Перебрать файлы в каждом подкаталог и примените условие

The problem is this line in your ${COMPANYHOME_ROOT}/bashrc_company file:

export PROMPT_COMMAND='PS1=`echo "\u@\h$PS2"`'

The PROMPT_COMMAND variable defines a command that should be run before a prompt is shown. In your case, this has been set to setting PS1. So, each time a prompt is shown, your PS1 is being reset to the dwefault value.

I have no idea why anyone would want to do this, but it's simple enough to fix. Either delete that line from ${COMPANYHOME_ROOT}/bashrc_company or set PROMPT_COMMAND to something else in your ~/.bashrc:

PROMPT_COMMAND=""

Вы можете сделать что-то вроде этого:

dir=$1

subdirectories = $(find $dir -type d) # find only subdirectories in dir

for subdir in $subdirectories
do
   n_files=$(find $subdir -maxdepth 1 -type f | wc -l) # find ordinary files in subdir and get it quantity

   if [ $n_files -eq 4 ]
   then
      do_something_4
   fi

   if [ $n_files -eq 3 ]
   then
      do_something_3
   fi

   if [ $n_files -lt 3 ]
   then
      do_something_else
   fi
done

Предполагая, что подкаталоги расположены непосредственно в верхнем каталоге:

#!/bin/sh

topdir="$1"

for dir in "$topdir"/*/; do
    set -- "$dir"/*.ar

    if [ "$#" -eq 1 ] && [ ! -f "$1" ]; then
        # do things when no files were found
        # "$1" will be the pattern "$dir"/*.ar with * unexpanded
    elif [ "$#" -lt 3 ]; then
        # do things when less than 3 files were found
        # the filenames are in "$@"        
    elif [ "$#" -eq 3 ]; then
        # do things when 3 files were found
    elif [ "$#" -eq 4 ]; then
        # do things when 4 files were found
    else
        # do things when more than 4 files were found
    fi
done

Или, используяcase:

#!/bin/sh

topdir="$1"

for dir in "$topdir"/*/; do
    set -- "$dir"/*.ar

    if [ "$#" -eq 1 ] && [ ! -f "$1" ]; then
        # no files found
    fi

    case "$#" in
        [12])
            # less than 3 files found
            ;;
        3)
            # 3 files found
            ;;
        4)
            # 4 files found
            ;;
        *)
            # more than 4 files found
    esac
done

Ветви кода, которым требуется имя файла, используют "$@"для ссылки на все имена файлов в подкаталоге или "$1", "$2"и т. д. для ссылки на отдельные файлы. Имена файлов будут путями, включая каталог $topdirв начале.
