDs (where it comes from). -printf is GNU-specific. You can replace it with -execdir pwd \; for other find implementations.

If -execdir is not available:

find . -path ./OLD -prune -o -name password.old -exec sh -c '
  for file do
    dir=${file%/*}
    [ -e "$dir/webvirtual" ] || printf "%s\n" "$dir"
  done' sh {} +

The above would be POSIX. On Solaris 10 and older, be sure to use the standard sh in /usr/xpg4/bin, not the one in /bin.

Answer 2

Slightly lengthy , but working solution, which should work for cases where -execdir is not available:

$ tree
.
├── dir_one
│   ├── password.old
│   └── webvirtual
└── dir_two
    └── password.old
$ find . -iname "*password.old" -exec dirname "{}" \; 2>/dev/null | while IFS= read -r directory; do
> [ -e "$directory"/webvirtual ] && continue || echo "$directory"
> done
./dir_two

Thus , all you need to do now, it add > OLD.txt at the end of the done statement to redirect output to file

In case the dirname command is not available, you can use the following script with directory as argument.

#!/bin/sh

find "$1" -type f -iname "*password.old"  -printf "%h\n" |
while IFS= read -r directory;
do
    [ -e "$directory"/webvirtual ] && continue || echo "$directory"
done

For example:

$ ./find_missing_webvirtual.sh ./TESTDIR/                                                                                
./TESTDIR/dir_two
