Yes, if there were 8 files it would leave the oldest file intact. That's why the script makes the check before backing the ACLs up. In practice the script will use a directory where nothing else will be stored, and the first time the script is run there will be no backups. That's why I know beforehand that there won't be more than 7 files.

What's the advantage of using

cscope-indexer
cscope-indexer(1) General Commands Manual cscope-indexer(1)
NAME
cscope-indexer - Script to index files for cscope
SYNOPSIS
cscope-indexer [-v] [-f database_file] [-i list_file] [-l] [-r]
DESCRIPTION
This script generates a list of files to index (cscope.out), which is then (optionally) used to generate a cscope database. You can use
this script to just build a list of files, or it can be used to build a list and database. This script is not used to just build a data-
base (skipping the list of files step), as this can be simply done by just calling "cscope -b".
Normally, cscope will do its own indexing, but this script can be used to force indexing. This is useful if you need to recurse into sub-
directories, or have many files to index (you can run this script from a cron job, during the night). It is especially useful for large
projects, which can contstantly have source files added and deleted; by using this script, the changing sources files are automatically
handled.
Currently, any paths containing "/CVS/" or "/RCS/" are stripped out (ignored).
OPTIONS
-f database_file
Specifies the cscope database file (default: cscope.out).
-i list_file
Specifies the name of the file into which the list of files to index is placed (default: cscope.files).
-l Suppress the generation/updating of the cscope database file. Only a list of files is generated.
-r Recurse into subdirectories to locate files to index. Without this option, only the current directory is searched.
-v Be verbose. Output simple progress messages.
